    A continuous HPPO lab-scale pilot plant was designed and tested for the production of propene oxide via HPPO (Hydrogen Peroxide Propene Oxide) process. The plant was equipped with a continuous stirred tank reactor, able to work under nitrogen pressure with liquid propene. Attention was paid on the feed system and the plant control, being the lab-scale pilot plant completely automated. Hydraulic tests were performed to check the performance of the plant; a fluid-dynamic characterization was conducted to evaluate the residence time distribution. Propene oxide synthesis experiments were carried out to evaluate both hydrogen peroxide conversion and propene oxide selectivity. The collected data were interpreted with a recently published kinetics, validating the developed model, obtaining satisfactory results, also in simulating the start-up transient state of the reactor. The model can be considered of high utility in designing and optimizing HPPO process, to achieve high reactants conversion and propene oxide yields.

  • Data-driven optimization of processes with degrading equipment
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16

    In chemical and manufacturing processes, unit failures due to equipment degradation can lead to process downtime and significant costs. In this context, finding an optimal maintenance strategy to ensure good unit health while avoiding excessive expensive maintenance activities is highly relevant. We propose a practical approach for the integrated optimization of production and maintenance capable of incorporating uncertain sensor data regarding equipment degradation. To this end, we integrate data-driven stochastic degradation models from Condition-based Maintenance into a process level mixed-integer optimization problem using Robust Optimization. We reduce computational expense by utilizing both analytical and data-based approximations and optimize the Robust Optimization parameters using Bayesian Optimization. We apply our framework to five instances of the State-Task-Network and demonstrate that it can efficiently compromise between equipment availability and cost of maintenance.

  • Heat capacity prediction of ionic liquids based on quantum chemistry descriptors
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16
    Xuejing Kang, Xinyan Liu, Jianqing Li, Yongsheng Zhao, Hong-Zhong Zhang

    Heat capacity is an important and fundamental physicochemical property of ionic liquids (ILs). Here, a new class of quantum chemical descriptor, namely electrostatic potential surface area (SEP) descriptor, is employed to predict the heat capacity of ILs. In this study, 2416 experimental data points (254.0-1805.7 J mol-1 K-1) covering a wide temperature range (223.1-663 K) were employed. Multiple linear regression (MLR) and extreme learning machine (ELM) are applied to establish the linear and nonlinear models based on the SEP descriptors, respectively. The obtained six-parameter models show good predictive performance. The R2 of the linear MLR model is 0.988 for the entire set, while the ELM model has a higher value of R2=0.999, indicating the robustness of the nonlinear model. The results suggest that the SEP descriptors are closely related to the heat capacity of ILs and can be potentially used to predict the properties of ILs.

    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16

    Self-optimizing control technologies are a well-known study field of control structure design, having a robust mathematical background. With the aid of commercial process simulators and numerical packages, process modelling became an easier task. However, dealing with extremely large and complex systems still is a tedious task, and sometimes not feasible, even with these innovative tools. Surrogate models, also called metamodels, can be used to substitute partially or totally the original mathematical models for prediction and optimization purposes, reducing the complexity of evaluating large-scale and highly non-linear processes. This work aims at applying recent self-optimizing control techniques to surface responses of processes using kriging method as reduced model builder. A procedure to apply Self-Optimizing control to surrogate responses was described in detail, together with how the optimization can be done. Well-known case studies had their surface responses successfully built and analyzed to generate using the techniques cited, the optimal selection of controlled variables that minimizes the worst-case loss, and the same results were found when compared with the implementation in the original models from previous authors. The results indicate the effectiveness of the reduced models when applied to design self-optimizing control structures, simplifying the task.

  • The Role of Solvent Composition and Polymorph Surface Chemistry in the Solution-Mediated Phase Transformation Process of Cefaclor
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16
    Chang Wang, Ling Zhou, Xia Zhang, Yongfan Yang, Qiuxiang Yin, Kevin J. Roberts

    The solution-mediated phase transformation process from cefaclor dihydrate to an ethanol-water solvate is analyzed by optical microscopy, powder X-ray diffraction, scanning electron microscopy and molecular modelling. The solution concentration and polymorphic composition during slurry transformation, as monitored using UV and Raman spectroscopy, respectively, reveal that the dihydrate transforms to the ethanol-water solvate at a low ethanol concentration in the mixture solvent. The transformation process is controlled by the growth of ethanol-water solvate, which nucleates on the surfaces of the dihydrate crystals. Molecular simulation confirms the critical point of transformation between the dihydrate and the ethanol-water solvate, consistent with the experimental results. The results demonstrate the importance of the solvent composition and surface chemistry of dihydrate in promoting the heterogeneous nucleation of ethanol-water solvate and provides guidance for the process control for the target form of cefaclor required.

    New experimental densities for diethylamine (DEA), dibutylamine (DBA), and tributylamine (TBA) at 11 isotherms in the range of 293.15–473.15 K and 18 isobars up to 37.5 MPa are reported. PT measurements (176 experimental data points) have been performed using a high-pressure vibrating-tube densimeter. These data were correlated with a new modified Tait-like equation considering standard deviations of less than , then isothermal compressibility and thermal expansion coefficient were calculated. This study is supported by the results of modeling using the perturbed-chain statistical associating fluid theory (PC-SAFT). The parameters of PC-SAFT equation of state (EoS), for pure solvents, were rigorously determined by fitting the equation to the liquid PT experimental data. In this study, the correlations, which are based on minimizing the total objective functions—density, pressure, and temperature—simultaneously, were developed to estimate the PC-SAFT parameters. The model reasonably predicted the behaviour of PT and the first- and second-derivatives properties such as isothermal compressibility , thermal expansion coefficient , isobaric heat capacities , and speed of sound (u). The results undoubtedly suggest that the model performance is enhanced for either cases of the new modified Tamman–Tait equation and the PC-SAFT EoS, based on employing the proposed parameters.

  • Highly sensitive luminescent probe of aniline and trace water in organic solvents based on covalently modified lanthanide metal-organic frameworks
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16

    A novel europium functionalized MOF named Eu3+@UiO-66-NH2-IM is robustly synthesized via covalent PSM (post-synthetic modification). The ligand of matrix MOF is covalent modified via imidazole-2-carboxaldehyde after the UiO-66-NH2 is synthesized. The successful transformation of amino groups to imine groups is confirmed by FTIR analysis. The modified MOF named UiO-66-NH2-IM shows outstanding crystalline stability. After Eu3+ doped into UiO-66-NH2-IM, the as-prepared fluorescent MOF displays characteristic emission line of Eu3+. Discussion of the tunable emission color of the modified MOF is included and white light integration could be achieved through altering the ratio of Eu3+ doped into the MOF. What’s more, the luminescent transparent film based on Eu3+@UiO-66-NH2-IM can emit white light under proper excitation wavelength, which may be helpful to some potential applications in lighting. In addition, Eu3+@UiO-66-NH2-IM shows different emission response in water and organic solvents, and it is further developed into sensitive probe for the detection of water content in organic solvents (ethanol, DMF) with low detection limits ( 0.088%, and 0.054%, respectively) by utilizing its quenching behavior in water. Meanwhile, Eu3+@UiO-66-NH2-IM displays greatly selective and sensitive response for detecting aniline with a low detection limit (0.072%), a broad linear range (0-3.75%), and the signal of the detection is obvious which can be seen clearly under the irradiation of UV light.

  • Physico-chemical modeling for pressurized hot water extraction of spruce wood
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16
    Waqar Ahmad, Susanna Kuitunen, Andrey Pranovich, Ville Alopaeus

    The study of reaction kinetics and process modeling plays a vital role in the development and optimization of industrial processes. In this study, a physico-chemical model is presented for pressurized hot water extraction of spruce wood meal to facilitate process development and optimization. Model takes into account several relevant phenomena during the extraction process, including acid-base reaction equilibrium, irreversible reaction kinetics, ion exchange, and mass transfer. The system is modeled by assuming two liquid phases i.e. liquid external to wood fibers and fiber bound liquid to enable inclusion of ion exchange. The non-ideal behavior of system (due to presence of ions) is considered by utilizing activities instead of concentrations. The scission of hemicellulose polymers into oligomers and monomers is modeled by population balance approach of discretized categories. Model parameters are optimized by fitting the model output to experimental data reported in the literature. The presented model aims to be the most comprehensive description of the phenomena taking place during the hot water extraction of softwood to date. Such physico-chemical models are able to provide better understanding for parts of process, which cannot be followed directly due to tediousness of analytical methods. It also reveals gaps in the present knowledge and provides one-step towards further development.

    Carboxymethyl β-cyclodextrin (CM-β-CD) was introduced to obtain surface-modified nano-hydroxyapatite (CM-β-CD-HA). The results of Fourier transformation infrared (FTIR), X-ray diffraction pattern (XRD), dispersion test, X-ray photoelectron spectra (XPS), thermal gravimetric analysis (TGA) showed that CM-β-CD was surface-grafted on the n-HA by the reaction of carboxyl group of CM-β-CD with Ca2+ ions during the formation of n-HA. The best appropriate reaction condition was obtained, which accomplished CM-β-CD-HA with the greatest grafting amount and the best dispersion. Then, CM-β-CD-HA was introduced into poly(lactide-co-glycolide) (PLGA) with different amounts of 5 wt%, 10 wt% and 15 wt% in weight by solution mixing method, and the properties of CM-β-CD-HA/PLGA composites were also investigated by electromechanical universal tester, XRD, scanning electron microscope (SEM), differential scanning calorimeter (DSC) and polarized optical microscopy (POM). The results indicated that the CM-β-CD-HA with 10 wt% had the best mechanical reinforce effectiveness for PLGA, whose tensile strength of the CM-β-CD-HA/PLGA composite was 14.84% higher than that of pure PLGA due to the best dispersion and promotion crystallization, suggesting the CM-β-CD-HA obtained by the new surface-modification strategy had a great potentiality to be used for a reinforce filler for PLGA as bone material in the future.

  • Accelerated Construction of High-Silica RHO and CHA Zeolites via Interzeolite Transformation and their NH3-SCR Performances after Copper Exchange
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16

    Rapid and selective synthesis of high-silica zeolites, including topologies of RHO and CHA, has been realized by interzeolite transformation process. The XRD patterns and morphology images collected within the whole procedure of aging and reaction suggest that the interzeolite transformation from FAU to RHO zeolite proceeds in a way of directly reassembling the locally ordered FAU-derived species, but as quasi-amorphous domains, on the surface of the RHO moieties. Therefore, the crystallization process could be remarkably accelerated by circumventing the incipient nucleation from the fundamental Si/Al species. Thenceforth, the high-silica descendant zeolites obtained by interzeolite transformation were all employed in the NH3-SCR process after copper ion exchange to a similar level. Therein, the RHO zeolite achieves fine trade-off between the activity and durability even after hydrothermal treatment at 800℃, which indicates that the durability issue involved could be validly fixed by this zeolite and once again highlights the advantages of the interzeolite conversion process.

  • Robust and flexible cellulose nanofiber/multi-walled carbon nanotube film for high-performance electromagnetic interference shielding
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-16
    Haoruo Zhang, Xunwen Sun, Zhengguang Heng, Yang Chen, Huawei Zou, Mei Liang

    For the preparation of lightweight and high performance electromagnetic interference shielding material, the poor dispersion of carbon nanotube (CNT) and the weak interfacial strength degrade the mechanical properties of the polymer based composite with extremely high filler contents. Herein cellulose nanofibers (CNF) prepared by TEMPO-oxidized exhibits a dispersive action for multi-walled carbon nanotube (MWCNT) without chemical functionalization of the MWCNT or the use of surfactant. Thus, the robust and flexible CNF/MWCNT composite film can be fabricated by simple vacuum filtration and hot-pressing method. This composite film (thickness 0.15 mm) shows an EMI SE of 45.8 dB in the X-band. Thanks to the all-fiber structure and the association between CNF and MWCNT, it exhibits good flexibility and tensile strength up to 48 MPa, which is superior to other reported MWCNT-based films for electromagnetic shielding, giving it the potential to be used in flexible electronics and wearable devices.

  • NiO-modified Coconut Shell based Activated Carbon Pretreated with KOH for the High-efficiency Adsorption of NO at Ambient Temperature
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-15
    Fengyu Gao, Xiaolong Tang, Hong hong Yi, Bowen Zhang, Shunzheng Zhao, Jiangen Wang, Tian Gu, Yuhe Wang

    In this study, coconutshell-, coal- and wood-based activated carbon were selected as the adsorbents for NO adsorption. KOH and transition metal oxides (CuO, FeOx and NiO) were further adopted to improve the NO removal efficiency and adsorption capacity at ambient temperature. The results showed that CSAC- KOH(3)-NiO(10) adsorbents (Coconut Shell based Activated Carbon modified by 3% KOH and then 10% NiO) achieved the highest removal efficiency of NO (above 95.6%) and adsorption capacity (5.26 mg/g) within 60 min. XPS and NO-TPD results indicated that the increase of –C–O and OH-/Ox- species might be the reasons for good removal efficiency of NO over CSAC-KOH, while the increase of OH-/Ox- and lattice oxygen (O2- in Ni-O) species for CSAC-KOH-NiO sample. The medium sites of the active adsorbed oxygen (Ox-) species and strong sites of lattice oxygen are the major adsorption sites on the surface of CSAC-KOH-NiO. The possible NO adsorption process were proposed that the main nitrite species (-NO2) might be generated by lattice oxygen (O2-) in Ni-O sites with the stimulation effects of active oxygen (Ox- or/and [O]), while NO- and –NO3 species were generated from -C-C, -C=C and -C=O sites.

  • Rapid CO2 adsorption over hierarchical ZSM-5 with controlled mesoporosity

    Abstract: Alkyltrimethoxysilanes with different chain length (trimethoxypropylsilane, trimethoxyoctylsilane and dodecyltrimethoxysilane) were utilized as mesopore-generating agent to synthesize hierarchical ZSM-5 samples with different amount of mesoporous volume. The samples were characterized by X-ray powder diffraction (XRD), nitrogen adsorption-desorption, scanning electron microscope (SEM), transmission electron microscopy (TEM) and CO2-temperature-programmed desorption (CO2-TPD). With the growth of chain length, the alkyltrimethoxysilanes showed low reactivity and affinity for the surfaces of zeolite precursors due to the increase of hydrophobic character of the alkyl moiety, which resulted in the decrease of mesoporous volume. CO2 adsorption behaviours of the samples including adsorption capacity, adsorption kinetics, adsorption selectivity, adsorption thermodynamics and adsorbent stability were studied. The experimental results indicated that hierarchical ZSM-5 modified by trimethoxypropylsilane exhibited the highest mesopores volume (0.12 cm3·g-1), corresponding to the fastest capture rate (about 2.5 times of conventional ZSM-5) and the highest capture capacity (2.15 mmol·g-1 at 25 °C and 100 kPa). Therefore, hierarchical ZSM-5 synthesized by the alkyltrimethoxysilanes with short chain length can generate the more extra mesopores and active adsorption sites, which provided a new strategy to regulate the structure of ZSM-5 for rapid CO2 adsorption.

  • Investigating adsorptive deep desulfurization of fuels using metal modified adsorbents and process intensification by acoustic cavitation

    The harmful impact on environment due to SOx emissions from fuels and increasingly stricter norms over the years, have amplified deep desulfurization challenges, consequently enhancing attractiveness of adsorptive separations. The present work focusses on investigating metal modifications and process intensification using acoustic cavitation for improving S removal behaviour and selectivity. The proof of concept was elucidated using two model adsorbents, one- commercial Shirasagi TAC adsorbent and other- newer adsorbent derived from Cassia fistula biomass. Single and double metal modifications were studied using zinc, cobalt, nickel and copper. An attempt was made to further improve the sulfur removal using process intensification - acoustic cavitation coupled with adsorption. The removal of three refractory sulfur compounds viz. thiophene, benzothiophene, dibenzothiophene was studied and the performance was compared for both single and double metal modifications apart from process intensification. In the case of TAC, a high capacity for sulfur removal, up to 23 mgS/g was obtained, especially for dibenzothiophene. Process intensification using cavitation coupled with adsorption further improved sulfur removal to the extent of 100 % and for metal modified TAC, capacity increase up to 38mgS/g for dibenzothiophene was obtained. The results indicate that combined effect of metal modification and process intensification can substantially improve the sulfur removal efficiency of carbon adsorbents.

  • Functionalized Aramid Fibers & Composites for Protective Applications: A Review
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-15
    Prakash Gore, Balasubramanian Kandasubramanian

    Technological growth in advanced ammunition, and weapons has led to development of protective anti-ballistic composites, which are mostly based on Aramid fibers, as they absorb high impact energy, arising from penetrators. Enhanced performance of Aramid fibers (modulus~112,400MPa), is attributed to their compact molecular-structure, hydrogen-bonding, high-crystallinity, and high density (~1.44g/cm3). Methodologies like Layer-by-Layer, shear-thickening, yarn-pullout, surface-functionalization via nanomaterials, etc. have been reported for modification of Aramid fibers, which are widely used with thermosets like Epoxy (due to process-friendliness). Recently, researchers are exploring thermoplastics with Aramids, due to their higher toughness, chemical-resistance, and thermal stability. Modification of Aramid fibers is mostly performed using nanomaterials e.g. carbon-nanotubes, graphene, silk fibroins, SiO2, ZnO, for enhancing their performance, and minimizing fiber-buckling under load. Following review presents advances in modification of Aramid fibers using nanomaterials with emphasis on thermoplastics for protective applications, their stress transfer mechanisms, Life Cycle Analysis, and concludes with their recycling/recovery methods.

    The work was focused on investigating how Fe-doped CeO2 composites affect physicochemical properties in relation to NO + CO reaction. Coprecipitation method was adopted to prepare CeO2-FeOx mixed oxides. NO + CO reaction as well as Temperature Programmed Reduction (H2-TPR), N2-physisorption (BET), Oxygen Storage Capacity (OSC), X-ray Photoelectron Spectroscopy (XPS), X-Ray Diffraction (XRD), and in situ Fourier Transform infrared spectroscopy (in situ FT-IR) were used to characterize resulting samples. These results implied that appropriate doping amount of FeOx would cause an obvious change on CeO2 structure and properties. And the catalyst with the ratio of (Ce: Fe = 1 : 0.35) showed the best catalytic properties. In addition, during calcination, adding a few FeOx could benefit the formation of low valence iron to larger extent. This synergetic effect contributed to the formation of a larger number of Fe2+ and oxygen vacancies.

    Nickel/cerium-zirconium oxide (Ni/Ce50-Zr50) and manganese promoted Ni/Ce50-Zr50 (Ni-Mn/Ce50-Zr50) catalysts were prepared using impregnation method and used in dry reforming of methane. The catalysts were characterized by H2 temperature programmed reduction, transmission electron microscopy, X-ray photoelectron spectroscopy, CO2 temperature programmed desorption, X-Ray diffraction, in-situ diffuse reflectance infrared Fourier transform spectra, and thermo-gravimetric analysis. Manganese promoter facilitated the formation of the reaction intermediate –CH2OH species at low temperature. A synergistic effect between Ni and Mn species enhanced the adsorption of CO2 on Ni-Mn/Ce50-Zr50. Manganese promoter not only enhanced the catalytic activity but also led to high H2/CO ratio product. At 600 °C, under atmospheric pressure, with 20,000 h-1 gas hourly space velocity and CH4/CO2/Ar = 1/1/8, on Ni-Mn/Ce50-Zr50 catalyst, the CH4 conversion (38.7%), CO2 conversion (40.4%), and the H2/CO ratio (0.83) were all much higher than those on both non-promoted Ni/Ce50-Zr50 and SiO2 supported Ni-Mn catalysts.

  • Green synthesis of thiuram disulfides with CO2 as an acid agent for sustainable development
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-15
    JiaYu Hu, Kai Wang, Jian Deng, Guangsheng Luo

    A green synthesis method for the oxidation of sodium dialkyl dithiocarbamate to the corresponding thiuram disulfides was developed in the presence of CO2 as the neutralizing agent, H2O2 as the oxidant and water as the solvent. The method could provide much greener reaction conditions, convert CO2 to a relatively high-quality product without H2SO4 consumption, and reach the high yields and purity of products. The effects of CO2 flow rate, reaction temperature, concentration, dropping speed and excess degree of hydrogen peroxide, as well as the concentration of sodium dimethyldithiocarbamate, were investigated. By HPLC-MS detection of the mother liquor, it was found that the organic byproducts of this oxidation process were the hydrolysis product of TMTD (tetramethyl thiuram disulfide), sodium dimethylcarbamothioate, and the peroxidation product of sodium dimethyldithiocarbamate, sodium (dimethylamino)(thioxo)methanesulfonate, which have been rarely proven experimentally by previous work. These byproducts generated in the latter stage of the oxidation process. Therefore, the possible chemical reactions of this synthesis process were proposed. On the basis of these reactions, a 0.6 stoichiometric hydrogen peroxide dosage was added, the mother liquor was recycled, and no organic byproduct was found after five stages of recycling. As a result, the discharge of wastewater was greatly reduced. Tetraethyl thiuram disulfide was also synthesized by this method to demonstrate its universality.

    TiO2 supported transition metal oxides were investigated for the direct decomposition of nitrogen oxides (NOx) at lower temperatures. The results showed that the catalytic performance strongly depends on the kind of transition metal oxide deposited on the TiO2. Among the various catalysts examined, Mn/TiO2 and Co/TiO2 exhibited relatively high NOx conversion at lower temperatures in the presence of 3 vol.% O2. The oxygen in the reaction stream had a positive impact on the NOx decomposition over the Mn/TiO2 catalyst. We have not observed any TiO2 phase conversion from anatase to rutile in the Mn/TiO2 during the NOx decomposition reaction at different temperatures (100‒350 oC). NOx decomposition activity was shown to be governed by the surface labile oxygen rather than the gas phase oxygen. The Mn/TiO2 catalyst exhibited a good resistance to 10 vol.% H2O and 100 ppm SO2.

    This study focused on the investigation of emulsion stability, membrane breakage and emulsion swelling of emulsion liquid membrane for acetaminophen (ACTP) removal. Stability of the emulsion as well as its effectiveness in removing ACTP from aqueous solution were considered for the optimization of parameters. Parameters involved are carrier and surfactant concentration, emulsification time as well as volume ratio of membrane to internal phase. The effects of membrane breakage and emulsion diameter on the removal capacity of ACTP were also studied. Results showed that the optimal condition to produce a very stable emulsion and to achieve maximum ACTP removal efficiency were found to be 4wt.% of trioctylamine (TOA) and Span 80, W/O volume ratio of 3 and 10 minutes of emulsification time. The prepared emulsion was found to effectively remove 85% of ACTP at minimal membrane breakage of 0.19%.

  • Ultimate Reaction Selectivity Limits for Intensified Reactor-Separators
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-14

    The Continuous Flow Stirred Tank Reactor (CFSTR) Equivalence Principle, developed by Feinberg and Ellison, proves that any and every reaction/mixing/separation process is equivalent to a process comprising at most R+1 CFSTRs and a perfect mixer-separator, where R is the number of linearly independent chemical reactions. Frumkin and Doherty showed the CFSTR Equivalence Principle can be used together with global optimization to find the maximum selectivity of a chemistry independent of process design. These selectivity targets are useful in the context of process intensification as they represent ultimate selectivity improvements that can be achieved by combining multiple unit operations into a single device. In this work, the model is reformulated as a mixed-integer nonlinear program to solve this nonlinear and non-convex optimization problem. We implement a more robust, deterministic global optimization using a spatial branch-and-bound algorithm (BARON) to investigate the selectivity limits for the production on acrolein, a chemistry which has thirteen components and seventeen reactions. We find maximum selectivities that are lower than the stoichiometric selectivity limit and can be used as a target for process intensification.

    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-14

    A kinetic model for hydrocracking of a real Vacuum Gas Oil feedstock (VGO) with 217 discrete lumps defined by carbon number and structure was extended from the model published by our group. A model with two additional parameters taking into account catalyst composition and geometrical properties was developed. The 17-parameter estimation was performed from 1332 experiment data points obtained in a semi-batch reactor at 120 bar and 400°C at various reaction times [0-338min] for 3 bifunctional catalysts and is validated against 8 catalysts with different zeolite and metal loadings (resp. [0.5-1.5] and [0.6-0.7]) based on a statistical analysis. A macroscale relation for cracking rates, dependent on zeolite loading and catalyst internal geometry, was proposed. This interpretation gives good agreement between calculated and measured mass fractions, VGO conversion and Middle Distillate, Naphta and LPG selectivities. Critical analysis of the estimated kinetic constants confirms the well-known bifunctional mechanism derived from model molecules.

  • The Insight in Copolymerization of Methyl (Meth)acrylate and 1-Octene with Aluminum Trichloride
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-14

    Aluminum trichloride (AlCl3)-catalyzed copolymerization of polar monomers, including both methyl methacrylate (MMA) and methyl arcylate (MA), with non-polar 1-octene is investigated. The copolymerization of MMA and 1-octene produce copolymers with acceptable productivity in the present of AlCl3, but no alternating copolymer can be obtained even in a 1-octene rich condition (n(1-octene)/n(MMA)=6.14/1). However, AlCl3-catalyzed copolymerization of MA and 1-octene unveils that MA is more feasible than MMA to copolymerize with 1-octene for the formation of alternating copolymer. Alternating copolymer of MA and 1-octene can be obtained even at a MA-rich condition (n(1-octene)/n(MA)=0.58/1). Meanwhile, temperature shows significant impact on the copolymerization behaviors. Performing AlCl3-catalyzed copolymerization of MA and 1-octene at lower temperature leads to an increase in the molecular weight and the incorporation of MA into the backbone of the copolymer, probably due to low temperature-enhanced complexation between AlCl3 and the ester functionality.

  • Anionic polyelectrolytes synthesized in aromatic free oils process for application as flocculants in dairy industry effluent treatment

    The wastewater generated from many industries contains suspended and dissolved solids, including organic and inorganic particles, metals and other impurities. Direct flocculation is regularly used to neutralize the charge of the colloidal particles and bridge the destabilized particles together to form flocs, in a cost and time-effective way. This work refers to the development of new anionic flocculants (co and ter-polymers) tailored to be used in dairy effluents treatment, using a synthesis process in which new oil phases free of aromatics are applied. Regarding the ter-polymers, anionic polyacrylamides were synthesized in the presence of three different hydrophobic monomers, at different concentrations. Flocculation performance was evaluated using an effluent from dairy industry. Results show that the developed polyelectrolytes are very promising additives for the treatment of the mentioned effluent. For optimized conditions, 95% turbidity reduction, 44% COD removal and 57% total solids removal were achieved, with only 53 mg/L of flocculant.

  • Significantly Improving Strength and Damping Performance of Nitrile Rubber via Incorporating Sliding Graft Copolymer
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-14

    Aiming at high strength damping elastomers, the pre-crosslinked sliding graft copolymer (SGC) is incorporated into a nitrile rubber (NBR). The micro-structure characterizations reveal that SGC phase is dispersed in NBR matrix fairly uniformly with a distinct interphase. As SGC content increases, the loss factor of SGC/NBR blends gradually increases. The improved damping properties of SGC/NBR blends are attributed to the intrinsic high damping characteristics of SGC and the formed interfacial hydrogen bonds. In addition, the mechanical properties of SGC/NBR blends are unexpectedly improved. The tensile strength of SGC/NBR (20/100) is increased by 170%, comparing to that of neat NBR. The significantly increased tensile strength is ascribed to the increased orientation of NBR chains, due to the "pulley effect" of SGC and the successive rupture/re-association of interfacial hydrogen bonds. The high damping and mechanical properties of SGC/NBR blends render them potential in isolation rubber bearings application.

  • Computational Fluid Dynamics-Based Study of a High Emissivity Coil Coating in an Industrial Steam Cracker

    To assess the effect of applying a high emissivity coating to the reactor coils in a steam cracking furnace, a complete energy balance was made for two cases based on simulations of the radiant section, reactors, convection section and transfer line exchanger. A base case with a typical emissivity spectrum for a generic high-alloy steel was compared to a case with an artificially increased emissivity corresponding to a high emissivity coating. At the same cracking severity, coating the radiant coils increases the radiant section efficiency by 0.70 % absolute, reduces the required furnace firing rate by 1.73 % and reduces the flue gas bridge wall temperature by 14 K. Minor changes to the convection section lay-out are required to compensate for the shift in duty to the radiant section: the reactor feed is still fully preheated to the targeted crossover temperature but the production of high pressure steam is reduced.

  • Combined Natural Gas Separation and Storage based on in silico Material Screening and Process Optimization

    We propose an intensified process for combined separation and storage (CSS) of natural gas from various unconventional sources using a single multifunctional unit. The CSS process involves selectively storing methane in a column filled with an existing nanoporous zeolite material, while venting out the impurities. A multiscale model is used to optimize the methane storage and screen for the top zeolites under minimum purity requirements and loss constraints. Adsorption properties for different zeolites are obtained via Monte Carlo simulations. Zeolite SBN with a high storage capacity for pure methane is found to be most suitable for combined separation and storage over a range of feed compositions. A rank ordered list of top zeolites is also obtained along with the optimal process conditions. It is, however, observed that the effectiveness of the intensification of natural gas separation and storage is limited by the constraint on the loss of methane exiting the column.

    Composites materials are aimed to combine properties of their components to achieve a desired device functionality; however, synthesizing them in morphologies such as one-dimensional nanofibers is challenging. This article compares optical and electrical properties of ZnO-SnO2 composite nanofibers (CNFs) synthesized by electrospinning technique for energy harvesting applications with a similar CNFs (TiO2-SnO2) and their single component nanofibers (NFs). The composites formation is confirmed by X-ray and electron diffraction, energy dispersive X-ray, high-resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy analyses; the morphology is examined by HRTEM and field emission scanning electron microscopy. The electrochemical properties of the CNFs are studied by cyclic voltammetry, absorption spectroscopy, and electrochemical impedance spectroscopy. The CNFs behaved as a single semiconducting material of band gap ~3.32 (ZnO-SnO2) and ~3.15 (TiO2-SnO2) eV. The CNFs showed superior photoconversion efficiency (PCE ~5.60% for ZnO-SnO2 and ~8.0% for TiO2-SnO2 CNFs) compared to its binary counterparts SnO2 (~3.90%), ZnO (~1.38%) and TiO2 (~5.1%) when utilized as photoanodes in dye-sensitized solar cells.

  • Optimization of Cooler Networks with Different Cooling Types in Series and Parallel Configuration

    A cooler network is a significant part in a heat exchanger network, which is also vital to energy consumption and economic performance of the entire chemical manufacturing process. Currently, the work on the optimization of cooler networks chiefly has attached to optimization of circulating cooling water systems. However, few researchers have taken different cooling types with series and parallel configuration into consideration in the process of optimization on cooler networks. On the basis of lectotype among the dry type air cooler, spray type air cooler on behalf of wet type air coolers, and circulating cooling water system, a superstructure based optimization model with minimizing total annual cost as the objective function is established in this paper, formulated through mixed-integer nonlinear programming. Coolers with series and parallel configuration are allowed to reduce energy and water consumption and improve economic performance. Corresponding case studies show that the model can give a more economic efficient solution of the cooler network.

  • A process intensification methodology including economic, sustainability and safety considerations
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-13

    A methodology for the design of intensified processes that includes economic, sustainability and inherent safety factors is presented. Given an original synthesis problem to produce a desired chemical from a set of feedstocks, a base design is first generated, from which a gradual intensification procedure is carried out until a fully-intensified design with a minimum number of pieces of equipment is achieved. A novel approach in this work is that in addition to economic and sustainability factors, inherent safety metrics are evaluated at each step of the intensification methodology. In particular, the evaluation of inherent safety poses an important challenge because of the hybrid types of equipment units that inevitably appear as part of the intensification task. An adjusted FEDI index is included for such an evaluation as part of the methodology. Two case studies, one dealing with the production of isoamyl acetate and another one with the production of dioxolane products are taken to show the applicability of the intensification methodology. It is shown that a fully-intensified structure does not necessarily represent the best option when the three metrics are taken into account.

A new point of view to assess the controllability using the information from the singular value decomposition (SVD) technique is proposed. In the research, the techniques for comparing the open-loop and closed-loop analysis were standardized. The open-loop controllability index was calculated from the minimum singular value and the condition number of the certain areas in the frequency domain and a simplified index for measuring the singularity in SVD results. Then, the derived controllability index was compared with the normalized value of the Integral Absolute Error (IAE) of a proportional-integral (PI) controller obtained under closed-loop operation. Several different frequency areas were investigated to calculate the SVD and were used to compare the open-loop and closed-loop behaviors. The selected best distillation scheme was the same despite the chosen approach. Through the simulation study, it is verified that the newly proposed controllability index based on the condition number derived from open-loop responses can be useful to predict the best performance under closed-loop operation. This prediction is suitable to use into an optimization algorithm due to the structure of the proposed controllability index.

  • A Novel Design for Simultaneous Production of Biodiesel and Glycerol Carbonate from Soybean Oil
    Ind. Eng. Chem. Res. (IF 3.141) Pub Date : 2018-11-13
    Cuixia Xu, Qiang Xu

    Glycerol is the by-product of biodiesel production plants. The rapid increase of biodiesel production and demand has resulted in excessive glycerol supply in the market. Converting the cheap glycerol into high-value glycerol carbonate (GC) is a potentially valuable solution to the current worldwide excessive glycerol supply. In this paper, a novel optimal process for simultaneous production of biodiesel and GC (SBD&GC) from soybean oil has been developed and demonstrated, where annual productivities of biodiesel and GC are 35.4 and 4.4 kilotonnes, respectively. First, the proposed SBD&GC process has been investigated, modeled, and simulated. The glycerol is used as the feedstock for the GC production; meanwhile, the by-product of GC production, methanol, is recycled as the feedstock of the biodiesel production. Second, the optimization of the column duties has been performed by via thermal analysis analyzing the Column Grand Composite Curves (CGCC). In addition, a mathematic model for the heat integration of the SBD&GC process has been built to minimize the total utility cost. Based on the optimal solution, the detailed heat exchange network (HEN) design has been accomplished and demonstrated. Finally, economic evaluations for the newly designed SBD&GC process have also been performed. The results show that the developed SBD&GC process is very profitable, with a net present value (NPV) of $28,720,000 and a discounted cash flow return rate (DCFRR) of 60%.

    Biodiesel is fatty acid methyl ester derived from vegetable oils and/or animal fats that react with acyl acceptor. Biodiesel has beneficial in sustaining the healthy environment because of its biodegradable properties, renewable and non-toxic. Biodiesel is produced by transesterification process either with or without the catalyst. Transesterification through enzymatic routes gives advantage on high product purity, easy recovery and, green technology process. However, enzymatic catalyst is a time-consuming process, where it is the slowest pathway in biodiesel production. Thus, the application of ultrasonic in enzymatic transesterification is helping in reducing the reaction time. This review presents the advantage of ultrasonic assisted enzymatic transesterification over conventional enzymatic transesterification by considering the ultrasonic mechanism in accelerating the transesterification process.
