A neuro‐based computing technique is used for simulation of olefin plants at industrial scale. Artificial neural networks are applied to estimate flow rate of the main products of olefin unit from some available information (flow rate of feed streams and operating condition of furnaces). Structure of the smart model is determined through trial‐and‐error procedure using the real plant information over

In this study, the influence of dissolution of hydrocarbons extracted by different solvents from oily sludge on petroleum products was studied by ASTM quality control tests. The results indicated that utilizing the shaker had a higher extraction percentage than the mixer. Besides, chloroform held the highest extraction of TPH (95.8%). The extracted TPH by solvents had almost an undesired effect on

A Pitot‐tube jet pump for separating and transporting liquids of different densities is in use for processing oil‐polluted water. The remaining oil‐in‐water (OiW) concentration is a main indicator for the process efficiency and requires a precise measuring method. Hence, a simple approach delivering reliable oil concentrations has been developed in this project. The measurement principle relies on

In this novel work, the utilization of iron (II) hydroxide (Fe(OH)2) slurry as the absorbent in wet flue gas desulfurization was investigated. The most important feature for selecting Fe(OH)2 is that iron sulfate, formed by captured sulfur dioxide, can be converted back into Fe(OH)2. At first in the experiments, bubble column was used with continuous gas and liquid flow. Secondly, perforated plates

In this work, experimental study of microfiltration membrane separation process in oil effluent treatment was investigated. The flux of Poly(styrene‐co‐acrylonitrile) with 25wt% (SAN25) and 30wt% (SAN30) of acrylonitrile fraction using different solvents in two different feed types (distilled water and 5000mg/lit stabilized oil‐in‐water emulsion) was studied. In the case of O/W emulsion, the performance

The bioliq®‐process, developed at the Karlsruhe Institute for Technology (KIT) aims at the production of synthetic fuels and chemicals from biomass. The bioliq®‐technology is based on a two‐step process with decentral pyrolysis for the production of a transportable slurry from residual biomass (e.g. straw) and the central entrained‐flow gasification of the slurry by using BtL technology. This study

The energy‐saving potential of the internal thermally couple air separation column is well‐established, but; there are distinct dynamic characteristics and control loop interaction that make it inflexible to control. To take care of high‐purity ITCASC control complications, we formulated a state‐space model predictive control (MPC). A direct finite‐horizon control approach is exploited to align the

This study aimed to synthesize chitosan/tripolyphosphate/mushroom green composite (C‐TPP‐PEE) and evaluate its adsorption performance of Reactive Orange 16 (RO16) dye by using the batch technique. Fourier‐transform infrared spectroscopy, thermogravimetric analysis and field emission scanning electron microscope were employed to characterize the C‐TPP‐PEE. The maximum adsorption capacity of the RO16

The trend of increasing product diversity and decreasing production amounts lead to the requirement of higher flexibility of production processes of specialty chemicals. Conventional distillation columns, mostly equipped with structured packings, lack the flexibility to handle product changeovers and throughput. Thus, a newly designed distillation column for specialty chemicals is presented in this

The synthesis of solketal is one of the innovative routes of glycerol valorization into added value products, and the simulation of the process requires the knowledge of thermodynamic properties that are not still available in the literature. In this work, the specific heat capacity as a function of temperature and the enthalpy and entropy of formation of all compounds involved in the reaction were

Forward osmosis (FO) has recently grown interest in wastewater treatment, seawater desalination and brackish groundwater. This study involves the use of response surface methodology (RSM) for prediction and optimization of FO process using low concentration Draw Solution (DS). The process variables were Feed Solution (FS) temperature, DS concentration & FS concentration. These variables were subjected

In this work, a study on the sensitivity of benchmark tubular reactors subject to temperature and concentration external perturbations is presented. Hurst exponent is used as a sensitivity indicator, which is calculated from temperature time‐series at each position of the reactor. Two case studies were evaluated, a pseudo‐homogeneous axial dispersion dimensionless tubular reactor and a heterogeneous

Microfluidic droplets have been widely used in various fields such as biomedicine, aerospace, energy utilization and chemical engineering due to their advantages of large specific surface area, uniform size, stability and easy control. The double T‐shaped microchannel has the characteristics of rapid preparation of microdroplets with controllable size and good uniformity. Through three‐dimensional

Design of industrial crystallization processes usually employs laboratory‐scale experimental data which must be correlated with the full‐scale process for effective technology transfer. In this context, the measured growth rates of single crystals of Ibuprofen in stagnant ethanolic solutions are compared with data recorded for a population of crystals crystallized in an agitated 7ml reactor. The single

Thin film composite (TFC) forward osmosis membranes developed on different woven and non‐woven backing fabrics as support. Embedding backing fabrics have a significant effect on membrane film sublayer by impressing porosity and membrane total mechanical strength and total thickness. Woven and nonwoven backing fabric support had been used for FO membrane cast in commercial scale. In the lab scale, also

Microparticles embedded with cellulose Nanofibers (CNF) is produced via spray drying. The micro‐droplets are created in the spray dryer via atomization. The solvent evaporates from the droplet, and the dried particles are formed. The drying kinetics on the scale of one droplet is not well understood. Drying of single droplet CNF suspension was investigated in an acoustic levitator. The drying kinetics

In this study, adsorption of methane and nitrogen, in pure and mixture state, on Faujasite (FAU) zeolite was investigated using molecular dynamics simulation. FAU zeolites with Si/Al ratios of 1, 2, and 3 were tested to evaluate the effect of changes in zeolite structure. Adsorption isotherms of CH4 and N2 were derived using molecular dynamic simulation with COMPASS force field at 293, 308, and 323

A mathematical model was developed based on Amon and Denson model for the supercritical foaming (SCF) with two‐step depressurization rate. The model was provided according to the law of conservation of momentum, the law of conservation of mass, and a reformulation of the shell size for the second step depressurization in comparison with the shell size for the first step depressurization. The model

Green Energy for Environmental Sustainability The pursuit for cleaner and more efficient sources of renewable energy has strengthened tremendously over the past few decades. Scientists and researchers across the globe have rounded up their resources and dedicated their efforts to developing renewable sources of green energy that can potentially solve the global energy crisis. The International Conference

Hydrogen production from food waste using biochemical and thermochemical methods was reviewed in this paper. Generally, fermentation, a bio‐chemical method is considered to be more suitable for hydrogen production from food waste and performance of any fermentation unit depends upon many factors such as substrate composition, type of pretreatment, reactor configuration, and operating parameters such
