A short-cut design method based on Residue Curve Maps (RCMs) is applied to the conceptual design of Distillation-Pervaporation in a Single Unit (DPSU) columns. Unlike to a conventional hybrid distillation-pervaporation column, in a DPSU system the pervaporation module is located inside the column. The distillation and pervaporation mechanisms are fully coupled, allowing overcoming azeotropic conditions

Coalescence deoiling is a rapid and effective removal method of dispersed oil in wastewater. However, the coalescence process can not be used to treat the emulsion containing surfactants. In this paper, a Zeolite/Mg2+/cyclodextrin/Fe3O4 composite material is designed for simultaneous demulsification and coalescence deoiling of the emulsion containing surfactants. The zeolite can provide a considerable

In this paper, the conventional reactive distillation (CRD) of toluene diisocyanate (TDI) production process is designed and optimized by minimizing the total annual cost (TAC). In order to make the HCl content in the side stream of the reactive distillation correspond with the specifications of the CRD process, a lot of energy needs to be consumed. Therefore, a reactive distillation dividing-wall
