Diffusion of binary and ternary gases through catalytic and non-catalytic membranes has been studied experimentally at atmospheric pressure. These experiments were conducted in a modified Wicke-Kallenbach diffusion cell consisting of two continuously stirred gas volumes separated by a membrane. The equipment was suitable to measure fluxes of components through the membrane in the absence of gas...

In this study the catalytic dehydrogenation of ethylbenzene to styrene was investigated in a simulated tubular sodalite membrane reactor. The high quality microporous sodalite membrane was synthesized by direct hydrothermal method and characterized by single gas permeation measurements. The performance of the prepared membrane showed high potential for application in a dehydrogenation membrane ...

Vapor transfer is an important phenomenon in various thermally driven membrane processes such as membrane distillation (MD), membrane evaporation and membrane condensation. In this study, we explore the mass transfer phenomena in sweeping gas membrane distillation (SGMD) by systematically investigating the effects of operational parameters on the process performance. It is found that mass trans...

Membrane technology is of significant importance in water treatment applications, and also gaining momentum other separations due to advantages such as environmentally friendly operation, less complex lower-cost operating conditions compared alternative options. To provide for sustainable efficient membrane-based the selection appropriate membranes crucial. Such a based on membrane characteriza...

This work deals with modeling and simulation of SO2 removal in a ceramic membrane by means of FEM. A mass transfer model was developed to predict the performance of SO2 absorption in a chemical solvent. The model was based on solving conservation equations for gas component in the membrane. Computational fluid dynamics (CFD) of mass and momentum were used to solve the model equations. The simul...

The objective of this study was to develop an innovative and advanced integrated “membrane oxidation” system for the treatment domestic wastewater by coupling membrane bioreactor (MBR), nanofiltration (NF) ozonation. Five contaminants were selected (acetaminophen, carbamazepin, sulfamethoxazole, tetracyclin terbutryn). MBR effluent samples have been fully characterized using conventional analys...
