Separation with Polymeric Membranes.

Polymeric Gas Separation Membranes: What Makes them Industrially more Attractive?

Practical Techniques for Improving the Performance of Polymeric Membranes and Processes for Protein Separation and Purification

Protein separation and purification technologies play an essential role in various industries including but not limited to pharmaceuticals, dairy as well as the food sector. Accordingly, a wide variety of techniques such as chromatography and electrophoresis has been developed and utilized extensively over the years for this purpose. Despite their widespread acceptance, conventiona...

Correlation of separation factor versus permeability for polymeric membranes

The separation of gases utlhzmg polymenc membranes has emerged mto a commercially utlhzed unit operation It has been recogmzed m the past decade that the separation factor for gas pairs vanes inversely with the permeablhty of the more permeable gas of the speclflc pair An analysis of the literature data for bmary gas mixtures from the hst of He, Hz, 02, Nz, CH4, and COz reveals an upper bound r...

Mechanistic Modeling of Organic Compounds Separation from Water via Polymeric Membranes

A mathematical model considering mass and momentum transfer was developed for simulation of ethanol dewatering via pervaporation process. The process involves removal of water from a water/ethanol liquid mixture using a dense polymeric membrane. The model domain was divided into two compartments including feed and membrane. For a description of water transport in ...

Functionalized Polymeric Membranes for CO2 Capture

Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...
