Thermodynamic efficiency, process flow-sheet design, and membrane selection in membrane gas separation.

Author(s) : XU J.

Type of article: Article

Summary

The paper discusses several ways of improving thermodynamic efficiency membrane separation other than pressure ratio optimization, such as optimal process flow-sheet design and membrane selection, and explains the relationship between the various factors affected by these measures and thermodynamic efficiency. The author showed that a membrane with a higher selectivity (and lower permeance as a consequence) should be used for separation of mixtures with higher concentration of the more permeable component and vice versa. The concept of separation ability was introduced as a tool to relate membrane area to thermodynamic efficiency.
