Investigation of Membrane Technology in Gas Separation Process

摘要

In separation of gases, membranes offer the greatest potential. In interaction with a membrane, a high degree of permeability coupled with a large selectivity of a specific gaseous species ensures superior performances in the gas processing industry. Economically, the advantage of membrane separation technology is immense. The separation of natural gas by thin barriers termed as membranes is a dynamic and rapidly growing field, and it has been proven to be technically and economically superior to other emerging technologies. This superiority is due to certain advantages which membrane technology benefits from, including low capital investment, low weight, and space requirement and high process flexibility. In the past ten years, the membrane gas separation technology has advanced greatly and can now be regarded as a competitive industrial gas separation method. The benefits of "Membrane Technology" also include higher recovery of the desired gaseous effluent that can be reused for multiple purposes. This article discusses various experimental and analytical models related to current membrane technologies.
