Process For Separation Of Gases

Patent No. EP2588217 (titled "Process For Separation Of Gases") was filed by Evonik Fibres on May 26, 2011. The application was issued on Feb 22, 2017.

A device and method for separating gas mixtures into two fractions each of increased purity. The method involves concatenating multiple gas separation membrane modules in a specific order to improve purity and yield compared to single or two-stage interconnections. The concatenated modules have features like recirculation, compression, and internally stepped configurations. This allows higher methane purities in the permeate stream and better retentate yield compared to traditional interconnections.
