Abstract
Official abstract text for this publication.
Disclosed are methods of obtaining carbon dioxide from a CO 2 -containing gas mixture. The methods combine the benefits of gas membrane separation with cryogenic temperatures.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of obtaining carbon dioxide from a CO 2 -containing gas mixture, said method comprising the steps of: flowing a CO 2 -containing gas mixture, at a temperature which is in a range of from −20 to −50° C., into a gas separation membrane module made of a polymeric material to produce a carbon dioxide-rich stream and a carbon dioxide-lean stream, wherein the polymeric material is a polyimide polymer or copolymer having repeating units of formula (I) and/…
