Abstract
The present disclosure describes a process for separating at least a first gas component and a second gas component by contacting a gas stream comprising the first and second gas components with a carbon molecular sieve (CMS) membrane under aggressive gas separation conditions in which the partial pressure of the selectively sorbed gas component in the gas stream is high. Despite the high partial pressure of the sorbed gas component, the selectivity of the carbon molecular sieve membrane is not substantially reduced by plasticization or saturation. In some embodiments, the aggressive gas separation process may include contacting a gas stream at supercritical conditions with a CMS membrane to separate at least first and second gas components. The process may be useful for, among other things, the separation of CO₂ from a natural gas stream.
