ABSTRACT:
A process is provided for selectively removing acid gases from a gas mixture by contacting said gas mixture with an anion exchange resin containing quaternary ammonium functionalities and moderately basic counteranions. The absorption process is reversible and the absorbent can be regenerated using an inert gas purge or by applying a vacuum.
