Process and apparatus for carbon dioxide and carbonyl sulfide capture via ion exchange resins

摘要

A process for the reduction of carbon dioxide and carbonyl sulfide from various types of gas emitting sources containing carbon dioxide and/or gas or liquid emitting sources containing carbonyl sulfide, using ion exchange resin.

1. A process for removing carbonyl sulfide from a carbonyl sulfide containing fluid stream, the process comprising:
contacting the carbonyl sulfide containing fluid stream and a benzyl amine-co-polystrene based ion exchange resin, sorbing at least a portion of the carbonyl sulfide from the carbonyl sulfide containing stream by the on exchange resin, thereby forming a carbonyl-sulfide-form ion exchange resin, and desorbing the attached carbonyl sulfide from the carbonyl-sulfide-form ion exchange resin by one of: heat, or heat and vacuum, thereby increasing the capacity of the resin to re-adsorb carbonyl sulfide.
