Liquid Sorbent-Enhanced Ammonia Production

Research output: Patent

Abstract

The present disclosure relates to a method that includes, in a first zone, contacting an ammonia-rich gas comprising ammonia with an ammonia-lean liquid sorbent resulting in the reversible transfer of at least a portion of the ammonia from the ammonia-rich gas to the ammonia-lean liquid sorbent, thereby forming an ammonia-rich liquid sorbent and an ammonia-lean gas and, in a second zone, removing at least a portion of the ammonia from the ammonia-rich liquid sorbent to form gaseous ammonia and regenerate the ammonia-lean liquid sorbent.
