AN AMMONIA STRIPPER FOR A CARBON CAPTURE SYSTEM FOR REDUCTION OF ENERGY CONSUMPTION

摘要

A carbon capture system, such as a chilled ammonia process, is provided that includes with a cooling system, a carbon dioxide absorption system and an ammonia absorption system. The ammonia absorption system includes an absorber column to receive carbon dioxide lean gas stream having ammonia and to receive an absorbent, wherein the absorbent absorbs ammonia from the carbon dioxide lean gas stream to provide an ammonia reduced gas stream and an ammonia rich absorbent. Further, an ammonia stripper is provided to receive the ammonia rich absorbent and to receive a portion of the gas stream, wherein the gas stream flows through the ammonia stripper to heat the ammonia rich absorbent to release the ammonia therefrom and provide an ammonia rich gas stream and an ammonia reduced absorbent.
