Methods and systems for emissions control in solvent-based CO2 capture processes using CO2
Abstract
A method with corresponding systems for reducing emission of amines to the atmosphere. The method includes a a) introducing a gas containing CO2 into an absorber; b) flowing the flue gas through an absorber having an absorbent with a water-lean solution having less than 50% water and one or more amines, with the absorbent capturing the CO2 and forming a reduced CO2 content gas having a baseline CO2 content; and c) washing the reduced CO2 content gas in a wash column with a wash solution comprising carbonic acid formed by addition of gaseous CO2 into the wash solution. In this method, the washing removes the amines from the reduced CO2 content gas and produces a reduced amine content gas exiting from the wash column.
