Title: Method and system for treatment of a gas stream that contains carbon dioxide

Abstract

A method for separating carbon dioxide (CO2) from a gas stream is disclosed, in which the gas stream is reacted with a lean aminosilicone solvent in an absorber, resulting in a rich aminosilicone solvent that is then treated in a desorber to release the CO2 and regenerate lean aminosilicone solvent in a desorption reaction. The regenerated solvent is directed into a steam-producing, indirect heat exchanger that is configured to supply steam to the desorber at a temperature high enough to augment the desorption reaction. Also, selected amounts of make-up water are added to the rich aminosilicone solvent at one or more process locations between the absorber and the desorber, to lower the viscosity of the solvent and to lower the temperature required for the desorption reaction.
