Abstract
Systems for regenerating an absorbent solution include steam produced by a boiler; a set of pressure turbines fluidly coupled to the boiler for receiving the steam, wherein the set of pressure turbines comprises a high pressure turbine, a medium pressure turbine and a low pressure turbine; and a regenerating system comprising a regenerator for regenerating a rich and/or semi-rich absorbent solution to form a lean absorbent solution in fluid communication with a reboiler, the regenerating system fluidly coupled to the set of pressure turbines, wherein steam from the low pressure turbine provides a heat source for preheating the rich or the semi-rich absorbent solution fed to the regenerator. Also disclosed are processes of use.
