Abstract:
1. A method for regenerating a rich amine solution, the method comprising: interacting a process stream comprising an acidic component with a lean amine solution in an absorber; removing at least a portion of the acidic component from the process stream by absorbing the acidic component into the lean amine solution within the absorber, thereby producing a rich amine solution, a reduced acidic component stream, and heat; providing at least one of the process stream and the reduced acidic component stream to at least one heat exchanger, thereby transferring the heat to a heat transfer fluid to produce a heated heat transfer fluid; and regenerating the rich amine solution by heating the rich amine solution in a regenerator to create the lean amine solution and a rich stream of the acidic component, wherein heat from the heated heat transfer fluid is used in the regenerating.
