Abstract
A recovery plant for recovery of a gaseous component, such as carbon dioxide, from a process gas, such as the exhaust from a combustion turbine, has an absorber ( ) employing a lean solvent ( ) in an upper section of the absorber and a semi-lean solvent ( ) in a lower section of the absorber. A regenerator ( ) extracts the gaseous component from the rich solvent ( ) thereby producing a regenerated lean solvent ( ) and a semi-lean solvent ( ). A solvent flow control element ( ) combines at least a part of the semi-rich solvent ( ) from the upper section of the absorber with the semi-lean solvent ( ) from the regenerator to form a mixed solvent ( ), and a cooler ( ) cools the mixed solvent that is subsequently fed into the lower section of the absorber ( ). By cooling the mixed solvent prior to entry into the absorber, the thermal energy required to remove the carbon dioxide from the exhaust gas can be reduced.
