Patent ID: 8398748

Claim:
A plant comprising: A solvent regenerator having a upper section and a lower section; wherein the upper section has a first rich solvent inlet that is configured to provide a rich solvent reflux, and a second rich solvent inlet that is configured to provide a heated rich solvent regenerator feed; wherein the lower section is configured to produce a lean solvent from both the rich solvent reflux and the heated rich solvent regenerator feed; a heater operationally coupled to the regenerator and configured to heat a portion of a rich solvent to thereby provide the heated rich solvent regenerator feed; a second regenerator that is configured to receive a portion of the lean solvent from the lower section of the solvent regenerator and to produce a steam-containing overhead product and an ultra-lean solvent from the lean solvent; wherein the second regenerator is coupled to the solvent regenerator such as to deliver the steam-containing overhead product to solvent regenerator to thereby provide at least a portion of the stripping steam required in the solvent regenerator; and an absorber having an upper section and a lower section, wherein absorber is configured to receive the ultra-lean solvent from the second regenerator and the lean solvent from the solvent regenerator in the respective upper and lower sections.
