Abstract: The invention provides a system for removing an acid gas from syngas with enhanced heat recovery, the system including an acid gas absorber containing a solvent and having an inlet positioned to receive a syngas stream, the acid gas absorber producing an acid gas enriched solvent effluent; a first heat exchanger positioned to exchange heat between the syngas stream upstream of the acid gas absorber and the acid gas enriched solvent effluent; and an acid gas stripper positioned to receive the acid gas enriched solvent effluent from the first heat exchanger, the acid gas stripper producing a lean solvent effluent having reduced acid gas content. The invention also provides a method for removing an acid gas from syngas with enhanced heat recovery, which involves heating an acid gas enriched solvent effluent through heat exchange with a syngas stream upstream of an acid gas absorber.
