APPARATUS FOR AND METHOD OF REMOVING ACIDIC GAS FROM A GASEOUS STREAM AND REGENERATING AN ABSORBENT SOLUTION

摘要

An apparatus for and method of removing acidic gas from a gaseous stream and regenerating an aqueous solution allows for the recovery of waste heat of stripping steam and more economical regeneration of the aqueous solution. In at least one embodiment, one or more rich solvent bypasses combine with a rich solvent heat exchanger to recover waste heat. In another embodiment, the apparatus and method include one or more rich solvent bypasses and a heater positioned upstream of the stripper to more economically regenerate an aqueous solution.
