Abstract
A high temperature absorption process for bulk recovery of CO.sub.2 comprises contacting a gaseous mixture containing CO.sub.2, H.sub.2 S, and natural gas with C.sub.3 and heavier components and having a high and variable CO.sub.2 loading, with an amine absorbent solution at a temperature above 220.degree. F. The amine absorbent solution is continuously regenerated in a multiple section flashing so as to reduce the energy requirements for regeneration and thereby making the process more suitable for bulk recovery of CO.sub.2 from gas streams associated with enhanced oil recovery projects employing CO.sub.2 for miscible flood of oil reservoirs.
