Low-energy process recovers CO/sub 2/
This paper discusses processes for removal of acid gas constituents from natural gas, which include the alkanolamine processes such as monethanolamine (MEA) and DEA, but also physical solvent processes such as Selexol, Sepasolv MPE, Rectisol, and Purisol. It points out that a key advantage of physical solvent processes is that the solution can be regenerated by flashing rather than by the steam stripping used in the conventional alkanolamine processes. A single-stage and two-stage activated MDEA process developed in West Germany for treating high-pressure natural gas is described. The one or two-stage process is also applicable to high pressure natural gas streams containing both H/sub 2/S and CO/sub 2/.
