Abstract
A hybrid physical-chemical absorbent process using the interrelation between a physical solvent and a H.sub.2 S selective chemical solvent for removal of CO.sub.2 and sulfur containing compounds, principally H.sub.2 S from a mixed gas stream. This process is especially useful in processes such as coal gasification where the incoming stream to the acid gas removal process is at about 1100 psia, 70.degree. F., contains about 15 to 40 mole percent CO.sub.2 at a mole ratio of CO.sub.2 /H.sub.2 S of about 25 to 50. In such cases the product stream contains less than 1 ppm sulfur and less than 3 mole percent CO.sub.2 which is suitable for production of substitute natural gas while the CO.sub.2 atmospheric effluent contains less than 7 ppm sulfur.
