    Abstract: An improved process for the removal and recovery of sulfur from a sour hydrocarbon stream is provided. The process includes contacting a sour hydrocarbon stream that includes hydrogen sulfide and carbon dioxide with a lean absorbent to produce a rich absorbent stream. The rich absorbent stream is separated and the recovered acid gas is contacted with a second absorbent to produce a second rich absorbent stream. A portion of the second rich absorbent is recycled to the separation step. A second portion of the second rich absorbent is separated to produce an acid gas product stream. Recycling a portion of the second rich absorbent to the first separation step shifts the equilibrium of the process, resulting in an acid gas product stream having an increased hydrogen sulfide:carbon dioxide ratio.
