摘要: One exemplary embodiment can be a process for treating a tail gas stream from a sulfur recovery zone. Generally, the process includes passing the tail gas stream through, in sequence, a hydrogenation zone, a quench zone, and an acid gas removal zone using a solvent. The solvent can include at least one of a dimethyl ether of polyethylene glycol, a N-methyl pyrrolidone, a N-formyl morpholine, a N-acetyl morpholine, a tetrahydro-1,4-oxazine, and a mixture comprising diisopropanolamine and tetrahydrothiophene-1,1-dioxide.
