ABSTRACT:
A process is provided for improving the sulphur yield of a sulphur production unit using an acid gas containing H.sub.2 S and wherein said unit is comprised of a sulphur plant with a downstream purification unit. The H.sub.2 S resulting from hydrolysis of COS and CS.sub.2 is almost entirely recovered in the form of sulphur in the purification unit resulting in an improved sulphur output of the overall installation.
