DEFINITION

Classification: 423/576.4

By reacting gaseous feed stream with liquid aqueous mixture:

(under subclass 573.1) Subject matter in which a hydrogen sulfide-containing feed gas is contacted with a liquid which contains a significant amount of water, elemental sulfur being formed in such mixture.

(1) Note. A "significant" amount of water is taken to mean more than commercial impurities or that provided by water of reaction.
