ABSTRACT:
An apparatus and process for the removal of sulfur, in the form of hydrogen sulfide (H.sub.2 S), from gas, such as natural gas or industrial gas streams, in which the sulfur is removed and separated in the form of particulate elemental sulfur. The apparatus and process are advantageously configured so as to maintain control over the development of undesired concentrations of particulate sulfur in the precipitation catalyst solution with which the sulfur is separated from the gas stream.
