Process for hydrogen sulfide production

Abstract From the Canadian patent

Abstract of the Invention, A hydrocarbon is partially oxidized in the presence of steam and oxygen in a high temperature reducing flame zone to which sulfur is added in excess of the quantity of hydrogen and carbon monoxide formed to generate a second flame zone. The gas stream is rapidly cooled to prevent further reactions, then further cooled to condense sulfur to the extent of providing unreacted hydrogen and carbon monoxide in a molar excess over the residual sulfur present in the gas stream. The resultant gas stream is passed to a catalytic conversion zone where residual sulfur and carbonyl sulfide are converted to hydrogen sulfide. A formed gas stream free of sulfur and sulfur dioxide …
