Process for recovering hydrogen and elemental sulfur from hydrogen sulfide and/or mercaptans-containing gases

Patent ·
OSTI ID:5245859
A process is claimed for removing hydrogen sulfide and/or mercaptans from hydrogen sulfide and/or mercaptans-containing gases using aqueous iodine slurry and/or solution to recover elemental sulfur as one product and to generate hydriodic acid which is dehydrated, pressurized, and decomposed into iodine for recycling and into hydrogen for recovering as another product.
