[Abstract]:At present, H _ 2S in industrial gaseous pollutants can cause corrosion of chemical equipment, poisoning and failure of chemical catalyst, increase production cost and decrease product quality.If it is discharged directly into the atmosphere without treatment, the toxic and harmful waste gas will pose a serious threat to human health and the safety of ecological environment because of its special toxicity.The research and development of high-efficiency H 2 S removal technology has become the focus of attention all over the world.The research indicates that the sulfur should be treated and removed in the crude oil processing process from many aspects, such as petrochemical process, natural gas processing process, oil product quality, safety and environmental protection control and so on.The LOCAT sulfur recovery technology, which is a wet oxidation technology of hydrogen sulfide, is analyzed and studied in this paper.The desulfurization efficiency of natural gas, petroleum tail gas, shale retort gas and syngas is as high as 99.99%.It uses a patent catalyst (iron ion complex liquid catalyst) developed by Merichem Company in the United States, which absorbs self-solvent regeneration unit at room temperature and low pressure.The H _ 2S gas produced by the acid water vapor bill of lading element was directly converted into monomer sulfur in the special reaction vessel and the pure sulfur was separated by vacuum filtration system.The purified tail gas (containing ammonia) is sent to the tail gas incineration part. The purified tail gas entering the tail gas incineration is burned through the incinerator to decompose the ammonia contained in the tail gas.The high temperature flue gas from the incinerator contains a lot of heat energy. After the heat is recovered from the waste heat boiler, the temperature drops to 350 鈩，
