Background
The tail gas generated from the refining desulfurization and sweetening process of liquefied gas is a mixed gas composed of oxygen, nitrogen, combustible gas, organic sulfide, etc. Wherein: oxygen and nitrogen mainly come from excess oxidizing air introduced into the regeneration tower and are discharged from the top of the regeneration oxidation tower together with hydrocarbons carried by the alkali liquor into tail gas; the combustible gas mainly comes from light hydrocarbon carried by regenerated alkali-rich liquid or light hydrocarbon in an extraction solvent (disulfide is separated from common hydrogenated naphtha), mainly comprises propylene, propane, C4 olefin and C4 alkane, and has the volume fraction of 6-35%, and in addition, the volume fraction of oxygen is 10-21%; the main components of the disulfide are dimethyl disulfide and diethyl disulfide, the boiling point of the disulfide is 109 to 120 ℃, the polarity of the disulfide is very small, and the disulfide has strong volatility under large air volume and high temperature (45 to 65 ℃). Therefore, even if the explosion limit of the sweetening tail gas is controlled, there is a safety risk in both the burning method and the sealed discharge torch method. Because volatile organic compounds and malodorous substances still exist in the tail gas, if the tail gas is directly discharged without being treated, peculiar smell can be generated, the surrounding environment is polluted, and a series of environmental protection problems that the emission concentration of the odor and the non-methane total hydrocarbon does not reach the standard and the like are caused. If the sulfur content in the tail gas is high, the SO2 emission of the tail gas of the boiler or the process heating furnace can exceed the standard. Combustible gas and sulfide exist in the mercaptan removal tail gas, and the composition is complex, so that the tail gas treatment difficulty is increased.
