Description

technical field [0001] The invention relates to the technical field of sulfur compounds, in particular to a device for separating hydrogen sulfide, a by-product of carbon disulfide, using plasma. Background technique [0002] Carbon disulfide is an important chemical raw material, which is generally synthesized by the reaction of carbonaceous substances and sulfur vapor at high temperature. It is mainly used in the production of man-made fibers, cellophane, pesticides, carbon tetrachloride, rubber, metallurgical beneficiation and petroleum smelting. At present, it is mainly used as a solvent and a raw material for the synthesis of some fine chemical products, and can also be used as an insecticide and a grain fumigant. Production of carbon disulfide At present, most manufacturers at home and abroad adopt the production method with sulfur and methane as raw materials. [0003] However, the devices currently on the market for separating hydrogen sulfide, a by-product of carb...

AI Technical Summary

Problems solved by technology

Using sulfur and methane (or natural gas) as raw materials to produce carbon disulfide has a large amount of hydrogen sulfide gas as a by-product. For every ton of carbon disulfide produced by the natural gas method, about 900 kg of hydrogen sulfide gas is produced at the same time. The investment cost of hydrogen sulfide recycling and tail gas treatment after recovery is large. , The material requirements of the equipment are high and the service life is short, and a large amount of methane (or natural gas) must be burned during the reaction. The ratio of reaction raw gas to fuel gas is 6:5, and the process risk factor is high, but this method has good working conditions, Features of high labor productivity, small equipment footprint and high degree of automation
