Removal of hydrogen sulfide from gas by supergravity method
In response to the characteristics of the large volume, low efficiency, large liquid circulation volume, and high operating costs of the desulfurization tower in the wet oxidation desulfurization process, the high gravity rotating packed bed is used as the absorption equipment to form the high gravity wet oxidation technology for removing hydrogen sulfide. The advantages of the high gravity wet process for removing hydrogen sulfide are as follows:
(1) The hydrogen sulfide removal rate is over 95%;
(2) The gas-liquid ratio of desulfurization is greater than 100;
(3) Gas phase pressure drop less than 1000Pa;
(4) The equipment volume is 1/10 of a traditional tower;
(5) The investment and operating costs are 2/3 of the tower desulfurization method;
(6) Transforming hydrogen sulfide into sulfur, turning waste into treasure, without secondary pollution.
This technology has been successfully applied to engineering projects such as desulfurization of furnace gas in Guangxi Huayin Aluminum Industry, desulfurization of sulfur-containing CO ₂ tail gas generated by low-temperature methanol washing desorption process in Tianji Group, desulfurization of coke oven gas in Taiyuan Dongsheng Coking Plant, Hebei Huida Ceramic Group, and ammonia purification of tail gas hydrogen sulfide in the manganese oxide industry in Pingwu Manganese Industry, Sichuan, achieving good results. This technology can be widely applied to the removal of various sulfur-containing tail gases and hydrogen sulfide, such as natural gas, refinery gas, coalbed methane, synthesis gas, coke oven gas, etc; It can be widely applied to pressurized desulfurization systems such as natural gas and shift gas, with broad application prospects
