Abstract

The invention provides a storage tank breathing waste-gas desulfurization deodorizing technique which aims at the offensive odor of sulfur-bearing waste gas (which has a great impact on the environment and human health) produced when the material in sewage tanks, slop oil tanks, oil product tanks and the like in the oil refinery are handled. The technique is realized in a way that: the exhaust gas is desulfurized at -10-100 DEG C under normal pressure by using a DHS-1 H2S fine desulfurizer and an EHC-6 thiol fine desulfurizer, which are produced by Hubei Huabang Chemical Co. Ltd., so that the content of H2S is lower than 0.1 ppm, the content of RSH is lower than 1 ppm, and the waste gas does not have obvious odor and conforms to the emission standard for odor pollutants in China. The technique of the invention has the advantages of high safety and reliability, low equipment investment and operating cost, high handling capacity, and no secondary pollution or pollution transfer.

Description

technical field [0001] The invention relates to fine removal of H at room temperature for breathing waste gas in storage tanks 2 S, RSH and other organic and inorganic sulfide methods. Background technique [0002] With the increase of high-sulfur crude oil processing and the improvement of people's environmental requirements, more and more attention has been paid to the control of odor pollution in refineries. [0003] Respiratory exhaust gas emissions from sewage tanks, waste oil tanks, and oil product tanks in refineries are one of the main sources of odor pollution in refineries. The sulfur compounds in the exhaust gas are mainly H 2 S, RSH, etc. Most of these sulfides are malodorous substances. If they are not treated, they will cause great harm to the surrounding environment and human health. [0004] The sewage tank of Sinopec Yangzi Branch is mainly used to store the waste water generated in the production process of the factory, and a large amount of waste gas wi...
