FRP gas hood is suitable for use in burning method to control odor of sewage in refinery
Up to now, there have been many studies on deodorization technology, which can be divided into physical deodorization method, chemical method and living material deodorization method. Various disposal methods have their own advantages and disadvantages. Widely used is the deodorization method of living material, and the deodorization method of living material has obtained a large number of promotion and discussion applications because of better disposal effect and lower energy consumption. The burning method is better than the living material method. The deodorizing effect is better and the disposal is more thorough. However, in the burning method, there is a need to waste a large amount of burning materials, and there is a danger of fire and explosion in the burning process, and the burning method is not deepened. Research and promotion applications. Under the strong support of Sinopec Shijiazhuang refining and chemical sub-enterprise, the guts innovation and experiment were carried out on the burning method. It was proposed that the odor in the sewage disposal unit was put together and then entered into the sulfur recovery unit to be burned. The law governs the odor scheme, and this paper discusses a key issue in the process of burning the law. 1 odor component and provenance analysis From the final result of odor monitoring in a refinery wastewater treatment plant to the disposal unit, it is known that the sewage treatment plant distributes about 152 kinds of gases, and the main source of the odor is hydrogen sulfide and methyl sulfide. Alcohol, dimethyl sulfide, formaldehyde, trimethylamine, and the like.
