Embodiment Construction

[0018] As shown in Figure 1, the malodorous gas 3 enters the lower part of the gas-liquid separator 4 by its own pressure, and the separation of gas and liquid is realized in the gas-liquid separator 4, and the separated gas comes out from the upper part of the gas-liquid separator 4 and enters The bottom of the high-gravity rotating bed 1 reacts with solvent A under the atomization of the bed body, and the volume ratio of solvent A to the malodorous gas entering the high-gravity rotating bed 1 is 4 to 20 l / m 3 , this is first-order absorption, the liquid phase after the reaction enters the A solvent tank 6, contacts with the solvent A countercurrently, and returns to the high-gravity rotating bed 1 under the action of the solvent A circulation pump 7 after treatment for recycling, and is treated with the solvent A The final gas enters the packed absorption tower 2, and the residence time is 1 to 3 seconds, which can ensure the absorption effect of the low-concentration gas. Th...

Abstract

The invention discloses a malodorous gas treatment integrated process, which solves the pollution problem of malodorous gas with high concentration, high output and complicated ingredients discharged in the oil refining chemical field. The malodorous gas treatment integrated process adopts a hypergravity revolving bed, a packed absorption tower, and two absorbents for multistage absorption of malodorous gas. The malodorous gas treatment integrated process is safe and equipment consumes little power when running.

Description

technical field [0001] The invention belongs to the field of gas treatment and relates to a combined process for treatment of malodorous gas in oil refining and chemical industries. Background technique [0002] In the petroleum refining process, a large amount of hydrogen sulfide, organic sulfur, ammonia and other odorous substances will be produced in the process of crude oil catalytic cracking, coking and sewage treatment. These odorous substances are discharged in the process of production, storage and transportation. , volatilization, leakage and other ways are directly or indirectly discharged into the atmosphere, causing varying degrees of pollution to the surrounding environment. [0003] At present, the commonly used traditional methods for treating malodorous gases are: washing method, cooling method, adsorption method, high-energy ion method, biological method, chemical absorption method, oxidation method and combustion method. Water washing method has low absorp...
