Embodiment Construction

[0018] Such as figure 1 As shown, the malodorous gas 3 uses its own pressure to enter the lower part of the gas-liquid separator 4, and the gas and liquid are separated in the gas-liquid separator 4. The separated gas comes out of the upper part of the gas-liquid separator 4 and enters the supergravity rotation The bottom of bed 1 reacts with solvent A under the effect of bed atomization, and the volume ratio of solvent A to the malodorous gas entering the supergravity rotating bed 1 is 4-20l / m 3 This is the first-level absorption. The reacted liquid phase enters the A solvent tank 6 and contacts with the solvent A countercurrently. After treatment, it returns to the supergravity rotating bed 1 under the action of the solvent A circulation pump 7 for recycling, and is treated by the solvent A The latter gas enters the packed absorption tower 2 with a residence time of 1 to 3 seconds, which can ensure the absorption effect of low-concentration gas. The liquid phase in the packed a...

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