Problems solved by technology

The existing problem is that the heat release of the adsorption reaction is large, especially when the sulfide is high, the heat release is severe, which affects the safety of production; when the water vapor and hydrocarbon content are high, it is easy to wrap the desulfurizer, resulting in a decrease in the effect of the desulfurizer and failure; the air volume is low or the desulfurizer After saturation, ferrous sulfide will be formed. Due to the spontaneous combustion of ferrous sulfide, there is a hidden danger of explosion. Similar explosion accidents have occurred in some enterprises
[0009] Although most of the above methods can be used for the treatment of exhaust gas from acid water tank farms, there is no suitable and optimal treatment method combined with the characteristics of discharge gas from acid water tank farms.

Embodiment Construction

[0024] The method of the present invention will be further explained below in conjunction with the drawings.

[0025] Such as figure 1 As shown, during the exhaust period of the storage tank area, the exhaust gas 1 discharged from the storage tank area first passes through the elastic breathing air chamber 15 (one or several emission reduction measures can be adopted, figure 1 In this case, an elastic breathing chamber is used. After the elastic breathing chamber 15 is full, exhaust gas is discharged to the exhaust gas treatment system. The exhaust gas passes through the first-stage condensation zone 3, the second-stage condensation zone 4 and the third-stage condensation zone 5 in sequence, and all the condensation zones are connected to the refrigeration unit 2. In the primary condensation zone, the condensate 9 is mainly water, which can be further processed. In the secondary and tertiary condensing zones, the condensate 10 is mainly organic volatiles, which are separated an...

Abstract

The invention relates to a method for treating the discharged waste gas of an acid water tank area. The acid water tank area at least comprises an acid water storage tank and is provided with an acid water tank area waste gas discharge reducing system. After the acid water tank area waste gas discharge reducing system is mounted, the waste gas discharge amount of the tank area is reduced, and the waste gas processing is further carried out on the discharged waste gas. A condensing system and an adsorbing system are adopted in the waste gas processing. The acid water tank area waste gas discharge reducing system is one or more of an acid water degasification processing system, an acid water tank temperature control system, an acid water tank pH value control system, an acid water tank liquid level control system and an elastic respiratory gas bin. The method has the characteristics of less gas discharge amount of the acid water tank area, high hydrocarbon recovery rate, no secondary pollution, low energy consumption, high operation safety, and the like.

Description

Technical field [0001] The invention relates to a method for treating exhaust gas discharged from an acid water tank area, in particular to a method for treating exhaust gas discharged from an acid water storage tank area in industries such as oil refining and chemical industry. Background technique [0002] The waste gas discharged from the acidic water storage tank area in the oil refining and chemical industries is an important source of malodorous gas pollution, which contains high concentrations of volatile hydrocarbons, hydrogen sulfide, organic sulfur compounds, ammonia and other pollutants. If effective treatment is not taken The method will cause serious pollution and at the same time cause a lot of waste of resources. [0003] Existing treatment methods for this kind of waste gas include combustion, condensation, biological, adsorption, chemical absorption and combined methods. The choice of treatment technology for malodorous gas treatment can be comprehensively conside...
