Problems solved by technology

[0004] The alkali solution absorbent used in the odor control device has a low removal rate, a single type of removal, and the exhaust gas cannot be discharged up to the standard. At present, the refining and chemical enterprises adopt alkali absorption treatment process for the odor pollution gas, but the existing alkali liquid absorption desulfurization has a removal rate. Low, the hydrogen sulfide removal rate is only 70%, the desulfurization species is single, and dimethyl disulfide cannot be removed. After dehydrogen sulfide, the product sodium sulfide is unstable, and it is easy to cause secondary pollution during waste residue treatment
In addition, the alkali absorbent will corrode the equipment and affect the utilization rate of the equipment, etc.

Embodiment Construction

[0013] A chemical absorbent consisting of the following components by weight:

[0014] Strong base 12%-18%, oxidant 6%, active agent 0.25%-0.45%, corrosion inhibitor 0.06%-1.8%, pour point depressant 0.06%-1.8%, desulfurizer 0.06%-7%, catalyst 0.06%- 3.8%, water 65%-75%; the strong base is sodium hydroxide, and the content of sodium hydroxide is 16%; the oxidant is sodium hypochlorite, and the content of sodium hypochlorite is 6%; the active agent is isopropanol The content of amine, isopropanolamine is 0.35%; at least 50% of the sodium hydroxide, sodium hypochlorite, and isopropanolamine have a particle size of less than 100 microns by weight.

[0015] The chemical absorbent in the present invention is composed of strong base, oxidant, catalyst, activator, corrosion inhibitor, pour point depressant, desulfurizer and water. The oxidizing agent is preferably sodium hypochlorite, and various hypochlorites with strong oxidizing properties in other alkaline environments can also ...

Abstract

The invention discloses a chemical absorbent, which consists of the following components by weight: 12 to 18 percent of strong base, 6 percent of oxidant, 0.25 to 0.45 percent of active agent, 0.06 to 1.8 percent of corrosion inhibitor, 0.06 to 1.8 percent of pour point depressant, 0.06 to 7 percent of desulfurizing agent, 0.06 to 3.8 percent of catalyst, and 65 to 75 percent of water. The chemical absorbent solves the problem that the soda ash liquid has low removal rate of hydrogen sulfide in the prior art, and improves the absorption rate of sulfur compounds in the tail gas; the chemical absorbent overcomes singleness of the conventional desulfuration technology on the sulfur compound, and can remove multiple organic sulfurs; the waste sodium sulfide residue generated after the treatment is stable and is not easily decomposed so as to avoid secondary pollution; and the service life of the chemical absorbent is longer than that of the conventional absorbent, and the chemical absorbent has high reaction speed for removing the sulfur components.

Description

technical field [0001] The invention relates to a chemical product, in particular to a chemical absorbent. Background technique [0002] Air is a necessary condition for human survival. Adults need to inhale more than ten kilograms of air every day on average, which is several times more than the demand for food and water. Whether the air we inhale is fresh and clean is closely related to each of us. Polluted air entering the human body can cause respiratory, cardiovascular, nervous and other system diseases or other diseases. Odor pollution is a kind of sensory pollution that causes unpleasant feelings through people's sense of smell, and even affects human health. Volatile odorous molecules that are vicious and have a low olfactory threshold escape into the atmosphere, stimulating people's sense of smell and causing strong discomfort, dyspnea, anorexia, nausea, decreased digestive function, irritability, insomnia, and reduced work efficiency. Most of the foul-smelling g...
