Abstract

The invention discloses micro emulsion absorption liquid for treating triphenyl organic waste gas. The micro emulsion absorption liquid is prepared from the following raw materials: water, a mixed oilphase, a nonionic surfactant and a cosurfactant. Compared with the prior art, the micro emulsion absorption liquid has the advantages that: the micro emulsion absorption liquid has excellent thermodynamic stable performance, and does not react to generate other substances after absorbing triphenyl; the micro emulsion absorption liquid balances the proportion of the materials, has an HLB value of13.8, and belongs to the O / W water-in-oil type micro emulsion; and through fractioning and recycling, the micro emulsion absorption liquid has absorption efficiency of 80% or higher after being recycled by three times.

Description

technical field [0001] This article relates to a waste gas microemulsion absorption liquid, in particular to a microemulsion absorption liquid for treating "triphenyl" organic waste gas, its preparation method and application. Background technique [0002] "Triphenyl" (benzene, toluene, xylene) as an important chemical raw material or solvent is widely used in pesticide, medicine, fuel, spice production, spray paint, pharmaceutical and other industries. Benzene series such as benzene, toluene, and xylene have strong biological toxicity. If they are discharged into the air, they will not only cause air pollution, but also cause great harm to the human body. [0003] According to a study by Tsinghua University, the VOCs (volatile organic compounds such as benzene, toluene, and xylene) treatment technologies currently used in my country include adsorption, catalytic combustion, biological treatment, and absorption. The absorption method has the advantages of simple equipment a...
