Treatment method of chlorine-containing volatile organic compound waste gas

Abstract

The invention relates to a treatment method of chlorine-containing volatile organic compound waste gas, which comprises the following steps: the chlorine-containing volatile organic compound waste gas is contacted with an absorbent, the absorbent is a choline chloride and polyhydric alcohol composite solvent, regeneration is carried out after absorption balance, and the regenerated absorbent is recycled. The choline chloride and polyhydric alcohol composite solvent is used as the chlorine-containing organic matter waste gas absorbent, chlorine-containing VOCs can be rapidly and effectively absorbed, and the absorption efficiency is high.

Description

technical field

[0001] The invention belongs to the field of gas absorption, and in particular relates to a treatment method for chlorine-containing volatile organic compound waste gas. Background technique

[0002] Chlorinated volatile organic compounds (chlorinated VOCs) are a class of pollutants commonly found in environmental media, including chlorinated alkanes, chlorinated olefins, and chlorinated aromatics. Generally speaking, these substances mainly come from petrochemical, printing, pharmaceutical and other industries. The volatilization of chlorine-containing VOCs will cause air pollution and are considered as persistent pollutants. Most of them are insoluble in water and difficult to be biodegraded in the environment. , the chlorine-containing VOCs emitted into the atmosphere will destroy the ozone layer, form photochemical smog and global warming, and have "three effects" on the human body. Therefore, chlorine-containing VOCs are restricted by strict laws and reg...
