Chemical plant workshop exhaust gas treatment analysis

At present, the commonly used methods of chemical plant workshop exhaust gas treatment mainly include absorption, adsorption, thermal decomposition, incineration and catalytic combustion. The choice of which waste gas treatment method depends on the physical and chemical properties, concentration, emissions, emission scale and economic value of the waste gas recovery raw materials or by-products. The following with the Everest blue editor to understand:

Chemical plant exhaust gas treatment equipment

Chemical plant workshop waste gas treatment absorption method: in the control of chemical waste gas organic pollution, chemical absorption method using a variety of methods.
(1) water absorption containing phthalic anhydride, maleic anhydride, benzoic acid, naphthoquinone exhaust gas, naphthalene or o-xylene as raw material for the production of phthalic anhydride and so on.
(2) water and alkali solution absorption chlorohydrin production in the tail gas of sodium hypochlorite tower (acid component) recovery of propane> sulfonation method phenol production containing phenol exhaust gas using alkali rotation method absorption, acidification of the absorbing solution recovery of phenol; synthetic resin device containing formaldehyde tail gas is absorbed by water.

Chemical plant workshop exhaust gas treatment adsorption method: can be used to purify the chemical production emissions containing solvents or organic waste gas, such as paint, plastics, rubber and so on. Activated carbon adsorption tower is generally used. Activated carbon adsorption method is a commonly used exhaust gas purification method in vinyl chloride and carbon tetrachloride production. It is widely used in paint, paint production, coating, printing and other industries. Because of the high cost of activated carbon treatment and the poor quality of desorption and recovery in the sector, the activated carbon adsorption method is only suitable for the treatment of high-concentration organic waste gas in the sector.

Chemical plant workshop exhaust gas treatment incineration method: organic chemical production of organic pollutants in the exhaust gas or malodorous substances can be directly burned or catalytic combustion method for treatment. Requirements for combustion must be complete, otherwise the formation of intermediate products in the incineration process may be more dangerous than the original pollutants. In order to make the combustion complete, it is necessary to grasp three important parameters: combustion time, temperature and turbulence.
