How to treat acetone waste gas

Acetone exhaust will generally appear in the chemical plant or pharmaceutical industry, mainly arising from the volatility of acetone solvent, because the volatility of acetone is relatively strong, so in the production process will produce sectoral acetone exhaust emissions, greatly polluting the surrounding air, it must be after the appropriate exhaust treatment, and then discharged into the air, how to deal with acetone exhaust? The following with the Everest blue editor to take a look~

Acetone, also called dimethyl ketone, is a colourless transparent liquid, highly soluble in water and methanol, ethanol, ether, pyridine and other organic solvents, as many industries are in use, that is why it will be necessary to select the more appropriate acetone exhaust treatment solution to solve.

For the treatment of acetone exhaust, there are generally the following methods of treatment:

1, water spray purification method: acetone exhaust treatment, acid mist exhaust treatment, alkali mist exhaust treatment and paint exhaust treatment, paint exhaust treatment, organic exhaust treatment of absorption and dissolution, chemical exhaust adsorption, oxidation and reduction, acid and alkali neutralisation has a significant treatment effect;

2, condensation method: the use of acetone exhaust gas of different vapour pressure, through the pressure and temperature adjustment to make acetone oversaturation and coalescence, so that the mixture of acetone air to a high degree of purification, acetone can also be recovered;

3、Absorption method: through the selection of low volatility of the solvent as an absorbent, the use of acetone in the solvent solubility to achieve purification. Absorption method process is simple, the process is not chaotic, high purification efficiency, is currently the more ideal acetone exhaust gas purification technology. Through the wet exhaust gas treatment equipment packing tower, the agent can effectively deal with acetone exhaust gas, simple process;

4, combustion method: divided into direct flame combustion method and catalytic combustion method. It uses direct oxidation and catalytic oxidation to decompose and destroy the organic molecules in the exhaust gas, so that it is born with low-toxicity substances, so as to achieve the purpose of direct emission of volatile organic compounds;

5, adsorption method: the recovery of industrial waste gas acetone is more commonly used in a waste gas purification method, its process is mature, there is a high degree of efficiency. Currently common adsorbents are activated carbon, silica gel substances, etc..
