How can ethyl acetate in the exhaust gas of vacuum pumps be recovered and reused?
Thread Content
When ethyl acetate is used as a solvent and vacuum concentration is employed, although the cooling area is increased to lower the temperature of the brine, ethyl acetate vapor still escapes from the vacuum pump exhaust. This results in a low solvent recovery rate, higher costs, and the direct emission of these waste gases into the environment without any treatment. I would like to ask everyone here: are there any ways to recover ethyl acetate from exhaust gases? I found that for the treatment of such waste gases, there is the method of adsorption and recovery using activated carbon fibers. I wonder what the investment cost for the equipment is? Are there any other recycling methods? It is said that chlorinated paraffins can absorb ethyl acetate gas?
Activated carbon adsorption should work; it requires little investment, and once the emission requirements are met, the emissions can be released into the atmosphere!
Hello, what is the volume of your exhaust gases? The ethyl acetate-containing exhaust gases can be recovered using an absorption device; the recovered ester can then be purified and reused. For more details, please contact QQ451094557
