METHOD AND INSTALLATION FOR PURIFYING WASTE GASES Russian patent published in 2017 - IPC B01D53/14 F23G7/07 

FIELD: chemistry.

SUBSTANCE: installation contains a liquid absorber designed to remove organic substances from the treated gases due to absorption and condensation; a heat exchanger connected to the liquid absorber in the liquid phase and configured to cool the liquid sorbent circulating between the liquid absorber and the heat exchanger; a refrigeration unit connected to the heat exchanger and configured to supply the heat exchanger with a refrigerant circulating between the refrigeration unit and the heat exchanger to cool the liquid sorbent; a catalytic afterburner connected to the liquid absorber over the gas phase and configured to oxidise organic substances in the treated gases supplied from the liquid absorber; a supercharger connected in the gas phase with the liquid absorber and the catalytic afterburner and configured to force atmospheric air into a stream of the treated gases between the liquid absorber and the catalytic afterburner to reduce concentration of organic substances in the treated gases.

EFFECT: invention allows to expand the value range of the gas volume supplied for purification per unit time and concentration of organic compounds at the inlet.
