METHOD AND INSTALLATION FOR NEUTRALISATION OF GAS MIXTURE ACIDITY Russian patent published in 2014 - IPC B01D53/14 

FIELD: chemistry.

SUBSTANCE: claimed are method and installation for neutralisation of gas mixture acidity. Method and installation include realisation of contact of gas mixture with absorbent in absorber. Absorbent contains bearing phase and organic phase, which does not mix with bearing phase; providing possibility of absorption of acidic gas by organic phase and conversion of acidic gas into absorbed acidic gas in order to convert absorbent into gas-rich absorbent, and to convert gas mixture into purified gas mixture. Providing possibility of transition of absorbed acidic gas into bearing phase in order to form first gas-poor phase and gas-rich phase in gas-rich absorbent; supply of gas-rich absorbent into separator in order to separate first gas-poor phase from gas-rich phase. Cyclic return of separated first gas-poor phase back into absorber; supply of gas-rich phase into regenerator in order to obtain acidic gas and second gas-poor phase; and cyclic return of second gas-poor phase back into absorber.

EFFECT: invention makes it possible to reduce general consumption of energy for carrying out operation of acidity neutralisation.
