SELF-CONCENTRATING ABSORBENT FOR SEPARATION OF ACIDIC GAS Russian patent published in 2014 - IPC B01D53/40 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of a gas mixture acidity neutralisation with the application of a self-concentrating absorbent. The method and system of neutralising acidity of the gas mixture, containing acidic gas, includes: bringing the gas mixture in contact with an absorbent in an absorption installation, realisation of the acidic gas absorption by the absorbent in order to obtain a phase of a concentrated amine, separation of the obtained phase of the concentrated amine from the remaining part of the absorbent; supply of the remaining part of the absorbent back into the absorption installation; supply of the phase of the concentrated amine into a regeneration installation and supply of the regenerated concentrated amine back into the absorption installation.

EFFECT: increased rate of the acidic gas absorption from the gas mixture.
