FIELD: chemistry.
SUBSTANCE: system is intended for removal of carbon dioxide (CO2) from gas flow by bringing gas flow in contact with circulating flow of ammoniated solution in such a way that CO2 is removed from gas flow by flow of ammoniated solution. Method of removing non-volatile compounds from circulating flow of ammoniated solution includes introduction of part of circulating flow of ammoniated solution into device of gas-liquid separation; separation of introduced ammoniated solution into ammonia-enriched gas phase and liquid phase, containing non-volatile compounds; and re-introduction of ammonia-enriched gas phase into circulating flow of ammoniated solution.
EFFECT: invention makes it possible to improve absorption of carbon dioxide by ammoniated solution.
