PROCESS FOR CATALYTIC CRACKING ASSOCIATED WITH AMINE TREATMENT UNIT WITH IMPROVED CO2 BALANCE Russian patent published in 2017 - IPC B01D53/14 C10G11/18 F01K23/06 G06Q30/06 

FIELD: gas industry.

SUBSTANCE: invention relates to an integrated method of trapping CO₂, emitted with exhaust gases, coming out of a regeneration zone of a catalytic cracking (FCC) unit, which unit treats a vacuum distillate or atmospheric residue type hydrocarbon cut, by subjecting said fumes to amine treatment in an amine treatment unit (AMN) to eliminate CO₂ therefrom, producing HP steam by cooling fumes exiting from regeneration zone, and using in at least one counter-pressure turbine, which actuates not exclusively: a) either an air blower to feed regeneration air (MAB) of FCC unit; b) or cracked gas compressor (WGC); wherein formed BP is used for regeneration of amine in amine treatment unit (AMN), and excess steam HP and BP are recalculated in reducing CO₂ emissions.

EFFECT: method improves balance of CO₂.
