METHOD OF DRYING OF WET GAS FLOW ENRICHED WITH CO2, FROM METHOD OF OXYGEN BURNING Russian patent published in 2015 - IPC B01D53/26 

FIELD: heating.

SUBSTANCE: method of drying of wet gaseous flow enriched with CO₂, out of method of oxygen burning comprises: compression of wet gas flow enriched with CO₂ to work pressure of the drying method, cooling of the wet gas flow enriched with CO₂ in at least one cooler; alternatively drying of the wet gas flow enriched with CO₂ in at least one dryer that contains at least one desiccant bed, and regeneration of the desiccant bed by means of heated regeneration gas passage thorough the dryer in direction opposite to flow of the wet gas enriched with CO₂, separation of the dried gas flow enriched with CO₂ in the cleaning method to gas flow of cleaned CO₂ and spent gas flow enriched with nitrogen and oxygen, at that spent gas flow enriched with nitrogen and oxygen is used as regeneration gas, and after regeneration the dryer is blown down at least once using HP gas flow enriched with CO₂ supplied from the compressor, at that the dryer is loaded to the work pressure of the method of drying by HP gas flow enriched with CO₂ and supplied from the compressor prior to each drying method.

EFFECT: invention reduces CO₂ losses and power consumption.
