FIELD: process engineering.
SUBSTANCE: proposed method comprises bringing gas in contact with pitch, wetting said pitch with water, trapping steam and carbon dioxide from pitch, and separating carbon dioxide from steam. Pitch may be placed in chamber or multiple interconnected chambers. First said chamber contains pitch that, first, gets in contact with gas, every next chamber contains wetted pitch and carbon dioxide collected in longer period compared with that for previous chamber and so on up to the last chamber. Secondary sorbents may be used for additional separation of carbon dioxide from steam.
EFFECT: removal of byproducts incoming from ambient medium.
