Zusammenfassung:FIELD: cleaning gas mixtures from CO2 by multi-stage absorption method; chemical and oil-and-gas industries. ^ SUBSTANCE: proposed method includes absorption of CO2 from gas mixture by means of water in four absorbers (3,4,5 and 6) interconnected in succession. Water is fed to absorbers in parallel by means of one pump (7). Gas mixture to be cleaned contains 60-70 mass-% of CO2. Diameters of absorbers are decreased successively in such way that velocity of gas mixture in absorbers is within limits ensuring required final concentration of CO2 in cleaned mixture and height of absorbers is approximately equal. ^ EFFECT: high degree of cleaning gas mixture. ^ 1 dwg
