摘要
FIELD: chemistry.;SUBSTANCE: method comprises the following steps: 1) using composite water absorber, consisting of organic amine and functionalized ionic liquid, as an absorbent CO2; 2) forming different layers of the liquid by means of settling to transparency; 3) heating and decomposition of the liquid produced by means of separation and rich in A·CO2 and B·CO2, for recycling, to obtain highly concentrated gas CO2 and composite water absorbent; 4) recycling composite water absorbent obtained at step 3); 5) cooling the highly concentrated gas CO2 for condensation of hot water vapor in it; 6) gas-liquid separation of highly concentrated gas CO2, after cooling at step 5), to produce gas CO2 with purity ≥ 99 %; 7) conversion of high-purity gas CO2 in liquid to obtain a product of highly concentrated liquid carbon dioxide industrial type.;EFFECT: method provides higher efficiency of trapping, lower power consumption and simple implementation.;14 cl, 1 dwg
