METHOD OF REGENERATING FLUID ABSORBING ACID GAS CONTAINING METHYL DIETHANOLAMINE AND DERIVATIVE OF PIPERAZINE OF LOWER ALKYLS |
摘要 |
method of regeneration of fluids absorbing acid gases. SUBSTANCE: method of regeneration of fluid absorbing acid gas is distinguished by the fact that gas mixture containing acid gas comes in contact with absorbing fluid containing methyl diethanolamine and derivative of piperazine having one or two lower alkyl groups with C1-C4 in capacity of substituent in heterocyclic ring for absorption of acid gas by absorbing fluid, and subsequent regeneration of absorbing fluid in regeneration tower having temperature not below 40 C by freeing of acid gas from it. Method allows efficient regeneration of fluid absorbing acid gas containing methyl diethanolamine and derivative of piperazine of lower alkyls even at relatively low temperature of 40 C, and it is possible to regenerate more efficiently at temperature of 60 C and higher. EFFECT: higher efficiency. 4 cl, 9 dwg, 1 tbl |
