ABSORBENT FOR REMOVING CARBON DIOXIDE PROMOTED BY ADDITIVE IN HIGH PRESSURE

摘要

PURPOSE: A carbon dioxide absorbing agent is provided to improve the absorbing speed of carbon dioxide by applying a chemical absorbing process, which was used at a low pressure, at a high pressure. CONSTITUTION: A carbon dioxide absorbing agent is composed of methyldiethanolamine, cyclic amine, and water. A performance improving promoter is 7.5 weight% of the cyclic amine. 30 weight% of methyldiethanolamine is contained in the carbon dioxide absorbing agent. The cyclic amine is selected from a group including 2-methylpiperazine, trans piperazine, 2,5-dimethyl piperazine, 2-methyl piperazine, N-ethylpiperazine, pipecolinic acid, isonipecotic acid, methyl isonipecotate, N-alkyl-3-pipecoline, and the mixture of the same.
