Title:
METHOD OF ABSORBING AND REMOVING CARBON DIOXIDE AND*OR HYDROGEN SULFIDE BY SOLUTION
Document Type and Number:
Japanese Patent JPS55102421
Kind Code:
A
Abstract:
The removal of CO2 and mixtures thereof with H2S from gaseous mixture containing same, is carried out by using an absorbing solution which comprises a first activating substance chosen from aminoacids and primary and secondary ethanolamines, which effects the initial absorption of CO2 with formation of a carbamate, a second activating substance chosen from As2O3 and its derivatives, secondary ethanolamines and ammonia, which promotes the hydrolysis and decomposition of the carbamate as the latter forms, and a third substance of a basic nature, which effects the quantitative absorption of CO2 or CO2+H2S.
