Abstract | Aqueous compositions comprising a mixture of a tertiary alkanolamine and a primary alkanolamine of the formula (I): R-CH(NH2)-CH2-OH, or mixtures thereof wherein R is H, or an alkyl group having from 1 to 8 carbon atoms are effective in the removal of acidic gases from a fluid stream containing same and show superior degradation properties as well as unexpectedly low degradation, corrosivity and metals solubility properties.
Ces compositions aqueuses renfermant un mélange d'une alcanolamine tertiaire et d'une alcanolamine primaire représentée par la formule (I): R-CH(NH2)-CH2-OH, formule dans laquelle R représente un hydrogène ou un groupe alkyle portant de 1 à 8 atomes de carbone, se révèlent efficaces, s'agissant d'extraire des gaz acides d'un courant de fluide. Ces compositions, qui se dégradent très bien, sont peu agressives, peu corrosives et n'ont qu'un faible pouvoir de dissolution des métaux. |
