Abstract: Disclosed is a method for deacidifying a fluid stream containing acidic gases as contaminants, according to which the fluid stream is brought into intimate contact with a washing liquid in at least one absorption step. Said washing liquid represents an aqueous solution containing a) tertiary aliphatic alkanolamines (alkanolamine A), at least 30 percent by weight of said tertiary aliphatic alkanolamines being 3-dimethylamino-1-propanol, and b) secondary aliphatic amines (activator B), at least 20 percent by weight of said secondary aliphatic amines being piperazin. The fluid stream which has been essentially purified of the acidic gases is then separated from the washing liquid that is loaded with acidic gases.

Abstract: Procedimiento para desacidificar una corriente fluida que contiene gases ácidos como impurificaciones, en donde en por lo menos una etapa de absorción se pone la corriente fluida en contacto íntimo con un líquido de lavado, cuyo líquido de lavado es una solución acuosa, que contiene a) alcanolaminas alifáticas terciarias (alcanolamina A), tratándose en caso de por lo menos el 30% en peso de las alcanolaminas alifáticas terciarias de 3-dimetilamino-1-propanol y b) aminas alifáticas secundarias (activador B), tratándose en caso de por lo menos el 20% en peso de las aminas alifáticas secundarias de piperacina, y se separan la corriente fluida substancialmente purificada del líquido de lavado cargado con los gases ácidos.
