Abstract

Un proceso para la recuperacion de dioxido de carbono, que comprende: (a) un paso de absorcion que consiste en poner una corriente gaseosa de alimentacion que contiene dioxido de carbono en contacto gas-líquido con un fluido absorbente, con lo cual al menos una porcion del dioxido de carbono presente en la corriente gaseosa es absorbida en el fluido absorbente para producir (i) una corriente gaseosa refinada que tiene un contenido reducido de dioxido de carbono y (ii) un fluido absorbente rico en dioxido de carbono; (b) un paso de regeneracion que consiste en tratar el fluido absorbente rico en dioxido de carbono a una presion mayor que 3 bar (presion absoluta) a fin de liberar dioxido de carbono y regenerar un fluido absorbente pobre en dioxido de carbono que se recicla para uso en el paso de absorcion, en donde el fluido absorbente es una solucion acuosa de amina que contiene una alcanol-amina alifática terciaria y una cantidad eficaz de un promotor de la absorcion de dioxido de carbono, mostrando la alcanol-amina alifática terciaria poca descomposicion en condiciones especificadas de temperatura y presion en co-existencia con dioxido de carbono. La alcanol-amina alifática terciaria no contiene en su estructura molecular un átomo de N que está sustituido con más de un resto 2-hidroxietilo, o un átomo de N que está sustituido a la vez con un resto 2-hidroxietilo y un resto metilo. Las alcanol-aminas alifáticas terciarias preferidas se seleccionan del grupo constituido por N-etildietanolamina, 2-(dimetilamino)etanol, 2-(dietilamino)-etanol, 3-(di-metilamino)-1-propanol, 3-(dietilamino)-1-propanol, 1-(dimetilamino)-2-propanol, y 2-(diisopropilamino)-etanol.
