Abstract

Procedimiento de desacidificacion de una mezcla gaseosa que contiene constituyentes ácidos, en particular H2 S y/o Co2, según el cual se pone en contacto la mezcla gaseosa con una solución acuosa de amina, absorbiendo la solución de amina la mayor parte de los constituyentes ácidos de la mezcla gaseosa y se trate la solución de amina cargada en constituyentes ácidos por medio de un aporte de calor, a una temperatura y a una presión tales que la solución según el tipo de amina elegida pueda herbir a la temperatura elegida, caracterizado porque la amina e un alquilamino-2-etanol de fórmulas: R-NH-CH2-CH2_oh donde R representa un radical alquil de C1 a C6 inclusive, porque los caudales de gas ácido y de la solución de amina son regulados de tal modo que el número de moles de gas ácido absorbidos por mol de amina, o grado de carga, esté comprendido entre 0,7 y 1,2, teniendo la solución de amina una concentración en amina total de 0,5 a 6 moles por litro y preferentemente de 2 a 4 moles por litro, efectuandose la puesta en contacto de la solución de amina con la mezcla gaseosa a una temperatura comprendidas entre 40 y 100ºC.
