Abstract

Un método para la eliminación de sales de bases estables al calor, tales como sales de amina, se da a conocer. El método de la presente invención se puede utilizar para reducir el nivel de sales estables al calor en una corriente de gas solvente en un proceso de eliminación de gases ácidos. Un solvente en donde la carga de gas ácido pobre es alta es separado primero para lograr una carga de gas pobre aceptable. La solución pobre se recupera a continuación, utilizando uno o más métodos. La base purificada o solución de amina se pueden utilizar de nuevo para eliminar los gases ácidos a partir de una corriente de gas. Un proceso para la recuperación de gas ácido de una corriente de gas ácido también se da a conocer. El proceso comprende también una reducción del nivel de sales estables al calor en la corriente de gas solvente.
