Abstract

Un procédé de régénération d'un absorbant comprenant une solution aqueuse d'une N-(2-hydroxyalcoyl)amine primaire et/ou secondaire et contaminé par une orazolidone. L'absorbant, ou une fraction contenant l'oxazolidone obtenue à partir de lui, est chauffé à une température d'au moins 20 degrés C sous pression élevée en présence d'eau. Application à l'élimination de CO2 et/ou de COS d'un mélange de gaz.A process for regenerating an absorbent comprising an aqueous solution of a primary and / or secondary N- (2-hydroxyalkyl) amine and contaminated with an orazolidone. The absorbent, or a fraction containing the oxazolidone obtained from it, is heated to a temperature of at least 20 degrees C under high pressure in the presence of water. Application to the removal of CO2 and / or COS from a mixture of gases.
