The invention relates to a method for regenerating an amine-containing wash solution which is obtained during gas purification and in which CO2 and sulfur compounds are chemically bonded as well as a system that is suitable for carrying out said method. According to the invention, a) the contaminated wash solution is heated, compressed, and expanded in several stages such that CO2 and sulfur compounds are separated, and b) the expanded wash solution is subdivided into two partial streams, and one partial stream is recirculated into the process.
L'invention concerne un procédé de régénération d'une solution de lavage renfermant des amines, obtenue lors de l'épuration de gaz, solution dans laquelle du CO2 et des composés du soufre sont liés chimiquement, ainsi qu'une installation pour la mise en oeuvre de ce procédé, lequel est caractérisé en ce que a) la solution de lavage contaminée est, en plusieurs étapes, respectivement, chauffée, comprimée et détendue, de sorte que le CO2 et les composés du soufre sont séparés, b) la solution de lavage détendue est divisée en deux courants partiels, et un courant partiel est recyclé dans le procédé.
