Verfahren zur Entfernung von CO2 und/oder H2S aus Olefine und Acetylene enthaltenden Gasen

摘要

A process for the removal of CO2 and/or H2S from gases containing olefins and acetylenes by absorption in an aqueous solution of an alkali metal salt of amino acid and desorption by decompressing and heating the solvent, which comprises treating the solvent, before or after desorption, with a hydrocarbon mixture substantially consisting of benzene for the purpose of removing impurities and, after said treatment, separating the hydrocarbon mixture from the aqueous solution.
