Lang, R; Karwat, H

The NH/sub 3/ content is regulated in methanol used in a process for scrubbing out sour gases from gaseous mixtures and/or for preventing ice formation prior to the scrubbing step. The methanol is freed, after the scrubbing step, respectively of absorbed gaseous components and/or water, and reused in the cycle as scrubbing liquid and/or for preventing ice formation. A strong acid is added to the methanol from water-soluble ammonium salts. Thereby, dissolved salts are formed which are removed together with water. Deleterious trace acids are also removed by an analogous treatment with a basic compound. The acid/base treatments are conducted in succession.
