| titleOfInvention | Method for the recovery of alkaline solution and method for producing regenerated cellulose moulded parts comprising such a method |
| abstract | A method (100, 101, 102) for recovering an alkaline solution (1) from a waste liquor (2) contaminated with hemicelluloses (5) and a method (200, 300) for treating (210, 310) a starting material containing cellulose are used (203, 303) having such a method (100, 101, 102) shown, in which the waste liquor (2) as a feed stream (6) via a separation process (7, 50) into at least one alkaline-enriched target fraction (8), and at least a residual fraction (9) containing hemicelluloses (5) is separated. In order to obtain a recovered alkaline solution with high purity, it is proposed that the separation process (7, 50) is a chromatographic separation process (7, 50) and the feed stream (6) therein as part of a mobile phase (10) through an alkali-resistant stationary one Phase (11) is performed in order to separate this into the target fraction (8) and the remaining fraction (9). |
