| titleOfInvention | Method for purifying an extraction liquid |
| abstract | This invention relates to a method for the purification of a depleted organic extraction liquid from a production process, said method comprising the following steps in the given sequence: a. intensive mixing the depleted organic extraction liquid with an amine-containing liquid in a first liquid-liquid extraction step, b. phase separation of the two liquids of step a., c. washing of the organic extraction liquid phase of step b. with an aqueous liquid in a second liquid-liquid extraction step, d. phase separation of the two liquids of step c., and e. recycling of the purified organic extraction liquid into the production process, wherein the enriched amine-containing phase of step b. and the enriched aqueous phase of step d. are purified and recycled into steps a. resp. step c.. |
