ABSTRACT:
A method is provided for minimizing the organic waste found in an aqueous process stream of products and refined products from a liquid-liquid extraction process. The aqueous process stream contains small quantities of interfering substances in the form of an organic extraction agent and decomposition products of the extraction agent and is treated with an agent which selectively, practically quantitatively and reversibly sorbs the interfering substances. This agent is a macroporous sorption resin based on polystyrene cross-linked with divinyl benzene. The sorption resin, after being charged with the interfering substances, is regenerated by being brought into contact with a regenerating solvent. The regenerating solvent is then separated from the sorption resin and subjected to a distillation. The distillate consists of pure solvent and is put back into circulation to regenerate sorption resin. The extraction agent obtained as the distillation residue is recirculated, after dilution with a dissolving diluent, and returned into circulation in the extraction process.
