| titleOfInvention | Process for recovering water, metals and organics from the production of polycarboxylic acids |
| abstract | A process for recovering water, metals, soluble organic matter and insoluble organic matter in a mother liquor stream from the separation stage of the polycarboxylic acid production process, cooling the stream to a temperature at which the dissolved organic matter precipitates; Separating the precipitated organic matter from the liquid stream, recycling the organic matter to the polycarboxylic acid production process, and then treating the liquid stream from step (b) with alkali to convert the residual organic matter to an alkali salt form; Converting the existing metal to an insoluble form, recovering the insoluble metal from the liquid stream, and passing the liquid stream from step (d) comprising an alkali salt of organic matter through a membrane separation unit, In the membrane separation unit, the liquid flow is separated into a permeate containing water and a concentrate containing water and an alkali organic salt; Comprising the steps of recycling the liquid to the manufacturing process of a polycarboxylic acid, and recovering the concentrate process. |
