Production of an aromatic dicarboxylic acid |
| abstract |
I) separating the effluent gas from the oxidation stage into an organic solvent-rich liquid stream and a water-rich vapor stream in a distillation stage; And ii) separating the aqueous purification mother liquor comprising an organic compound from the purified aromatic dicarboxylic acid crystals in a separation stage, comprising the steps of: , Iii) transporting the aqueous purification mother liquor from the separation stage to an extraction stage; iv) contacting the aqueous purification mother liquor with an organic liquid at an extraction stage to form an aqueous phase and an organic phase with the organic liquid at a temperature of at least 90 ° C to extract the organic compound from the aqueous purification mother liquor, Lower than the concentration of the organic compound in the aqueous purification mother liquor; And v) transporting the aqueous phase to the distillation stage. The present invention further provides an apparatus for carrying out the method. |
