| titleOfInvention | A kind of thickening method of camphorsulfonic acid solution in L-Phenylglycine production process |
| abstract | The invention discloses a kind of thickening method of camphorsulfonic acid solution in L-Phenylglycine production process.By in phenylglycine production process using camphorsulfonic acid make resolving agent generation solution be centrifuged and wash after produce mother liquor process：（1）Decrease temperature crystalline pre-processes；（2）Level-one high pressure reverse osmosis membrane thickening；（3）Two level high pressure reverse osmosis membrane thickening；（4）L-Phenylglycine Crystallization Separation；（5）Three-level high pressure reverse osmosis membrane thickening.Its concentration is concentrated to 30%~32% from 8%~9%, can be returned directly to recycle in former resolution process, production Water circulation is into original production process.The present invention makes camphorsulfonic acid solution enrichment to more than 30%, and compared with existing multiple-effect evaporation, without phase-change, energy consumption can reduce by more than 60%, phenylglycine, camphorsulfonic acid, production water can reuse, realize recycling, energy saving and clean manufacturing. |
