| titleOfInvention | A D-acid purification membrane integrated system |
| abstract | The utility model discloses a D-acid purification membrane integrated system, which comprises a first-level clarification system, a second-level preliminary concentration system, a third-level high-fold concentration system and a fourth-level deglycine system. The first-level clarification system and the second-level preliminary concentration system The system, the third-stage high-expansion concentration system and the fourth-stage deglycine system all include a liquid storage tank, a feed pump, a filter and a membrane module, and the second-stage preliminary concentration system, the third-stage high-expansion concentration system and the fourth-stage deglycine system also include High-pressure pump. In the present invention, after the original solution mainly composed of D-acid and glycine is processed by the membrane integrated system of ultrafiltration, nanofiltration and reverse osmosis, the D-acid and glycine are effectively separated, and the obtained concentrated solution of D-acid is in the D-acid content is greater than 100g/L, glycine concentration is lower than 20g/L, crystallize after adding hydrochloric acid, obtain D-hydrochloride after filtration, D-hydrochloride can be directly sold or esterified to obtain D-ethyl ester For sale, the product yield can reach more than 85%. |
