In the past, due to the adoption of traditional filter cloth filtration and pH adjustment in the extraction and purification processes, the eight peaks of L-serine production had problems such as large acid and alkali consumption, multiple wastewater discharges, and low product yield. In order to reduce energy consumption and alleviate environmental pressures, Hefeng Pharmaceutical Co., Ltd. cooperated with Hubei University of Technology. In March 2007, it successfully developed advanced membrane separation technology. Subsequently, the company also invested 3.6 million yuan in the membrane separation technology transformation of the serine production process, so that hydrochloric acid, protopine and other raw materials used to substantially reduce the amount of wastewater discharge is only 1/6 of the original, L-serine yield from the past The 80% increase to 98% can reduce the production cost of 4.2 million yuan per year for the eight peaks.
On February 25th, L-Serine membrane separation technology of Hubei Peak Pharmaceutical Co., Ltd. was identified by scientific and technological achievements organized by the Science and Technology Department of Hubei Province.
