The Use of Dry Screw Vacuum Pump in API manufacture process

Li Aizhen;Shuai Xinfa;Liao Xuesong;Shenzhen Salubris Pharmaceuticals Co., Ltd.;Shenzhen Environmental Protection Co., Ltd.;  
Dry screw vacuum pump is adopted instead of water-ring vacuum pump during suction filtration and drying under reduced pressure in API manufacture process, and a condenser was installed after the dry screw vacuum pump, which was used to recover the volatile organic solvents. The method could reduce the cost and decrease the release amount of waste air/water.
