摘要
在原料药生产的抽滤及减压干燥工艺中应用干式螺杆真空泵替代水环式真空泵,并在干式螺杆真空泵后加装冷凝器冷凝回收挥发性有机溶剂,达到降低成本、减少废气废水的效果。
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.
