摘　　要：简介了负压间歇精馏的优势和本单位负压间歇精馏装置概况。通过试生产过程,完成了对真空泵、取样口、采出冷凝器的改造,解决了测温系统监测不准、釜残排放和液位计管线堵塞的问题,实现了本装置的正常生产的目的,为下步精馏试验做好准备工作。This article introduces the advantages of vacuum batch distillation and the general situation of the unit. Through the trial production process, the transformation of vacuum pump, sampling port, and recovery condenser was completed, and the problems of inaccurate monitoring of the temperature measurement system, the discharge of kettle residues, and the plugging of the liquid level gauge pipeline were solved, and the purpose of normal production of the device was achieved. To prepare for the next distillation test.
