摘　　要：针对中国石化齐鲁股份公司氯碱厂5万t/a离子膜烧碱装置运行中出现的阳极气液分离器内压力升高的现象,分别进行了100%、80%和120%3个不同负荷下,气相出料管线、液相出料管线和阳极气液分离器的物料衡算,结论是气液分离器规格小,分离空间不足。通过增大气相出料管径,改大气液分离器,使得气液分离器压力由正压变为负压,且气液分离效果好。According to the problem of pressure increase in anode gas-liquid separator happened during the running of 50 kt/a ion-exchange membrane caustic soda facility in Chlor-Alkali Plant of Qilu Petrochemical Inc.,the mass balance in gas outlet pipe,liquid outlet pipe and anode gas-liquid separator at three kinds of load,that was 100%,80% and 120%,were carried out.The results showed that the gas-liquid separator was smaller and the separation space was not enough.After widening the diameter of gas outlet pipe,enlarging the gas-liquid separator,the pressure in the gas-liquid separator changed from positive into negative pressure,and good result of gas-liquid separation was obtained.
