在矿场原油预处理装置的脱水和脱盐过程中,要从沉降罐排水,而且“油-水”两相要保持一定的分界面。可用各种测定器来控制界面(如浮球、电容和超声波等),如果沉降罐内存在的是清晰的相界面,那么这些仪器均可正常工作。若沉降罐内形成的是“繁杂的”乳状液,而且相界面处机械杂质和沥青的含量很高,那么要测定这种界面的状态就相当复杂了。 In the process of dewatering and desalination of the crude oil pretreatment plant in the mine, drainage is to be carried out from the settling tank, and the “oil-water” phase should maintain a certain interface. Various gauges can be used to control the interface (eg, float, capacitor, ultrasonic, etc.) and these instruments work well if there is a clear phase interface in the settler. If the settling tank is formed within the “complicated” emulsion, and the phase interface of mechanical impurities and bitumen content is very high, then the determination of the interface state is quite complicated.
