Abstract: Based on produced liquid dehydration technology research in recent years, and targeted at the situation of difficult dehydration of oilfield EOR polymer flooding produced liquid, the efficient thermoelectric composite oil-water treatment process was put forward, and the high-efficiency thermoelectric composite oilwater separator was developed. This paper described the structure, principle and application of the device. Three means were used to achieve efficient oil-water separation such as high gravity field separation, thermochemical settlement and electric dehydration technology. As a result, water in processed oil was reduced to less than 5%, and the energy-saving effect was significantly increased as compared with similar-sized device, with the system energy losses being reduced by 15%. The device is highly integrated and low running costs.
