Crude oil dewatering is a basic process requirement in the process of oil exploitation, transportation and refining. The classical dewatering method consists of natural sedimentation, heating separation, etc. Due to the increase of the difference of oil storage in various oil fields, the original dewatering process can no longer meet the requirements, especially for heavy oil, the heating method can not effectively separate oil and water for 24 hours.

The APT series multifunctional crude oil dehydration tester developed by our factory adopts the treatment method of "electrochemical method is the main method, thermochemical method is the auxiliary method", which effectively solves the problem of dehydration and desalting of heavy oil. The test shows that APT series automatic crude oil dehydration tester can separate oil and water in only 1 hour for general heavy oil.

The instrument has the program segment temperature control, three segments of high pressure electric field, electric field size can be set, each test time can be set, according to the program set automatic heating, stirring, electric field, water, distillation, cooling, oil recovery and automatic cleaning functions. In addition, in order to ensure the safety and reliability of the test, the instrument also has high voltage overcurrent protection, over temperature and over pressure (pressure) power protection, sound and light alarm and other functions. It is an ideal test device necessary for each research department to study crude oil dehydration and desalting.
