Methods Dehydration experiments were carried out on the heavy oil by thermochemical sedimentation, dehydration with diluent and electric dehydration. Aim To solve the problem of dehydration of super heavy oil and to propose the best process parameters for dehydration of super heavy oil so as to meet the production needs. The results showed that the optimum parameters of thermo-chemical precipitation dehydration of ultra-heavy oil were as follows: the demulsifiers were RS 2 and LH 3, the dosage was 30 0 ~ 500 mg / L, the dehydration temperature was 90 ~ 95 ℃ and the sedimentation time was more than 96 h. Conclusions The thermochemical precipitation dehydration method can solve the problem of dehydration of super heavy oil. Under the above process conditions, the water content of the purified oil can reach below 3% after dehydration, and the oil content of the sewage reaches below 200 mg / L, meeting the production requirements
