摘要：The effect of paraffin in crude oil on the electric desalting and dewatering process was studied in this paper. The test result manifested that the dynamic viscosity of crude oil increased with the increase of paraffinic content in crude oil. Paraffin in crude oil exerts a great influence on the electric desalting and dewatering process because paraffin leads to higher viscosity of crude oil and emulsion stability as well as inefficient dewatering, and hence decreases the desalting efficiency. Some kinds of demulsifier series were tested in the process of the electric desalting and dewatering. The triblock copolymer structure of PO-EO-PO for polyhydric alcohol is more effective with high-paraffin crude oil than the diblock of PO-EO. Diamine series polymerized with propylene oxide (PO) were the most compatible with this type of crude oil for dewatering, whereas, polyamine series polymerized with propylene oxide (PO) and ethylene oxide (EO) were the most compatible for desalting.
