摘要
Abstract
Ultrasonic emulsion breaking technology is a novel crude oil emulsion breaking technology, with the advantages of low energy consumption, good effect and no pollution. Aiming at mixed crude oil in northern Shaanxi, the ultrasonic technology was applied to five sets of crude oil desalting installations in Yan'an, Yongping and Yulin oil refineries of Shaanxi Yanchang Petroleum Group Oil Refinery and Chemical Company. The results show that after using ultrasonic technology in crude oil electrostatic desalting, the process has no more need of demulsifier and it operates stably. The average salt content in crude oil after removal decreases from 3-5 mg/L to 3 mg/L below, and the average oil content in total drainage decreases from 242. 5 mg/L to 76. 6 mg/L. The application of the technology can reduce the generation amount of high water cut sump oil, and can significantly reduce the electric current in desalination tank of all levels. The economic benefit is remarkable and the technology has good application prospect.关键词
