摘要： 结合高频电脱盐技术在大榭石化的应用实例，阐述了高频电脱盐技术的原理，对高频电脱盐技术在高酸重质原油中的电脱盐效果及节能减排效果进行了评价。大榭石化通过对2.25 Mt/a沥青装置一级电脱盐罐实施高频电脱盐技术改造后，取得了较好的效果，平均电脱盐率提高了6.24%，电脱切水含油质量浓度和COD分别降低了73 mg/L和352 mg/L，电脱系统设备电耗相对改造前节省约20%，每吨原油破乳剂平均消耗量降低了4.13 g，每年直接经济效益在167万元以上。

Abstract: The theory of high frequency desalting technology was illustrated through the application case of high frequency desalting technology on CNOOC Daxie, and the desalting effect on high acid crude oil and it’s energy saving was evaluated. The result shows that by using high frequency electric desalting transformation on first order electric desalting tank of 2.25 Mt/a asphalt unit, the average electric desalting rate has been increased by 6.24%, the oil concent and COD in blow-down water has been decreased by 73 mg/L and 352 mg/L,respectively.Power consumption of electric desalting tank has been saved 20%, average demulsifier consumption of per ton of crude oil has been decreased by 4.13 g, the direct economic benefit was above 1.67 million yuan.
