摘要: 分析原油脉冲电脱盐技术的脱盐/脱水机理。以10 L/h的两级动态原油脉冲电脱盐装置,采用正交试验法对影响原油脉冲电脱盐效果的7个因素进行研究。结果表明:在原油处理量提高60%的情况下,采用优选的工艺条件,二级电脱盐后原油的盐质量含量小于3.0 mg/L,水质量含量小于0.3%,切水含油量小于100 mg/L,达到了深度脱盐的技术要求;与普通交流电脱盐相比,脉冲电脱盐节电率可达58.9%。

Abstract: The mechanism of pulse electric desalting/dehydration for crude oil was discussed. Seven factors related to the operation efficiency of pulse electric desalting technique were studied by orthogonal test design method,using a 10 L/h continuous two-stage desalting unit. The results showed that when the crude processing capacity increased by 60%, the contents of salt and water in the secondary desalted crude oil were less than 3.0 mg/L and 0.3%, respectively, furthermore, the oil content in waste water was less than 100 mg/L, which well met the requirements of deep desalting. The electricity-saving rate of pulse electric desalting technique could reach 58.9% as compared with conventional AC electric desalting technique under optimum operating conditions.
