原油脉冲电脱盐技术研究

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%。

STUDY ON THE PULSE ELECTRIC DESALTING TECHNIQUE OF CRUDE OIL

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...
