摘　　要：从克拉玛依石化公司2．00Mt／aⅡ套常减压蒸馏装置电脱盐前引出1．5m3／h的试验原油，采用自行研发的络合脱钙剂，在自建的小型工业电脱盐试验装置进行连续脱钙试验。结果表明：对于含钙量较低的原油，在注水率为6％、脱钙剂加剂量为60μgk时，通过结构通道混合器与管填料混合器的两级油剂混合作用，金属钙、镁、铁的脱除率分别为71．5％～78．2％，32．3％～45．5％，30．0％～38．2％，脱钙油含水量小于0．3%，脱钙后排水的各项指标达到工业水车间进水要求。The 1.5 m3/h crude from 2.00 Mt/a No. 2 atmospheric and vacuum distillation unit in Karamay Petrochemical Co. was fed into in a self-made small scale electric desalting device for decalcifi- cation test with own developed complexing decalcifying agent. The results show that for low calcium content crude oil, 6% water injection and dosage of decalcifying agent 60 μg/g, using a structured chan- nel mixer followed by tube packing mixer, can get the removal rate of Ca, Fe and Mg of 71.5%- 78.2 %,32.3 %-45.5 % and 30.0%- 38.2%, respectively. The water content in decalcified oil is less than 0.3%. The discharged water meets the quality requirements for industrial use.
