摘要
针对大庆与冀东的混合原油,在实验室评价了MPTA型原油脱金属剂的脱金属性能,并在中国石化北京燕山分公司3Mt/a电脱盐装置上进行了工业化试验。实验室的间歇脱金属实验结果表明,在加剂量为80μg/g的条件下,MPTA型原油脱金属剂的性能优良。混合原油脱金属工业化试验结果表明,当MPTA型原油脱金属剂加量为60μg/g时,脱钙率可达82.20%,脱钠率为98.96%,脱镁率为91.90%,脱铁率为58.65%,脱镍率为24.23%;在脱除混合原油中主要金属元素时,混合原油的酸值变化不大,且均可控制在0.5mgKOH/g以下。
The effect of MPTA agent on the demetallization of Daqing and Jidong mixed crude oil was evaluated in laboratory, and the commercial trial was carried out in the electric desalting device of the No.2 atmospheric-vacuum distillation unit at Beijing Yanshan Company, SINOPEC. The results of batch scale lab test showed that good demetallization performance could be obtained at a MPTA added dosage of 80 μg/g. The commercial test results showed that at a MPTA added dosage of 60μg/g, the removal rates of calcium, sodium, magnesium, iron and nickel were 82.20%, 98.96%, 91.90%, 58.65% and 24.23%, respectively. Meanwhile, the acid value of treated mixed crude oil could be less than 0.5 mgKOH/g without significant change.
