摘　　要：针对微库仑法测定原油有机氯含量时无机氯对测定产生的严重影响,出现基线不稳、重复性不好等问题,通过开展无机氯产生的主要原因分析、馏分油中无机氯含量、改变馏分油非均质形态等实验,对相关影响因素净化处理后,馏分油中无机氯含量明显减小,基线不稳和重复性不好的问题得到明显改善,检测数据的精准度得以提升。In view of the serious impact of inorganic chlorine on the determination of organic chlorine content in crude oil by micro-coulometric method,such problems as unstable baseline and poor repeatability,experiments on the main causes of inorganic chlorine generation,inorganic chlorine content in distilate,and changing heterogeneous form of distilate,were carried out.After the purifica tion of related influencing factors,the content of inorganic chlorine in distillates is significantly reduced,the problems of baseline in-stability and poor repeatability are significantly improved,and the accuracy of detection data is promoted.
