用燃烧炉及离子色谱仪测定原油中总氯、有机氯、无机氯含量的方法研究

Determination of Total Chlorine, Organic Chloride and Inorganic Chloride Content in Crude Oil by Furnace and Ion Chromatograph

摘要: 使用燃烧炉及离子色谱仪测定原油中总氯含量，然后用常压蒸馏方法（ASTM D86）进行原油切割，得到204 ℃前馏分油，以燃烧炉及离子色谱仪测定其中有机氯含量，换算得到原油中有机氯含量，最后通过差减法计算得到原油中无机氯含量.

Abstract: A method for the determination of total chlorine in crude oil using a furnace and an ion chromatograph has been established. An atmospheric distillation method was used to obtain the fraction before 204 ℃(ASTM D86). The total chlorine content in the fraction was also determined by the furnace and ion chromatography.According to the result and the percentage of fraction in crude oil the organic chloride content can be calculated, and the inorganic chloride content in crude oil can be obtained by subtraction.
