原油有机氯分析方法
|
摘要
为准确分析原油有机氯含量,采用两种分析方法比对,方法一是利用SY/T0536-2008所得试样上层油液,通过库仑法分析有机氯含量;方法二利用原油总氯与无机氯之差分析有机氯含量,最终得出因为低沸点氯代烃的挥发造成方法一所测得有机氯含量偏低;方法二比方法一分析得到的有机氯更为准确,同时相对于现有国家标准所执行的有机氯含量测定方法标准误差会更小。
In order to analyze the organic chlorine content of crude oil accurately, two kinds of analysis methods were used. MethodⅠ: the organic chlorine content was analyzed by Coulometric method with the upper oil liquid of the SY/T0536 sample. MethodⅡ: the organic chlorine content was analyzed by the difference between the total chlorine and inorganic chlorine of crude oil. The results showed that, the volatilization of low-boiling chlorinated hydrocarbons caused low organic chlorine content measured value of methodⅠ, the method Ⅱ was more accurate than the methodⅠ. At the same time, the standard error of the method Ⅱ was smaller than that of the existing organic chlorine content determination method.
