原油中硫含量测定技术的应用研究

Research on the Application of Sulfur Content Measurement Technology in Crude Oil

针对目前利用能量色散X射线荧光光谱法测定原油中硫含量所存在的效率低、经济性差的不足,提出了一种新的原油中硫含量测定方法。以紫外荧光法为核心,通过对不同稀释剂和不同混合比例条件下的最佳测定参数进行了分析。结果表明,当超声波作用时间为14min,测试温度为35°的条件下具有最佳的测试精度,为推动原油中含硫量测试方法的拓展奠定了基础。

A new method for determining sulfur content in crude oil is proposed to address the shortcomings of low efficiency and poor economy in using energy dispersive X-ray fluorescence spectroscopy to determine sulfur content in crude oil.Using UV fluorescence as the core,the optimal measurement parameters were analyzed under different diluents and mixing ratios.The results indicate that the optimal testing accuracy is achieved under the condition of ultrasonic action time of 14 minutes and testing temperature of 35℃,laying the foundation for promoting the expansion of sulfur content testing methods in crude oil.
