轻质燃料油硫含量分析方法评价

EVALUATION ON SULFUR CONTENT ANALYSIS METHODS FOR LIGHT FUEL OIL

对轻质燃料油硫含量分析所使用的紫外荧光法、单波长色散X射线荧光光谱法、电量法3种方法进行评价,就其影响因素及3种分析方法的一致性进行比对分析。结果表明,3种分析方法测定低硫含量样品分析结果基本一致,重复性好、准确度高。同时对不同分析方法的优缺点进行了比较,在硫含量分析方法的选择时,可根据馏分情况、硫含量及实验室设备情况等因素来选择准确、高效、经济的检测方法。

Three methods including the ultraviolet fluorescence method, the single wave- length dispersive X ray fluorescence spectrometry method and the electric quantity method used in analysis of the sulfur content in light fuel oil were evaluated. Effect factors and the consisten- cy of the above -mentioned three analytical methods were compared and analyzed. The results of the three analytical methods for determination of low sulfur content were basically consistent, possessed good repeatability and high accuracy. The advantages and disadvantages of different analysis methods were compared; the aeeurate, efficient and economic inspection method could be selected according to the fraction, sulfur content and laboratory equipment situation.
