A Study on Adaptability of Analytical Methods for Sulfur Content in Petroleum Products

This paper introduces three kinds of analytical methods for sulfur content in petroleum products including mi-crocoulometric method, lamp method and energy chromatic dispersion x - ray fluorescence spectrum method. The features and application scope of these methods are compared. It is believed that when sulfur content is below 100f33g/g, microcoulometric method has lower error, when sulfur content ranges from 100 to 1000f33g/g, all these methods are applicable, when sulfur content is above 1000 f33g/g, fluorescence spectrum method is more accurate.
