ASTM WK33782

    New Practice for Standard Practice for Determination of Total Volatile Sulfur in Gaseous Hydrocarbons, Liquefied Petroleum Gases and Natural Gas by Oxidative Combustion, Purge and Trap and Ultraviolet Fluorescence Detection

    (What is a Work Item?)

    WK33782

    1. Scope

    0.010-10 mg/kg Total Sulfur

    The sulfur content of gaseous hydrocarbons, LPG, and LNG used for fuel purposes contributes to total SOx emissions and can lead to corrosion in engine and exhaust systems. Some process catalysts used in petroleum and chemical refining can be poisoned by trace amounts of sulfur-bearing materials in the feed stocks. This test method can be used to determine the total volatile sulfur content in process feeds, to control the total volatile sulfur content in finished products and, as applicable, to meet regulatory requirements. D03 has identified the need to lower the detection limits of Total Sulfur by combustion UVF below 1 mg/kg
