ASTM WK35244

    New Test Method for Determination of Water Content of Liquefied Petroleum Gases (LPG) Using Electronic Moisture Analyzers

    (What is a Work Item?)

    Developed by Subcommittee: D02.H0 | Committee D02 | Contact Staff Manager



    WK35244

    1. Scope

    This test method covers the quantitative determination of the dissolved water in liquefied petroleum gases (LPG) in the range of (to be determined) mg/kg using an electronic moisture analyzer. These analyzers use an aluminum oxide moisture sensor to measure absolute humidity, and are calibrated to report the water content of liquid phase hydrocarbons. References: ILS #516 Historical Work Item #12013

    There is currently no standard that measures moisture in liquid phase LPG. Dryness of propane is controlled with a "functional" test, D2713, the Valve Freeze Method. Wet propane and other LPG products cause operational and other issues in customer equipment and downstream processes. This method will be used for quality control, and potentially in specifications. Users include refineries/producers, pipeline operators, terminals, and chemical plants.
