Standard Test Method for Total Water in Liquid Butane by Liquefied Gas Sampler and Coulometric Karl Fischer Titration

Importancia y uso:

5.1 High water concentrations can have a detrimental effect on the many uses of liquefied petroleum gas (LPG). Wet butane, propane, and other low molecular weight hydrocarbon products can cause operational issues in customer equipment and downstream processes. Water can cause corrosion problems and create safety hazards during the storage, distribution and use of liquefied petroleum gas (LPG) and pressurized low molecular weight hydrocarbon samples.

5.2 While the dryness of propane may be monitored with a “functional” test such as the valve freeze Test Method D2713, this test method provides an analytical method to directly measure water content in LPG and pressurized low molecular weight hydrocarbons and their mixtures.
