Measure a specific volume or weight of the sample (typically 100 mL or 100 g) into the distillation flask. Step 3: Adding the Solvent

In the petroleum industry, even a small amount of water in oil can lead to catastrophic equipment failure, reduced efficiency, and costly downtime. To prevent this, laboratories and refineries worldwide rely on a specific testing standard: .

Drop in a few boiling chips or anti-bumping granules to ensure smooth, safe boiling. Step 2: System Assembly Connect the distillation flask to the graduated trap. Fit the reflux condenser to the top of the trap.

Tars and other viscous semi-solid petroleum compounds. Measure a specific volume or weight of the

[ \textWater (vol %) = \frac\textVolume of water (mL)\textMass of sample (g) \times 100 ]

This test method is applied to a broad range of materials, including: Crude oils, fuel oils, and residual fuel oils. Lubricants and lubricating oils. Distillate fuels. Bituminous materials, tars, and asphalts. Why is Water Determination Crucial? Step 2: System Assembly Connect the distillation flask

Typically a short-neck, round-bottom flask (500 mL or 1000 mL) or a metal still.

International trade contracts strictly limit allowable water percentages to prevent paying for water volume instead of product. 3. Apparatus and Reagents

The volume of the separated water is read directly from the graduated scale on the trap. Required Testing Apparatus

is the globally recognized Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation. It is a critical procedure used in the oil and gas industry to accurately measure water content, which directly impacts the quality, safety, and price of petroleum products during refining and trade. Core Method Overview The process uses a Dean-Stark distillation technique.
