The is an essential document for any quality control laboratory handling petroleum products. Whether you are testing crude oil, fuel oil, or asphalt, this distillation method offers a reliable, visual, and direct way to measure water contamination.
Minimize structural pipeline corrosion and prevent costly refinery system blockages or emulsification. 2. The Core Technical Principle
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. Astm D95 Pdf
Performing ASTM D95 accurately requires specialized glassware and a heat source. Key components of the Dean-Stark apparatus used include:
The core principle behind ASTM D95 is the azeotropic distillation of the test sample with a water-immiscible solvent. The apparatus used is the . The is an essential document for any quality
Water contamination can cause serious operational issues, such as: Corrosion:

The co-distilled solvent and water vapors rise into a condenser. Once liquefied, they drop into a graduated trap. Because water is denser than the solvent and insoluble in it, the water separates completely and settles at the bottom of the trap, allowing for direct volumetric measurement. 🛠️ Required Apparatus and Reagents
While versatile, the standard notes that volatile water-soluble materials may be measured as water, potentially affecting the final result.
