ASTM D95 does not exist in isolation; several other ASTM standards are closely related. Understanding these standards can provide a more complete picture of the testing landscape.
The implications of ASTM D95 extend beyond the laboratory, influencing various sectors:
It is critical for quality control, determining compliance with specifications, and accurate commercial transactions.
The trap collects the condensed liquids and allows for measurement. Traps come in various capacities (e.g., 2 mL, 5 mL, 10 mL, or 25 mL) with distinct graduation marks to handle different expected water volumes accurately. Astm D95 Pdf
By delving into the specifics of ASTM D95 and its applications, industry stakeholders can better navigate the complexities of crude oil quality assessment and management, ultimately contributing to more efficient and sustainable practices in the oil and gas sector.
: The petroleum sample is mixed with the solvent and heated. Because water and the solvent form an azeotrope, they boil and vaporize together at a lower temperature than their individual boiling points. Condensation
ASTM D95, titled "Standard Test Method for Water and Sediment in Crude Oil by Centrifuge," is a widely adopted standard that outlines a procedure for determining the water and sediment content in crude oils. This test method is essential for assessing the quality of crude oil, influencing everything from processing and refining efficiencies to the overall cost and quality of petroleum products. ASTM D95 does not exist in isolation; several
Look for the current active version designation (e.g., ASTM D95-13R18, where the number after the hyphen indicates the year of original adoption or latest revision).
However, ASTM D95 remains the method of choice when:
Water, % (V/M)=(Volume of Water in Trap (mL)Mass of Sample (g))×100Water, % (V/M) equals open paren the fraction with numerator Volume of Water in Trap (mL) and denominator Mass of Sample (g) end-fraction close paren cross 100 Precision Limits The trap collects the condensed liquids and allows
Adjust the heat source so that the distillation rate profile yields roughly into the trap.
The solvent distills over, carrying the water from the sample along with it as a vapor mixture.
