Standard Test Method for

Sediment in Crude Oil by Membrane Filtration1

This standard is issued under the fixed designation D 4807; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

This standard has been approved for use by agencies of the Department of Defense.

e1 NOTE—Footnote 5 was updated editorially in August 2005.

1. Scope*

   1. This test method covers the determination of sediment in crude oils by membrane filtration. This test method has been validated for crude oils with sediments up to approximately

      0.15 mass %.

      1. The accepted unit of measure for this test method is mass %, but an equation to convert to volume % is provided (see Note 6).

      2. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

      3. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. For specific warning statements, see 6.1 and Annex A1.

3. Summary of Test Method

   1. A portion of a representative crude oil sample is dissolved in hot toluene and filtered under vacuum through a 0.45-µm porosity membrane filter. The filter with residue is washed, dried, and weighed to give the final result.

4. Significance and Use

   1. A knowledge of the sediment content of crude oil is important both in refinery operations and in crude oil com- merce.
