Standard Test Method for Total Mercury in Crude Oil Using Combustion-Gold Amalgamation and Cold Vapor Atomic Absorption MethodTranslate name
STANDARD published on 1.6.2020
Designation standards: ASTM D7623-20
Publication date standards: 1.6.2020
The number of pages: 6
Approximate weight : 18 g (0.04 lbs)
Country: American technical standard
Category: Technical standards ASTM
ICS Number Code 75.040 (Crude petroleum)
|Significance and Use|
5.1 The emission of mercury during crude oil refining is an environmental concern. The emission of mercury may also contaminate refined products and form amalgams with metals, such as aluminum.
5.2 When representative test portions are analyzed according to this procedure, the total mercury is representative of concentrations in the sample.
1.1 This test method covers the procedures to determine the total mercury content in a sample of crude oil.
1.2 The test method may be applied to crude oil samples containing between 5 ng/mL to 400 ng/mL of mercury. The results may be converted to mass basis, and reported as ng/g of mercury.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This work has been published in “Determination of Mercury in Crude Oil by Atomic Spectroscopy.”1.5 1.6 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
