Press Release Summary:
Targeting the measurement of gaseous hydrocarbons and other components of gaseous streams, ASTM WK33788, Test Method for Determination of Hydrocarbons and Nonhydrocarbon Gases in Gaseous Mixtures by Gas Chromatography will help users comply with U.S. EPA's greenhouse gas regulation. Methodology described in proposed standard enables separation of low molecular weight hydrocarbons and inert gases for detailed analysis of the composition of gaseous streams.

Proposed ASTM Standard Facilitating Compliance with Greenhouse Gas Regulations
W. CONSHOHOCKEN, Pa., - The need for a consensus standard targeting the measurement of gaseous hydrocarbons and other components of gaseous streams allowing users to better comply with U.S. Environmental Protection Agency's greenhouse gas regulation provided the impetus for the development of a proposed new ASTM International standard meeting this need.
ASTM WK33788, Test Method for Determination of Hydrocarbons and Nonhydrocarbon Gases in Gaseous Mixtures by Gas Chromatography, is under development by Subcommittee D03.07 on Analysis of Chemical Composition of Gaseous Fuels, part of ASTM International Committee D03 on Gaseous Fuels.
According to Shannon Canfield, marketing chemist, Wasson-ECE Instrumentation, and chairman of D03.07, ASTM WK33788 is a merging and enhancement with updated technology of two ASTM standards, ASTM D1945, Test Method for Analysis of Natural Gas by Gas Chromatography, and ASTM D1946, Practice for Analysis of Reformed Gas by Gas Chromatography.
"ASTM D1945 and ASTM D1946 will remain on the books as the natural gas industry uses them just as they are written," says Canfield. However, Canfield notes that many users perform gaseous fuel hydrocarbon analyses using hardware and technology such as capillary columns and various detectors that are not included in D1945 and D1946.
"In order to comply with what is being used in the industry and to provide regulators with a more comprehensive method to point to, we decided to develop ASTM WK33788," says Canfield.
The proposed new standard will cover the analysis of parts per million to percent level inert gases such as hydrogen, oxygen, argon, nitrogen, carbon monoxide and carbon dioxide along with low ppm level hydrocarbons such as methane, ethane and propane in various gaseous streams. The proposed new standard is intended to be performance based. The methodology described in the proposed standard enables separation of low molecular weight hydrocarbons and inert gases for a detailed analysis of the composition of gaseous streams.
Refineries and chemical plants, along with contract laboratories and regulatory agencies, will be the primary users of ASTM WK33788. All parties interested in aiding the development of gaseous fuels standards are encouraged to join Committee D03.
ASTM International welcomes and encourages participation in the development of its standards. For more information on becoming an ASTM member, visit http://www.astm.org/JOIN.
ASTM International is one of the largest international standards development and delivery systems in the world. ASTM International meets the World Trade Organization (WTO) principles for the development of international standards: coherence, consensus, development dimension, effectiveness, impartiality, openness, relevance and transparency. ASTM standards are accepted and used in research and development, product testing, quality systems and commercial transactions.
