Historical Version s – view previous versions of standard.
Many sources of natural and petroleum gases contain sulfur compounds that are odorous, corrosive, and poisonous to catalysts used in gaseous fuel processing. Low 504 amounts of sulfur odorants are added to natural gas and LP gases for safety purposes. Some odorants are unstable and react to form compounds having lower odor thresholds.
Quantitative analysis of these odorized gases ensures that odorant injection equipment is performing to specification. Although not intended for application to gases other than natural gas and related fuels, this test method has been successfully applied to fuel type gases including refinery, landfill, cogeneration, and sewage digester gas.
Refinery, landfill, sewage digester and other related fuel type gases inherently contain volatile sulfur compounds that are subject to federal, state, or local control. The methane fraction of these fuel type gases are occasionally sold to distributors of natural gas.
For these reasons, both regulatory agencies and production and distribution facilities may require the accurate determination of sulfur to satisfy regulatory, production or distribution requirements. Fuel gases are also used in energy production or are converted to new products using catalysts that are poisoned by excessive sulfur in the feed gas. Industry frequently requires measurement of sulfur in these fuel type gases to protect their catalyst investments.
ASTM D – Determination of Sulfur Compounds in Natural Gas by Chemiluminescence Detection
Analytical Methods — Gas chromatography GC is commonly used in the determination of fixed gas and organic composition of natural gas Test Method D It has been successfully applied to other types of gaseous samples including air, digester, landfill, and refinery fuel gas.
The detection range for sulfur compounds, reported as picograms sulfur, is ten 10 to one million 1 This is equivalent to 0. Note 1— Dilution will reduce method precision. Only compounds that are eluted through the selected column under the chromatographic conditions chosen are determined. The detector response to sulfur is equimolar for all 55044 compounds within the scope 1.
Thus, unidentified compounds are determined with equal precision to that of identified substances. Total sulfur content is determined from the total of individually quantified components.
