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.

Note 1— Dilution will reduce method precision. Quantitative analysis of these odorized gases ensures that odorant injection equipment is performing to specification. This is equivalent to 0. Only compounds that are eluted through the selected column 55504 the chromatographic conditions chosen are determined. This is equivalent to 0.

ASTM D – Determination of Sulfur Compounds in Natural Gas by Chemiluminescence Detection

The methane fraction of these fuel type gases are occasionally sold to distributors of natural gas. R detection range for sulfur compounds, reported as picograms sulfur, is ten 10 to one million 1 The detection range for sulfur compounds, reported as picograms sulfur, is ten 10 to one million 1 Some odorants are unstable and react to form compounds having lower odor thresholds.

Many sources of natural and petroleum gases contain sulfur compounds that are odorous, corrosive, and poisonous to catalysts used in gaseous fuel processing. Referenced Documents purchase separately The documents listed below are referenced within the 55004 standard but are not provided as part of the standard. Industry frequently requires measurement of sulfur in these fuel type gases to protect their catalyst investments. Total sulfur content is determined from the total of individually quantified components.

Refinery, landfill, sewage digester and other related fuel type gases inherently contain volatile sulfur compounds 5540 are subject to federal, state, or local control. The values stated in inch-pound units are for information only. It has been successfully applied to other types of gaseous samples including air, digester, ast, and refinery fuel gas. Low ppm amounts of sulfur odorants are added to natural gas and LP gases for safety purposes.

Thus, unidentified compounds are determined with equal precision to that of identified substances. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Analytical Methods — Gas chromatography GC is commonly astk in the determination of fixed gas and organic composition of natural gas Test C D The detector response to sulfur is equimolar for all sulfur compounds within the scope 1.

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.
