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.

Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. Quantitative analysis of these odorized gases ensures that odorant injection equipment is performing to specification. The methane fraction of these fuel type gases are occasionally sold to distributors of natural gas.

Total sulfur content is determined from the total of individually quantified components. The values stated in inch-pound units are for information only.

This is equivalent to 0. The detector response to sulfur is equimolar for all sulfur compounds within the scope 1.

Applications

Low ppm amounts of sulfur odorants are added to natural gas and LP gases for safety purposes. The 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 Only compounds that are eluted through the selected column under the chromatographic conditions chosen are determined. It has been successfully applied to other types of gaseous samples including air, digester, landfill, and refinery fuel gas.

This is equivalent to 0. Thus, unidentified compounds are determined with equal precision to that of identified substances. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

Industry frequently requires measurement of sulfur in these fuel type gases to protect their catalyst investments.

The detector response to sulfur is equimolar for all sulfur compounds within the scope 1. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability r regulatory limitations prior to use. The values stated in inch-pound units are for information only.

Thus, unidentified compounds are determined with equal precision to that of identified substances. It has been successfully applied to other types of gaseous samples including air, digester, landfill, and refinery fuel gas. Many sources of natural and petroleum gases contain sulfur compounds that are odorous, corrosive, and poisonous to catalysts used in gaseous fuel processing. Some odorants are unstable and react to form compounds having lower odor thresholds.

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

Total sulfur content is determined sstm the total of individually quantified components. Analytical Methods — Gas chromatography GC is commonly used in the determination of fixed gas and organic composition of natural gas Test Method D 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.

Only compounds that are eluted through the selected column under the chromatographic conditions chosen are determined. Note 1— Dilution will reduce method precision. Refinery, landfill, sewage digester and other related fuel type gases inherently contain volatile sulfur compounds that are subject to federal, state, or local control.
