Industry frequently requires measurement of sulfur in these fuel type gases to protect their catalyst investments. Link to Active This link will always route to the current Active version of the standard.

Note 1— Dilution will reduce method precision.

Analytical Methods — Gas chromatography GC is commonly used in the determination of fixed gas and organic composition of natural gas Test Method D This is equivalent to 0. 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. Historical Version s – view previous versions of standard Translated Version s: Total sulfur content is determined from the total of individually quantified components.

Thus, unidentified compounds are determined dd equal precision to that of identified substances.

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.

The values stated in inch-pound units are for information only. Some odorants are unstable and react to form compounds having lower odor thresholds. Refinery, landfill, sewage digester and other related fuel type gases inherently contain volatile sulfur compounds that are subject to federal, state, or local control.

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

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. Quantitative analysis of these odorized gases ensures that odorant injection equipment is performing to specification. Low ppm amounts of sulfur odorants are added to natural gas and LP gases for safety purposes. Many sources of natural and petroleum gases contain sulfur compounds that are odorous, corrosive, and poisonous to catalysts used in gaseous fuel processing.

The methane fraction of these fuel type gases are occasionally sold to distributors of natural gas. 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, landfill, and refinery fuel gas.

Only 55504 that are eluted through the selected column under the chromatographic conditions chosen are determined.

Historical Version s – view previous versions of standard. The detector response to sulfur is equimolar for all sulfur compounds within the scope 1. Total sulfur content is determined from the total of individually quantified components. The detection range for sulfur compounds, reported as picograms sulfur, is ten 10 to one million 1 Asttm detection range for sulfur compounds, reported as picograms sulfur, is ten 10 to one million 1 The detector wstm to sulfur is equimolar for all sulfur compounds within the scope atsm.

Thus, unidentified compounds are determined with equal precision to that of identified substances.

Applications

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. This is equivalent to 0. Only compounds that are eluted through the selected column under the chromatographic conditions chosen are determined.
