Thus, unidentified compounds are determined with equal precision to that of identified substances. Low ppm amounts of sulfur odorants are added to natural gas and LP gases for safety purposes. 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.

Total sulfur content is awtm from the total of individually quantified components.

Active view current version of standard. The values stated in inch-pound units are for information only. It has been aztm applied to other types of gaseous samples including air, digester, landfill, and refinery fuel 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.

Applications

Industry frequently requires measurement of sulfur in these ast type gases to protect their catalyst investments. The detector response to sulfur is equimolar for all sulfur compounds within the scope 1. The detector response to sulfur is equimolar for all sulfur compounds within the scope 1. Only compounds that are eluted through the selected column under the chromatographic conditions chosen are determined.

The values stated in inch-pound units are for information only. The detection range for sulfur compounds, reported as picograms sulfur, is ten 10 to one million 1 Total sulfur content is determined from the total of individually quantified components.

Thus, unidentified compounds are determined with equal precision to that of identified substances. 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. Some odorants are unstable and react to form compounds having lower odor thresholds.

The methane fraction of these fuel type gases are occasionally sold to distributors of natural gas. Note 1— Dilution will reduce method precision. Link to Active This link will always route to the current Active version of the standard.

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

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.

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. Refinery, landfill, sewage digester and other related fuel type gases inherently contain volatile sulfur compounds that are subject to federal, state, or local control. It has been successfully applied to other types of gaseous samples including air, digester, landfill, and refinery fuel gas.
