ASTM D6667: Standard Test Method for Determination of Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases by Ultraviolet Fluorescence.
The ASTM D6667 test method is applicable for the determination of Total Sulfur in Gas/LPG samples, for fuel purposes, contributes to SOx emissions and can lead to corrosion in engine and exhaust systems. Some process catalysts used in petroleum and chemical refining can be poisoned by sulfur bearing materials in the feed stocks. This test method can be used to determine Sulfur in process feeds, to measure Sulfur in finished products, and can also be used for compliance determinations when acceptable to a regulatory authority.
Due to increasingly stringent legislation, car fuels have to be desulfurized to levels below 10 ppm, minimizing negative effects on the environment. Sulfur-containing emissions contribute to acid deposition (‘acid rain’).
This test method covers the determination of total volatile Sulfur in gaseous hydrocarbons and liquefied petroleum (LP) gases. It is applicable to analysis of natural, processed, and final product materials. Precision has been determined for Sulfur in gaseous hydrocarbons in the range of 1 mg/kg to 100 mg/kg and for Sulfur in LP gases in the range of 1 mg/kg to 196 mg/kg
Sample types: Gaseous Hydrocarbons, Natural Gas, LPG
Working range LPG: 1 – 196 mg/kg
Working range Gaseous hydrocarbons: 1 – 100 mg/kg
EST analytical solution:
The EST analytical NexiS and TS 7000 series models Total Sulfur analyzers are fully compliant with the ASTM D6667. Full automated analysis can be achieved with the GM 7000 Gas & LPG sample introduction module connected to one of the above analyzer models.
