Designation:D716522Standard Practice forGas Chromatograph Based On-line/At-line Analysis forSulfur Content of Gaseous Fuels1This standard is issued under the fixed designation D7165;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1This practice is for the determination of gas phasesulfur-containing compounds in high methane content gaseousfuels such as natural gas using on-line/at-line instrumentation,and continuous fuel monitors(CFMS).It has been successfullyapplied to other types of gaseous samples including air,digester,landfill,and refinery fuel gas.The detection range forsulfur compounds,reported as picograms sulfur,based uponthe analysis of a 1 mL sample,is one hundred(100)to onemillion(1 000 000).This is equivalent to 0.1 to 1000 mg/m3.1.2 This practice does not purport to measure all sulfurspecies in a sample.Only gas phase compounds that aretransported to an instrument under the measurement conditionsselected are measured.1.3 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1072 Test Method for Total Sulfur in Fuel Gases byCombustion and Barium Chloride TitrationD1945 Test Method for Analysis of Natural Gas by GasChromatographyD3609 Practice for Calibration Techniques Using Perme-ation TubesD3764 Practice for Validation of the Performance of ProcessStream Analyzer SystemsD4084 Test Method for Analysis of Hydrogen Sulfide inGaseous Fuels(Lead Acetate Reaction Rate Method)D4150 Terminology Relating to Gaseous FuelsD4468 Test Method for Total Sulfur in Gaseous Fuels byHydrogenolysis and Rateometric ColorimetryD4626 Practice for Calculation of Gas ChromatographicResponse FactorsD4810 Test Method for Hydrogen Sulfide in Natural GasUsing Length-of-Stain Detector TubesD5504 Test Method for Determination of Sulfur Compoundsin Natural Gas and Gaseous Fuels by Gas Chromatogra-phy and ChemiluminescenceD6621 Practice for Performance Testing of Process Analyz-ers for Aromatic Hydrocarbon MaterialsD6122 Practice for Validation of the Performance of Multi-variate Online,At-Line,Field and Laboratory InfraredSpectrophotometer,and Raman Spectrometer Based Ana-lyzer SystemsD6228 Test Method for Determination of Sulfur Compoundsin Natural Gas and Gaseous Fuels by Gas Chromatogra-phy and Flame Photometric DetectionD7493 Test Method for Online Measurement of SulfurCompounds in Natural Gas and Gaseous Fuels by GasChromatograph and Electrochemical DetectionD7551 Test Method for Determination of Total VolatileSulfur in Gaseous Hydrocarbons and Liquefied Petroleum1This practice is under the jurisdiction of ASTM Committee D03 on GaseousFuels and is the direct responsibility of Subcommittee D03.12 on On-Line/At-LineAnalysis of Gaseous Fuels.Current edition approved Nov.1,2022.Published November 2022.Originallyapproved in 2006.Last previous edition approved in 2015 as D7165 10(2015).DOI:10.1520/D7165-22.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1Gases and Natural Gas by Ultraviolet FluorescenceD7833 Test Method for Determination of Hydrocarbons andNon-Hydrocarbon Gases in Gaseous Mixtures by GasChromatographyE594 Practice for Testing Flame Ionization Detectors Usedin Gas or Supercritical Fluid Chromatography2.2 ISO Standards:3ISO 7504 Gas Analysis-Vocabulary3.Terminology3.1 For definitions of general terms used in D03 GaseousFuels standards,refer to Terminology D4150.3.2 Definitions of Terms Specific to This Standard:3.2.1 near-real time monitoring systems
