ISO/TR 15403-2:2006 天然气.作为车辆压缩燃料使用的天然气.第2部分: 质量的规范

This Technical Report addresses the specifications of natural gas as a compressed fuel for vehicles as an addendum to ISO 15403-1. Specifically, it is intended to satisfy requests for quantitative data. The following are critical items regarding gas composition: water content; sulfur compounds; particulate matter; higher hydrocarbons; CO2; free oxygen; glycol/methanol; oil content corrosive components; This Technical Report pertains only to compressed natural gas as it enters the fuel containers on the vehicle. It does not apply to the natural gas delivered to a refuelling station. Any alteration of the natural gas supply composition to meet these specifications is clearly the responsibility of the refuelling station operator.

ASTM D4810-06(2011) 使用着色长度检测管对天然气中硫化氢的标准试验方法

The measurement of hydrogen sulfide in natural gas is important because of the gas quality specifications, the corrosive nature of H2S on pipeline materials, and the effects of H2S on utilization equipment. This test method provides inexpensive field screening of hydrogen sulfide. The system design is such that it may be used by nontechnical personnel with a minimum of proper training.1.1 This test method covers a procedure for a rapid and simple field determination of hydrogen sulfide in natural gas pipelines. Available detector tubes provide a total measuring range of 0.5 ppm by volume up to 40 % by volume, although the majority of applications will be on the lower end of this range (that is, under 120 ppm). 1.2 Typically, sulfur dioxide and mercaptans may cause positive interferences. In some cases, nitrogen dioxide can cause a negative interference. Most detector tubes will have a “precleanse” layer designed to remove certain interferences up to some maximum interferent level. Consult manufacturers' instructions for specific interference information. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

ASTM D4888-06 使用着色长度检测管对天然气中水蒸气的试验方法

The measurement of water vapor in natural gas is important because of the gas quality specifications, the corrosive nature of water vapor on pipeline materials, and the effects of water vapor on utilization equipment. This test method provides inexpensive field screening of water vapor. The system design is such that it may be used by nontechnical personnel with a minimum of proper training.1.1 This test method covers a procedure for rapid and simple field determination of water vapor in natural gas pipelines. Availabel detector tubes provide a total measuring range of 0.1 to 40 mg/L, although the majority of applications will be on the lower end of this range (that is, under 0.5 mg/L). At least one manufacturer provides tubes that read directly in pounds of water per million cubic feet of gas. See Note 1.1.2 Detector tubes are usually subject to interferences from gases and vapors other than the target substance. Such interferences may vary among brands because of the use of different detection methods. Consult manufacturer's instructions for specific interference information. Alcohols and glycols will cause interferences on some water vapor tubes because of the presence of the hydroxyl group on those molecules.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Standard Test Method for Water Vapor in Natural Gas Using Length-of-Stain Detector Tubes

ASTM D1988-06 用色斑长度检测管测定天然气中的硫醇的标准试验方法

The measurement of mercaptans in natural gas is important, because mercaptans are often added as odorants to natural gas to provide a warning property. The odor provided by the mercaptan serves to warn consumers (for example, residential use) of natural gas leaks at levels that are well below the flammable or suffocating concentration levels of natural gas in air. Field determinations of mercaptans in natural gas are important because of the tendency of the mercaptan concentration to fade over time. This test method provides inexpensive field screening of mercaptans. The system design is such that it may be used by nontechnical personnel, with a minimum of proper training.1.1 This test method covers a rapid and simple field determination of mercaptans in natural gas pipelines. Available detector tubes provide a total measuring range of 0.5 to 160 ppm by volume of mercaptans, although the majority of applications will be on the lower end of this range (that is, under 20 ppm). Besides total mercaptans, detector tubes are also available for methyl mercaptan (0.5 to 100 ppm), ethyl mercaptan (0.5 to 120 ppm), and butyl mercaptan (0.5 to 30 mg/M179; or 0.1 to 8 ppm).Note 18212;Certain detector tubes are calibrated in terms of milligrams per cubic metre (mg/M179;) instead of parts per million by volume. The conversion is as follows for 25176;C (77176;F) and 760 mm Hg.Equation 1 - mg/M179; = ppm X molecular weight/24.451.2 Detector tubes are usually subject to interferences from gases and vapors other than the target substance. Such interferences may vary among brands because of the use of different detection principles. Many detector tubes will have a precleanse layer designed to remove interferences up to some maximum level. Consult manufacturer's instructions for specific interference information. Hydrogen sulfide and other mercaptans are usually interferences on mercaptan detector tubes. See Section 5 for interferences of various methods of detection.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

The measurement of carbon dioxide in natural gas is important, because of the gas quality specifications, the corrosive nature of carbon dioxide on pipeline materials, and the affects of carbon dioxide on utilization equipment. This test method provides inexpensive field screening of carbon dioxide. The system design is such that it may be used by nontechnical personnel with a minimum of proper training.1.1 This test method covers a rapid and simple field determination of carbon dioxide in natural gas pipelines. Available detector tubes provide a total measuring range of 100 ppm (parts per million) up to 60 % by volume, although the majority of applications will be on the lower end of this range (that is, under 5 %). At least one manufacturer provides a special kit for measurements from 10 to 100 % CO2, but the normal 100-cc hand pump is not used. See Note 1. Note 18212;High-range carbon dioxide detector tubes will have measuring ranges in percent (%) CO2, and low-range tubes will be in parts per million (ppm). To convert percent to ppm, multiply by 10 000 (1 % = 10 000 ppm). 1.2 The values stated in SI units are regarded as standard. The inch-pound units in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Note 18212;Certain detector tubes are calibrated in terms of milligrams per cubic metre (mg/M3) instead of parts per million by volume. The conversion is as follows for 25°C (77°F) and 760 mm Hg. 1.2 Detector tubes are usually subject to interferences from gases and vapors other than the target substance.
