ISO 12213-3:1997 天然气 压缩因子的计算 第3部分:物理特性计算

This International Standard specifies methods for the calculation of compression factors of natural gases, natural gases containing a synthetic admixture and similar mixtures at conditions under which the mixture can exist only as a gas. This part of ISO 12213 specifies a method for the calculation of compression factors when the superior calorific value, relative density and carbon dioxide content are known, together with the relevant pressures and temperatures. If hydrogen is present, as is often the case for gases with a synthetic admixture, the hydrogen content also needs to be known. NOTE — In principle, it is possible to calculate the compression factor when any three of the parameters superior calorific value, relative density, carbon dioxide content (the usual three) and nitrogen content are known, but subsets including nitrogen content are not recommended. The method is primarily applicable to pipeline quality gases within the ranges of pressure p and temperature T at which transmission and distribution operations normally take place, with an uncertainty of about ±0.1 %. For wider-ranging applications the uncertainty of the results increases (see annex E). More detail concerning the scope and field of application of the method is given in part 1 of this International Standard.

ISO 12213-2:1997 天然气 压缩因子的计算 第2部分:摩尔代数运算分析

This International Standard specifies methods for the calculation of compression factors of natural gases, natural gases containing a synthetic admixture and similar mixtures at conditions under which the mixture can exist only as a gas. This part of ISO 12213 specifies a method for the calculation of compression factors when the detailed composition of the gas by mole fractions is known, together with the relevant pressures and temperatures. The method is applicable to pipeline quality gases within the ranges of pressure p and temperature T at which transmission and distribution operations normally take place, with an uncertainty of about ±0.1 %. It can be applied, with greater uncertainty, to wider ranges of gas composition, pressure and temperature (see annex E). More detail concerning the scope and field of application of the method is given in part 1 of this International Standard.

BS EN ISO 14111:1999 天然气 分析可追溯性指南

This International Standard provides general guidelines on the implementation and application of traceability concepts in the analysis of natural gas. Its purpose is to lay down the foundations for the development of specific traceability protocols in other International Standards for natural-gas analysis. NOTE —Besides the field of natural-gas analysis, this International Standard could also be useful as a guidance document in other areas of gas analysis and in related fields such as air quality measurement, vehicle emission monitoring and reference-gas mixture preparation.

Natural gas - Guidelines to traceability in analysis

BS EN ISO 6975:1997 天然气.延伸分析.气相色谱法

This International Standard describes the specifications for the quantitative analysis of the following components of natural gas: helium hydrogen argon oxygen nitrogen carbon dioxide saturated hydrocarbons from C1 to C5 hydrocarbon fractions from C6 upwards aromatic compounds as benzene and toluene The gas-chromatographic methods determine the components in the following ranges: oxygen: 0,001 % (n/n) to 0,5 % (n/n) helium: 0,001 % (n/n) to 0,5 % (n/n) hydrogen: 0,001 % (n/n) to 0,5 % (n/n) argon: 0,001 % (n/n) to 0,5 % (n/n) nitrogen: 0,001 % (n/n) to 40 % (n/n) carbon dioxide 0,001 % (n/n) to 40 % (n/n) methane: 50 % (n/n) to 100 % (n/n) ethane: 0,02 % (n/n) to 15 % (n/n) propane: 0,001 % (n/n) to 5 % (n/n) higher hydrocarbons: The method can measure hydrocarbon components from 10 (n/n) up to their maximum concentration, which is compatible with the requirement that the gas is free from hydrocarbon condensate at any pressure in the range 1 × 10kPa to 7×10kPa. This method is not intended for the determination of oxygen compounds (water vapour, methanol, glycols) or sulfur compounds. It is not possible to make unambiguous identifications of hydrocarbons above C6. Even where "spiking" a gas mixture with known components shows where they elute, it cannot be stated with certainty that such a component is the only one with that retention time. Unidentified components are classified according to the carbon number which the analysis indicates to be appropriate. While this is a necessary simplification, it does allow a reasonable quantitative value to be obtained. This method is intended for use in situations where the hexanes plus compositional breakdown and/or the complete analysis is desired. The method is not intended for dense phase gases whose pressure exceeds the cricondebar (critical condensation pressure), or for gas samples containing any measurable hydrocarbon condensate, liquid water or process fluid such as methanol or glycols (see ISO 6570-1 and ISO 10715). Gases which have been treated for transmission are unlikely to contain detectable levels of hydrocarbons above C12. Samples taken from nearer the well head, before the gas has reached gas treatment plants, may contain hydrocarbons to C16 or above.

ISO 10715:1997 天然气 取样指南

The purpose of this document is to provide concise guidelines for the collection, conditioning and handling of representative samples of processed natural gas streams. It also contains guidelines for sampling strategy, probe location and the handling and design of sampling equipment. It considers spot, composite (incremental) and continuous sampling systems. This document gives consideration to constituents such as oxygen, hydrogen sulfide, air, nitrogen and carbon dioxide in the gas stream. This document does not include sampling of liquid streams or streams with multiphase flow. Traces of liquid, such as glycol and compressor oil, if present, are assumed to be intrusive and not a part of the gas to be sampled. Their removal is desirable to protect the sampling and analytical equipment from contamination. This document can be used for custody transfer measurement systems and allocation measurement systems.

ASTM D6137-97(2012) 燃气脱硫系统用聚合衬垫的耐硫酸性的标准试验方法

1.1 This test method does not evaluate or correlate to areas within the scrubber or scrubbed gas streams at temperatures at or below the water dew point. 3.2 This test method is intended to evaluate the combined effects of heat and exposure to sulfuric acid upon a lining system as applied to a carbon steel substrate. It does not produce the thermal gradient through the lining that may exist in actual applications. Actual lining performance may also be affected by concurrent physical or mechanical effects and other chemicals that may be present in the flue gas. 3.3 This test method evaluates major failure modes of linings applied to square test panels that are cycled from room temperature to a designated elevated temperature. 3.4 The recommended test temperatures of 200??F (93??C) and 350??F (177??C) are based on typical maximum operating zone temperatures in flue gas desulfurizations systems. Other temperatures may be evaluated as desired. Cycling to lower temperatures, including freezing, may be considered if applicable. 3.5 The standard acid concentration for all tests is 208201;%, recognizing that the concentration will quickly rise to the equilibrium at the selected test temperature. 1.1 This test method is intended to evaluate the sulfuric acid resistance at elevated temperatures of polymer linings applied to carbon steel substrates subject to sulfuric acid attack. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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.
