ASTM D2158-97e1 液化石油(LP)气中残留物的标准测试方法

1.1 This test method covers the determination of the extraneous materials weathering above 38176;C that are present in liquefied petroleum gases.1.2 Liquefied petroleum gases that contain alcohols to enhance their anti-icing behaviour can give erroneous results by this test method.1.3 The result can be expressed in terms of measured volumes or indices derived from these volumes. In either case, the test method provides an indication of the quantity and nature of materials in the product that are substantially less volatile than the liquefied petroleum gas hydrocarbons.1.4 Although this test method has been used to verify cleanliness and lack of heavy contaminants in propane for many years, it may not be sensitive enough to protect some equipment from operational problems or increased maintenance. A more sensitive test, able to detect lower levels of dissolved contaminants, may be required for some applications.1.5 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. For specific precautionary statements, see 6.9.

ASTM D5305-97(2002) 测定液化石油气蒸气中乙硫醇的标准试验方法

1.1 This test method covers a rapid and simple procedure using length of stain tubes for field measurement of ethyl mercaptan in the vapor phase of LP-gas systems. Although length-of-stain tubes are available to detect ethyl mercaptan concentrations in the range of 0.5 to 120 parts per million volume (ppmv), this test method is specifically applicable to systems containing 5 ppmv or more of ethyl mercaptan in LP-gas vapors. Note 18212;A chromatographic technique can be used for more precise, quantitative determination of ethyl mercaptan in LP-gas.1.2 The values stated in SI (metric) units are to be regarded as the 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.

Standard Test Method for Determination of Ethyl Mercaptan in LP-Gas Vapor

ASTM D1265-97 液化石油(LP)气取样(手工法)

1.1 This practice covers the procedures for obtaining representative samples of liquefied petroleum gases such as propane, butane, or mixtures thereof, in containers other than those used in laboratory testing apparatus. These procedures are considered adequate for obtaining representative samples for all routine tests for LP gases required by Specification D1835 except analysis by Test Method D2163. They are not intended for obtaining samples to be used for compositional analysis. A sample procedure that avoids changes in composition must be used for compositional analysis. Note 1-Practice D3700 describes a recommended method for obtaining a representative sample of a hydrocarbon fluid and the subsequent preparation of that sample for laboratory analysis. 1.2 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 Practice for Sampling Liquefied Petroleum (LP) Gases (Manual Method)

ASTM D5287-97(2002) 气体燃料的自动抽样的标准操作规程

This practice should be used when and where a representative sample is required. A representative sample is necessary for accurate billing in custody transfer transactions. This practice is not intended to preempt existing contract agreements. Principles pertinent to this practice may be applied in most contractual agreements.1.1 This practice covers the collection of natural gases and their synthetic equivalents using an automatic sampler.1.2 This practice applies only to single-phase gas mixtures that vary in composition. A representative sample cannot be obtained from a two-phase stream.1.3 This practice includes the selection, installation, and maintenance of automatic sampling systems.1.4 This practice does not include the actual analysis of the acquired sample. Other applicable ASTM standards, such as Test Method D 1945, should be referenced to acquire that information.1.5 The selection of the sampling system is dependent on several interrelated factors. These factors include source dynamics, operating conditions, cleanliness of the source gases, potential presence of moisture and hydrocarbon liquids, and trace hazardous components. For clean, dry gas sources, steady source dynamics, and normal operating conditions, the system can be very simple. As the source dynamics become more complex and the potential for liquids increases, or trace hazardous components become present, the complexity of the system selected and its controlling logic must be increased. Similarly, installation, operation, and maintenance procedures must take these dynamics into account.1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.7 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.

This International Standard specifies a method for the determination of the residual matter in liquefied pet-roleum gases (LPG) that remains after evaporation at 105 ℃. This material, termed "oily residues", rep-resents those products that are deposited in vaporizers that are subject to a heat input greater than that of ambient evaporation.

Liquefied petroleum gases - Determination of oily residues - High-temperature method

ASTM UOP939-96 离子色谱法测定液化石油气中的碱性氮

This method is for determining basic nitrogen in liquefied petroleum gas (LPG). The method determines basic nitrogen species that are extractable by aqueous acid, including ammonia and alkyl amines, which typically adsorb on the stainless steel surface of a LPG cylinder. This method is limited to ammonia, primary amines containing four or less carbon atoms, secondary amines containing eight or less carbon atoms and tertiary amines with nine or less carbon atoms. All linear aliphatic substituents of the amine analytes must contain less than five carbon atoms. Combined nitrogen can be determined using UOP Method 936. Nitriles are not detected by this method. Amides and/or ionic sodium, if present at a concentration of 10 mass-ppm or greater, will interfere with the quantitation of ammonia. Potassium ions in the acid extract can also interfere with the detection of methylamine and ethylamine. The procedure yields quantitative basic nitrogen results in the range of 0.1 mass-ppm to 3 mass-%.

(See Test Method D 2158.)1.3 For calculating motor octane number, this practice is applicable only to mixtures containing 20 % or less of propene.1.4 For calculated motor octane number in method, this practice is based on mixtures containing only components shown in .1.5 The values stated in SI units are to be regarded as the standard.
