ASTM D6849-02 液化石油气试验方法用样品罐中液化石油气的储存和使用的标准实施规范

LPG samples can change composition during storage and use from preferential vaporization of lighter (lower molecular weight) hydrocarbon components, dissolved inert gases (N2, Ar, He, and so forth) and other dissolved gases/liquids (NH3, CO2, H2S, H2O, etc.). Careful selection of cylinder type, cylinder volume, and use of inert gas for pressurizing cylinders is required to ensure that composition changes are small enough to maintain the integrity of LPG when used as a QC reference material for various LPG test methods. Monitoring of ongoing precision and bias on QC materials using control chart techniques in accordance with Practice D 6299 can be used to establish the need for calibration or maintenance.1.1 This practice covers information for the storage and use of LPG samples in standard cylinders of the type used in sampling method, Practice D 1265 and floating piston cylinders used in sampling method, Practice D 3700.1.2 This practice is especially applicable when the LPG sample is used as a quality control (QC) reference material for LPG test methods, such as gas chromatography (GC) analysis (Test Method D 2163) or vapor pressure (Test Method D 6897) that use only a few mL per test, since relatively small portable Department of Transportation (DOT) cylinders (for example, 20 lb common barbecue cylinders) can be used. This practice can be applied to other test methods. However, test methods that require a large amount of sample per test (for example, manual vapor pressure Test Method D 1267) will require QC volumes in excess of 1000 L if stored in standard DOT cylinders or American Society of Mechanical Engineers (ASME) vessels.

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.

ASTM D1837-02a(2007) 液化石油气挥发性的标准试验方法

Volatility, expressed in terms of the 95 % evaporated temperature of the product, is a measure of the amount of least volatile components present in the product. Coupled with a vapor pressure limit, it serves to ensure essentially single-component products in the cases of commercial grades of propane and butane. When volatility is coupled with a vapor pressure limit which has been related to density, as in the case of the commercial PB-mixture, the combination serves to assure essentially two component mixtures for such fuels. When coupled with a proper vapor pressure limit, this measurement serves to assure that special-duty propane products will be composed chiefly of propane and propylene and that propane will be the major constituent.1.1 This test method is a measure of the relative purity of the various types of liquefied petroleum (LP) gases and helps to ensure suitable volatility performance. The test results, when properly related to vapor pressure and density of the product, can be used to indicate the presence of butane and heavier components in propane type LP-gas, and pentane and heavier components in propane-butane and butane type fuels. The presence of hydrocarbon compounds less volatile than those of which the LP-gas is primarily composed is indicated by an increase in the 95 % evaporated temperature.1.2 When the type and concentration of higher boiling components is required, chromatographic analysis should be used.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.

Information on the vapor pressures of liquefied petroleum gas products under temperature conditions from 37.8 to 70°C (100 to 158°F) is pertinent to selection of properly designed storage vessels, shipping containers, and customer utilization equipment to ensure safe handling of these products. Determination of the vapor pressure of liquefied petroleum gas is important for safety reasons to ensure that the maximum operating design pressures of storage, handling, and fuel systems will not be exceeded under normal operating temperature conditions. For liquefied petroleum gases, vapor pressure is an indirect measure of the most extreme low temperature conditions under which initial vaporization can be expected to occur. It can be considered a semi-quantitative measure of the amount of the most volatile material present in the product.1.1 This test method covers the determination of the gage vapor pressures of liquefied petroleum gas products at temperatures of 37.8176;C (100176;F) up to and including a test temperature of 70176;C (158176;F).1.2 The values stated in acceptable metric units are to be regarded as the standard.

ASTM UOP975-02 使用离子选择电极检测法通过氧化燃烧测定液烃和液化石油气中的氟含量

This method is for determining total fluorine in liquid hydrocarbons or liquefied petroleum gas (LPG) us-ing the Antek 9000F analyzer. It is applicable to liquid hydrocarbons with fluorine levels of 1 to 500 (m/v-ppm) with appropriate calibration standards. Higher concentrations can be analyzed by dilution in a solvent such as isooctane or toluene. The fluorine concentration in LPG can be measured down to 0.5 . This method is an alternative to UOP Method 619, which uses the potentially troublesome Wick-bold combustion apparatus.

This International Standard specifies the procedure to be used for obtaining samples of unrefrigerated liquefied petroleum gases (LPG). It is suitable for sampling from bulk containers, to provide samples for laboratory testing of products covered by ISO 9162. This International Standard is applicable for the provision of samples for compositional analysis by ISO 7941. It is not applicable for the provision of samples for trace analysis of low-boiling components. If trace analysis of low-boiling components is required, a variable-volume receiver such as that described in ASTM D 3700 should be used.
