ASTM UOP202-14 轻质石油馏分和液化石油气(LPG)中的二硫化物

This method is for determining disulfide sulfur in gasoline, liquefied petroleum gas (LPG), and other light petroleum distillates. Part A of the method, an acid stirring procedure, is used for low molecular weight disulfides usually found in LPG and for distillates that do not contain tertiary disulfides. Because of its rapidity, the acid stirring procedure is recommended for routine work where tertiary disulfides are not a factor. Part B of the method, an acid reflux procedure, is reserved for samples containing tertiary disulfides. This method is applicable to samples containing a disulfide sulfur concentration of 10 mass-ppm or greater.

This European Standard covers the requirements for the design, manufacture, testing and marking of LPG dispensers for automotive LPG filling stations with a maximum allowable pressure of 25 bar (2500 kPa), where the piping has a maximum DN 40 and any vessel fitted has a volume less than 2 l. This European Standard covers the requirements for the LPG parts in multi-fuel dispensers. This European Standard does not cover dispensers with integral pumps. This European Standard may also be used for piping greater than DN 40 and/or vessels greater than 2 l, but then the PED [20] should also be consulted. This European Standard does not include any requirement for metering performance.

The values given in parentheses are provided for information only. 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 D7756-13 使用带有液态柱上注射的气相色谱法测定液化石油 (LP) 残留物的标准试验方法

5.1 Control over the residue content as specified in Specification D1835 is of considerable importance in end-use applications of LPG. Oily residue in LPG is contamination which can occur during production, transportation, or storage. 5.2 This test method is quicker and much more sensitive than manual methods, such as Test Method D2158, which is based on evaporation of large sample volumes followed by visual or gravimetric estimation of residue content. 5.3 This test method provides enhanced sensitivity in measurements of heavier (oily) residues, with a quantification limit of 10 mg/kg total residue. 5.4 This test method gives both quantitative results and information about contaminant composition such as boiling point range and fingerprint, which can be very useful in tracing the source of a particular contaminant. 1.1 This test method covers the determination, by gas chromatography, of soluble hydrocarbon materials, sometimes called “oily residue,” which can be present in Liquefied Petroleum (LP) Gases and which are substantially less volatile than the LPG product. 1.2 This test method quantifies, in the range of 10 to 600 mg/kg (ppm mass), the residue with a boiling point between 174°C and 522°C (C10 to C40) in LPG. Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected. 1.3 Appendix X3 and Appendix X4 describe additional applications which could be performed based on the hardware and procedures described in this test method. Appendix X3 describes a test procedure for expanding the analysis range to benzene, and Appendix X4 describes a test procedure for the analysis of diisopropanolamine in LPG. 1.4 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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.

ASTM D6849-13 液化石油气试验方法用样品罐中液化石油气(LPG)的储存和使用的标准实施规程

5.1 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. 5.2 Monitoring of ongoing precision and bias on QC materials using control chart techniques in accordance with Practice D6299 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 D1265 and floating piston cylinders used in sampling method, Practice D3700. 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 D2163) or vapor pressure (Test Method D6897) 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 D1267) will require QC volumes in excess of 1000 L if stored in standard DOT cylinders or American Society of Mechanical Engineers (ASME) vessels.

ASTM D2420-13 液化石油(LP)气中硫化氢的标准试验方法(醋酸铅法)

4.1 Liquefied petroleum gases and their products of combustion must not be unduly corrosive to the materials with which they come in contact. The potential personnel exposure hazards of H2S also make the detection and measurement of hydrogen sulfide important, even in low concentrations. In addition, in some cases the odor of the gases shall not be objectionable. (See Specification D1835 and GPA 2140.) 1.1 This test method2 covers the detection of hydrogen sulfide in liquefied petroleum (LP) gases. The sensitivity of the test is about 4 mg/m3 (0.15 to 0.2 grain of hydrogen sulfide per 100 ft3) of gas. 1.2 The values stated in SI units are to be regarded as standard. The values given 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.

ASTM D2598-12 通过组分分析计算液化石油气的某些物理性质的标准实施规程

4.1 Vapor pressure is an important specification property of commercial propane, special duty propane, propane/butane mixtures, and commercial butane that assures adequate vaporization, safety, and compatibility with commercial appliances. Relative density, while not a specification criterion, is necessary for determination of filling densities and custody transfer. The motor octane number (MON) is useful in determining the products' suitability as a fuel for internal combustion engines. 1.1 This practice covers, by compositional analysis, the approximate determination of the following physical characteristics of commercial propane, special-duty propane, commercial propane/butane mixtures, and commercial butane (covered by Specification D1835): vapor pressure, relative density, and motor octane number (MON). 1.1.1 This practice is not applicable to any product exceeding specifications for nonvolatile residues. (See Test Method D2158.) 1.1.2 For calculating motor octane number, this practice is applicable only to mixtures containing 208201;% or less of propene. 1.1.3 For calculated motor octane number, this practice is based on mixtures containing only components shown in Table 1.TABLE 1 Factors for Determining the Physical Characteristics of LP-GasesA Component Vapor Pressure Blend Factor, kPa-gage (PSIG) at 37.8°C (100°F) Relative Density at 15.6°C (60°F) MON Blend Value Methane 17547 (2545) 0.3 .8201;.8201;.
