Standard Test Method for Determining Filterability of Middle Distillate Fuel Oils

ASTM D6021-12 通过复式顶端空间提取和硫比率测定的残留燃料总硫化氢测量的标准试验方法

Residual fuel oils can contain H2S in the liquid phase, and this can result in hazardous vapor phase levels of H2S in storage tank headspaces. The vapor phase levels can vary significantly according to the headspace volume, fuel temperature, and agitation. Measurement of H2S levels in the liquid phase provides a useful indication of the residual fuel oil’s propensity to form high vapor phase levels, and lower levels in the residual fuel oil will directly reduce risk of H2S exposure. It is critical, however, that anyone involved in handling fuel oil, such as vessel owners and operators, continue to maintain appropriate safety practices designed to protect the crew, tank farm operators and others who can be exposed to H2S. The measurement of H2S in the liquid phase is appropriate for product quality control, while the measurement of H2S in the vapor phase is appropriate for health and safety purposes. This test method was developed so refiners, fuel terminal operators and independent testing laboratory personnel can analytically measure the amount of H2S in the liquid phase of residual fuel oils. Note 18212;Test Method D6021 is one of three test methods for quantitatively measuring H2S in residual fuels: 1) Test Method D5705 is a simple field test method for determining H2S levels in the vapor phase. 2) Test Method D7621 is a rapid test method to determine H2S levels in the liquid phase. H2S concentrations in the liquid and vapor phase attempt to reach equilibrium in a static system. However, this equilibrium and the related liquid and vapor concentrations can vary greatly depending on temperature and the chemical composition of the liquid phase. A concentration of 1 mg/kg (μg/g) (ppmw) of H2S in the liquid phase of a residual fuel can typically generate an actual gas concentration of >50 to 100 μL/L(ppmv) of H2S in the vapor phase, but the equilibrium of the vapor phase is disrupted the moment a vent or access point is opened to collect a sample. Note 28212;Because of the reactivity, absorptivity, and volatility of H2S any measurement method only provides an H2S concentration at a given moment in time.1.1 This test method covers a method suitable for measuring the total amount of hydrogen sulfide (H2S) in heavy distillates, heavy distillate/residual fuel blends, or residual fuels as defined in Specification D396 Grade 4, 5 (Light), 5 (Heavy), and 6, when the H2S concentration in the fuel is in the 0.01 to 100 μg/g (ppmw) range. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. For specific warning statements, see 7.5, 8.2, 9.2, 10.1.4, and 11.1.

5.1 Gasoline-range olefinic hydrocarbons have been demonstrated to contribute to photochemical reactions in the atmosphere, which result in the formation of photochemical smog in susceptible urban areas. 5.2 The California Air Resources Board (CARB) has specified a maximum allowable limit of total olefins in motor gasoline. This necessitates an appropriate analytical test method for determination of total olefins to be used both by regulators and producers. 5.3 This test method compares favorably with Test Method D1319 (FIA) for the determination of total olefins in motor gasolines. It does not require any sample preparation, has a comparatively short analysis time of about 10 min, and is readily automated. Alternative methods for determination of olefins in gasoline include Test Methods D6839 and D6296. 1.1 This test method covers the determination of the total amount of olefins in blended motor gasolines and gasoline blending stocks by supercritical-fluid chromatography (SFC). Results are expressed in terms of mass % olefins. The application range is from 18201;mass8201;% to 258201;mass % total olefins. 1.2 This test method can be used for analysis of commercial gasolines, including those containing varying levels of oxygenates, such as methyl tert/butyl ether (MTBE), diisopropyl ether (DIPE), methyl tert/amyl ether (TAME), and ethanol, without interference. Note 1: This test method has not been designed for the determination of the total amounts of saturates, aromatics, and oxygenates. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

The four grades of fuel are intended for use in various types of fuel-oil-burning industrial equipment under various climatic and operating conditions. These fuels are not intended for use in residential heaters, small commercial boilers, combustion engines, or marine applications, 1.1.1 Grades RFO4, RFO5L, RFO5H, and RFO6 are used lubricating oil blends, with or without distillate or residual fuel oil, or both, of increasing viscosity and are intended for use in industrial burners equipped to handle these types of recycled fuels. Note 18212;For information on the significance of the terminology and test methods used in this specification, see Appendix X1. 1.2 This specification is for use in contracts for the purchase of fuel oils derived from used lubricating oil and for the guidance of consumers of such fuels. This specification does not address the frequency with which any particular test must be run. 1.3 Nothing in this specification shall preclude observance of national or local regulations, which can be more restrictive. In some jurisdictions, used oil is considered a hazardous waste and fuels from used oil are required to meet certain criteria before use as a fuel. Note 28212;For United States federal requirements imposed on used oil generators, transporters and transfer facilities, reprocessors, marketers, and burners, see 40 CFR 279. Note 38212;The generation and dissipation of static electricity can create problems in the handling of distillate burner fuel oils. For more information on the subject, see Guide D 4865. 1.4 The values stated in SI units are to be regarded as standard; non-SI units, when given, are for information only.

Standard Test Method for Hydroperoxide Number of Aviation Turbine Fuels by Voltammetric Analysis

ASTM D6468-08 中间馏分燃料高温度稳定性的标准试验方法

This test method provides an indication of thermal oxidative stability of distillate fuels when heated to high temperatures that simulate those that may occur in some types of recirculating engine or burner fuel delivery systems. Results have not been substantially correlated to engine or burner operation. The test method can be useful for investigation of operational problems related to fuel thermal stability. When the test method is used to monitor manufacture or storage of fuels, changes in filter rating values can indicate a relative change in inherent stability. Storage stability predictions are more reliable when correlated to longer-term storage tests, for example, Test Method D 4625, or other lower temperature, long-term tests. When fuel samples are freshly produced, aging for 180 min, instead of the traditional 90-min interval, tends to give a result correlating more satisfactorily with the above methods (see Appendix X2). The test method uses a filter paper with a nominal porosity of 11 μm, which will not capture all of the sediment formed during aging but allows differentiation over a broad range. Reflectance ratings are also affected by the color of filterable insolubles, which may not correlate to the mass of the material filtered from the aged fuel sample. Therefore, no quantitative relationship exists between the pad rating and the gravimetric mass of filterable insolubles.1.1 This test method covers relative stability of middle distillate fuels under high temperature aging conditions with limited air exposure. This test method is suitable for all No. 1 and No. 2 grades in Specifications D 396, D 975, D 2880, and D 3699. It is also suitable for similar fuels meeting other specifications. 1.2 This test method is not suitable for fuels whose flash point, as determined by Test Methods D 56, D 93, or D 3828, is less than 38°C. This test method is not suitable for fuels containing residual oil. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1 Exception8212;The maximum vacuum includes inch-pound units in 6.5 and 11.2. 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 D6423-08 乙醇、改性燃料乙醇和燃料乙醇Ed75-ed85的Phe测定的标准试验方法

The acid strength, as measured by pHe, is a good predictor of the corrosion potential of ethanol fuels. It is preferable to total acidity because total acidity does not measure acid strength; overestimates the contribution of weak acids, such as carbonic acid; and may underestimate the corrosion potential of low concentrations of strong acids, such as sulfuric acid.1.1 This test method covers a procedure to determine a measure of the acid strength of high ethanol content fuels. These include ethanol, denatured fuel ethanol, and fuel ethanol (Ed75-Ed85). The test method is applicable to fuels containing nominally 70 volume % ethanol, or higher, as described in Specifications D 4806 and D 5798. 1.2 Acid strength as measured in this test method is defined as pHe. A pHe value for alcohol solutions is not comparable to pH values of water solutions. For example, a 1.5×10-5 M (18 ppm) solution of H2SO4 gives a pH of about 5.5 in water solution, but, depending on buffering strength, a pHe as low as 1 to 2 in unadditized alcohol fuel. 1.3 The value of pHe measured will depend somewhat on the fuel blend, the stirring rate, and the time the electrode is in the fuel. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 D6021-06 通过复式顶端空间萃取和硫比率测定的残留燃料总硫化氢测量的标准试验方法

Excessive levels of hydrogen sulfide in the vapor phase above residual fuel oils in storage tanks may result in health hazard, OSHA limits violation, and public complaint. An additional concern is corrosion that can be caused by the presence of H2S during refining and other production activities. Control measures to maintain safe levels of H2S require a consistent method for the assessment of potentially hazardous levels of H2S in fuel oils. (Warning8212;H2S is a highly toxic substance. Extreme care must be used in the sampling and handling of samples that are suspected of containing high levels of H2S.) A concentration of 0.1 μg/g (ppmw) of H2S in the liquid phase of a No. 4, 5, or 6 residual fuel oil can generate an actual gas concentration of 10 to 100 μL/L (ppmv) of H2S in the vapor phase; therefore an accurate analytical method is required to determine the total H2S concentration of these residual fuel oils. This test method was developed so refiners, fuel terminal operators, and independent testing laboratory personnel can analytically measure the amount of H2S in residual fuel oils. Test Method D 5705 provides a simple and consistent field test method for the rapid determination of H2S in the residual fuel oils storage tank vapor phase. However, it does not necessarily simulate the vapor phase H2S concentration of a fuel storage tank nor does it provide any indication of the liquid phase H2S concentration. This test method provides a quantitative measure of a residual fuel oils liquid phase H2S concentration. It requires a laboratory and a skilled operator to perform the test but gives a more quantitative indication of potential H2S exposure than Test Method D 5705. Note 18212;Because of the reactivity, absorptivity, and volatility of H2S any measurement method only provides an H2S concentration at a given moment in time.1.1 This test method covers a method suitable for measuring the total amount of hydrogen sulfide (H2S) in heavy distillates, heavy distillate/residual fuel blends, or residual fuels as defined in Specification D 396 Grade 4, 5 (Light), 5 (Heavy), and 6, when the H2S concentration in the fuel is in the 0.01 to 100 g/g (ppmw) range.1.2 The values stated in SI units are to be regarded as the standard.
