ASTM D2892-11a 原油蒸馏标准试验方法(15-理论板蒸馏柱)

This test method is one of a number of tests conducted on a crude oil to determine its value. It provides an estimate of the yields of fractions of various boiling ranges and is therefore valuable in technical discussions of a commercial nature. This test method corresponds to the standard laboratory distillation efficiency referred to as 15/5. The fractions produced can be analyzed as produced or combined to produce samples for analytical studies, engineering, and product quality evaluations. The preparation and evaluation of such blends is not part of this test method. This test method can be used as an analytical tool for examination of other petroleum mixtures with the exception of LPG, very light naphthas, and mixtures with initial boiling points above 400°C. 1.1 This test method covers the procedure for the distillation of stabilized crude petroleum (see Note 1) to a final cut temperature of 400°C Atmospheric Equivalent Temperature (AET). This test method employs a fractionating column having an efficiency of 14 to 18 theoretical plates operated at a reflux ratio of 5:1. Performance criteria for the necessary equipment is specified. Some typical examples of acceptable apparatus are presented in schematic form. This test method offers a compromise between efficiency and time in order to facilitate the comparison of distillation data between laboratories. Note 18212;Defined as having a Reid vapor pressure less than 82.7 kPa (12 psi). 1.2 This test method details procedures for the production of a liquefied gas, distillate fractions, and residuum of standardized quality on which analytical data can be obtained, and the determination of yields of the above fractions by both mass and volume. From the preceding information, a graph of temperature versus mass % distilled can be produced. This distillation curve corresponds to a laboratory technique, which is defined at 15/5 (15 theoretical plate column, 5:1 reflux ratio) or TBP (true boiling point). 1.3 This test method can also be applied to any petroleum mixture except liquefied petroleum gases, very light naphthas, and fractions having initial boiling points above 400°C. 1.4 This test method contains the following annexes and appendixes: 1.4.1 Annex A18212;Test Method for the Determination of the Efficiency of a Distillation Column, 1.4.2 Annex A28212;Test Method for the Determination of the Dynamic Holdup of a Distillation Column, 1.4.3 Annex A38212;Test Method for the Determination of the Heat Loss in a Distillation Column (Static Conditions), 1.4.4 Annex A48212;Test Method for the Verification of Temperature Sensor Location, 1.4.5 Annex A58212;Test Method for Determination of the Temperature Response Time, 1.4.6 Annex A68212;Practice for the Calibration of Sensors, 1.4.7 Annex A78212;Test Method for the Verification of Reflux Dividing Valves, 1.4.8 Annex A88212;Practice for Conversion of Observed Vapor Temperature to Atmospheric Equivalent Temperature (AET), 1.4.9 Appendix X18212;Test Method for Dehydration of a Sample of Wet Crude Oil, and 1.4.10 Appendix X28212;Practice for Performance Check. 1.5 The values stated in SI units are to be regarded as the standard.

ASTM D7691-11 感应耦合等离子体原子发射光谱法(ICP-AES)多元分析原油的标准试验方法

Most often determined trace elements in crude oils are nickel and vanadium, which are usually the most abundant; however, as many as 45 elements in crude oils have been reported. Knowledge of trace elements in crude oil is important because they can have an adverse effect on petroleum refining and product quality. These effects can include catalyst poisoning in the refinery and excessive atmospheric emission in combustion of fuels. Trace element concentrations are also useful in correlating production from different wells and horizons in a field. Elements such as iron, arsenic, and lead are catalyst poisons. Vanadium compounds can cause refractory damage in furnaces, and sodium compounds have been found to cause superficial fusion on fire brick. Some organometallic compounds are volatile which can lead to the contamination of distillate fractions, and a reduction in their stability or malfunctions of equipment when they are combusted. The value of crude oil can be determined, in part, by the concentrations of nickel, vanadium, and iron. Inductively coupled plasma-atomic emission spectrometry (ICP-AES) is a widely used technique in the oil industry. Its advantages over traditional atomic absorption spectrometry (AAS) include greater sensitivity, freedom from molecular interferences, wide dynamic range, and multi-element capability. See Practice D7260.1.1 This test method covers the determination of several elements (including iron, nickel, sulfur, and vanadium) occurring in crude oils. 1.2 For analysis of any element using wavelengths below 190 nm, a vacuum or inert gas optical path is required. 1.3 Analysis for elements such as arsenic, selenium, or sulfur in whole crude oil may be difficult by this test method due to the presence of their volatile compounds of these elements in crude oil; but this test method should work for resid samples. 1.4 Because of the particulates present in crude oil samples, if they do not dissolve in the organic solvents used or if they do not get aspirated in the nebulizer, low elemental values may result, particularly for iron and sodium. This can also occur if the elements are associated with water which can drop out of the solution when diluted with solvent. 1.4.1 An alternative in such cases is using Test Method D5708, Procedure B, which involves wet decomposition of the oil sample and measurement by ICP-AES for nickel, vanadium, and iron, or Test Method D5863, Procedure A, which also uses wet acid decomposition and determines vanadium, nickel, iron, and sodium using atomic absorption spectrometry. 1.4.2 From ASTM Interlaboratory Crosscheck Programs (ILCP) on crude oils data available so far, it is not clear that organic solvent dilution techniques would necessarily give lower results than those obtained using acid decomposition techniques. 1.4.3 It is also possible that, particularly in the case of silicon, low results may be obtained irrespective of whether organic dilution or acid decomposition is utilized. Silicones are present as oil field additives and can be lost in ashing. Silicates should be retained but unless hydrofluoric acid or alkali fusion is used for sample dissolution, they may not be accounted for. 1.5 This test method uses oil-soluble metals for calibration and does not purport to quantitatively determine insoluble particulates. Analytical results are particle size dependent and low results may be obtained for particles larger than a few micrometers. 1.6 The precision in Section 18 defines the concentration ranges cover......

ASTM D5853-11 原油倾点的标准试验方法

The pour point of a crude oil is an index of the lowest temperature of handleability for certain applications. This is the only pour point method specifically designed for crude oils. The maximum and minimum pour point temperatures provide a temperature window where a crude oil, depending on its thermal history, might appear in the liquid as well as the solid state. The test method can be used to supplement other measurements of cold flow behavior. It is especially useful for the screening of the effect of wax interaction modifiers on the flow behavior of crude oils.1.1 This test method covers two procedures for the determination of the pour point temperatures of crude oils down to −36°C. Procedure A provides a measure of the maximum (upper) pour point temperature and is described in 9.1. Procedure B provides a measure of the minimum (lower) pour point temperature and is described in 9.2. 1.2 The use of this test method is limited to use for crude oils. Pour point temperatures of other petroleum products can be determined by Test Method D97. 1.3 The values stated in SI units are to be regarded as standard.

ASTM D6377-10 测定原油蒸气压力的标准试验方法: VPCR_x(膨胀法)

Vapor pressure of crude oil at various V/Ls is an important physical property for shipping and storage. Note 28212;A vapor-liquid ratio of 0.02:1 (X = 0.02) mimics closely the situation of an oil tanker. Vapor pressure of crude oil is important to crude oil producers and refiners for general handling and initial refinery treatment. The vapor pressure determined by this test method at a vapor-liquid ratio of 4:1 (VPCR4) of crude oil at 37.8°C can be related to the vapor pressure value determined on the same material when tested by Test Method D323 (see Appendix X1). Chilling and air saturation of the sample prior to the vapor pressure measurement is not required. This test method can be applied in online applications in which an air saturation procedure prior to the measurement cannot be performed.1.1 This test method covers the use of automated vapor pressure instruments to determine the vapor pressure exerted in vacuum of crude oils. This test method is suitable for testing samples that exert a vapor pressure between 25 and 180 kPa at 37.8°C at vapor-liquid ratios from 4:1 to 0.02:1 (X = 4 to 0.02). Note 18212;This test method is suitable for the determination of the vapor pressure of crude oils at temperatures from 0 to 100°C and pressures up to 500 kPa, but the precision and bias statements (see Section 14) may not be applicable. 1.2 This test method allows the determination of vapor pressure for crude oil samples having pour points above 0°C. 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.

ASTM D3230-10 原油中含盐量的标准试验方法(电化学法)

This test method is used to determine the approximate chloride content of crude oils, a knowledge of which is important in deciding whether or not the crude oil needs desalting. The efficiency of the process desalter can also be evaluated. Excessive chloride left in the crude oil frequently results in higher corrosion rates in refining units and also has detrimental effects on catalysts used in these units. This test method provides a rapid and convenient means of determining the approximate content of chlorides in crude oil and is useful to crude oil processors.1.1 This test method covers the determination of the approximate chloride (salts) concentration in crude oil. The range of concentration covered is 0 to 500 mg/kg or 0 to 150 lb/1000 bbl as chloride concentration/volume of crude oil. 1.2 This test method measures conductivity in the crude oil due to the presence of common chlorides, such as sodium, calcium, and magnesium. Other conductive materials may also be present in the crude 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;Acceptable concentration units are g/m3 or PTB (lb/1000 bbl). 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

Standard Test Method for Salts in Crude Oil (Electrometric Method)

ASTM G205-10 测定原油耐腐蚀性的标准指南

In the absence of water, the crude oil is noncorrosive. The presence of sediment and water makes crude oil corrosive. Test Methods , , , and provide methods for the determination of the water and sediment content of crude oil. The corrosivity of crude oil containing water can be determined by a combination of three properties (Fig. 1) (1) : the type of emulsion formed between oil and water, the wettability of the steel surface, and the corrosivity of water phase in the presence of oil. Water and oil are immiscible but, under certain conditions, they can form emulsion. There are two kinds of emulsion: O/W and W/O. W/O emulsion (in which oil is the continuous phase) has low conductivity and is thus less corrosive; whereas O/W (in which water is the continuous phase) has high conductivity and, hence, is corrosive (see ISO 6614) (2). The conductivities of various liquids are provided in Table 1(3). The percentage of water at which W/O converts to O/W is known as the emulsion inversion point (EIP). EIP can be determined by measuring the conductivity of the emulsion. At and above the EIP, a continuous phase of water or free water is present. Therefore, there is a potential for corrosion. Whether water phase can cause corrosion in the presence of oil depends on whether the surface is oil wet (hydrophobic) or water wet (hydrophilic) (4-8). Because of higher resistance, an oil-wet surface is not susceptible to corrosion, but a water-wet surface is. Wettability can be characterized by measuring the contact angle or the conductivity (spreading method). In the contact angle method, the tendency of water to displace hydrocarbon from steel is measured directly by observing the behavior of the three phase system. The contact angle is determined by the surface tensions (surface free energies) of the three phases. A hydrocarbon-steel interface will be replaced by a water-steel interface if this action will result in an energy decrease of the system. To determine whether the surface is oil wet, mixed wet, or water wet, the angle at the oil-water-solid intersection is observed and measured. In the spreading method of determining wettability, the resistance between steel pins is measured. If a conducting phase (for example, water) covers (wets) the distance between the pins, conductivity between them will be high. On the other hand, if a nonconducting phase (for example, oil) covers (wets) the distance between the pins, the conductivity between them will be low. Dissolution of ingredients from crude oils may alter the corrosiveness of the aqueous phase. Based on how the corrosivity of the aqueous phase changes in its presence, a crude oil can be classified as corrosive, neutral, inhibitory, or preventive crude. Corrosiveness of the aqueous phase in the presence of oil can be determined by methods described in Test Method , Guide , Practice , Test Method , and NACE TM0172.1.1 This guide presents some generally accepted laboratory methodologies that are used for determining the corrosivity of crude oil. 1.2 This guide does not cover detailed calculations and methods, but rather a range of approaches that have found application in evaluating the corrosivity of crude oil. 1.3 Only those methodologies that have found wide acceptance in crude oil corrosivity evaluation are considered in this guide. 1.4 This guide does not address the change in oil/water ratio caused by accumulation of water at low points in a pipeline system. 1.5 This guide is intended to assist in the selection of methodologies that can be used for determining the corrosivity of crude oil under conditions in which water is present in the liquid state (typically up to 100°C). These conditions nor......
