3、 was corrected editorially in October 2015.INTRODUCTIONThis guide discusses the use of temperature and pressure volume correction factors for generalizedcrude oils, refined products, and lubricating oils, developed jointly by ASTM International, theAmerican Petroleum Institute (API) and the Energy I
4、nstitute.2The volume correction factors, in their basic form, are the output of a set of equations derived from,and based on, empirical data relating to the volumetric change of hydrocarbons over a range oftemperatures and pressures. Traditionally, the factors have been listed in tabular format call
5、ed thePetroleum Measurement Tables (hence the appearance of this term in the title), and published as anAPI Standard/Adjunct to IP 200/Adjunct to ASTM D1250. However, since the 1980 revision theactual standard has been a set of implementation procedures, not printed tables nor simply a set ofequatio
6、ns.This revised standard, API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTMD125004 (ADJD1250-E-PDF), establishes procedures for crude oils, liquid refined products, andlubricating oils, by which volume measurements taken at any temperature and pressure (within therange of the standard)
7、can be corrected to an equivalent volume at base/standard conditions, normally15C, 60F or 20C, by use of a volume correction factor (VCF). The standard, API MPMS Chapter11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004 (ADJD1250-E-PDF), also providesmethods for making conversions to alternate co
8、nditions from base conditions and to alternate basetemperatures. Densities can be corrected by using the inverse of the VCF.See Section 5 for a list of significant changes from Guide D125080 (provided in its entirety inAnnex A13).USAGE GUIDELINESThe revised standard, API MPMS Chapter 11.12004/Adjunc
9、t to IP 200/04/Adjunct to ASTMD125004 (ADJD1250-E-PDF), is effective upon the date of publication and supersedes the previousedition of the standard/adjunct(s). However, due to the nature of the changes in the revisedstandard/adjunct(s), it is recognized that guidance concerning an implementation pe
10、riod may beneeded in order to avoid disruptions within the industry and ensure proper application. As a result, itis recommended that the revised standard/adjunct(s) be used on all new applications no later than twoyears after the publication date (May 2004). An application for this purpose is defin
11、ed as the pointwhere the calculation is applied.Once the revised standard/adjunct(s) is implemented in a particular application, the previousstandard will no longer be used in that application.If an existing application complies with the previous standard/adjunct(s) (as referenced in AnnexA13), then
12、 it shall be considered in compliance with the revised standard/adjunct(s).However, the use of the API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTMD125004 (ADJD1250-E-PDF) remains voluntary, and the decision on when to utilize a standard isan issue that is subject to the negotiations b
13、etween the parties involved in the transaction.Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959. United States12007 UPDATESome minor modifications to the API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct toASTM D125004 (ADJD1250-E-PDF) have been
14、 issued in Addendum 1-2007. These modificationsto the adjunct necessitated a realignment withASTM Standard Guide D1250, hence an -07 version hasbeen approved and published.1. Scope1.1 The API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004 (ADJD1250-E-PDF) for tem-perature and pre
15、ssure volume correction factors for generalizedcrude oils, refined products, and lubricating oils, provides thealgorithm and implementation procedure for the correction oftemperature and pressure effects on density and volume ofliquid hydrocarbons. Natural gas liquids (NGLs) and liquefiedpetroleum g
16、ases (LPGs) are excluded from consideration. Thecombination of density and volume correction factors for bothtemperature and pressure is collectively referred to in thestandard/adjunct(s) as a Correction for Temperature and Pres-sure of a Liquid (CTPL). The temperature portion of thiscorrection is t
17、ermed the Correction for the effect of Tempera-ture on Liquid (CTL), also historically known as VCF (VolumeCorrection Factor). The pressure portion is termed the Correc-tion for the effect of Pressure on Liquid (CPL).As this standardwill be applied to a variety of applications, the output param-eter
18、s specified in this standard/adjunct(s) (CTL, Fp, CPL, andCTPL) may be used as specified in other standards.1.2 Including the pressure correction in API MPMS Chapter11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004(ADJD1250-E-PDF) represents an important change from the“temperature only” correct
19、ion factors given in the 1980 Petro-leum Measurement Tables. However, if the pressure is oneatmosphere (the standard pressure) then there is no pressurecorrection and the standard/adjunct(s) will give CTL valuesconsistent with the 1980 Petroleum Measurement Tables.1.3 API MPMS Chapter 11.12004/Adjun
20、ct to IP 200/04/Adjunct to ASTM D125004 (ADJD1250-E-PDF) coversgeneral procedures for the conversion of input data to generateCTL, Fp, CPL, and CTPL values at the user specified basetemperature and pressure (Tb, Pb). Two sets of procedures areincluded for computing volume correction factor: one set
21、fordata expressed in customary units (temperature in F, pressurein psig); the other for the metric system of units (temperaturein C, pressure in kPa or bar). In contrast to the 1980 PetroleumMeasurement Tables, the metric procedures require the proce-dure for customary units be used first to compute
22、 density at60F. This value is then further corrected to give the metricoutput. The metric procedures now incorporate the basetemperature of 20 C in addition to 15 C.1.4 The procedures recognize three distinct commoditygroups: crude oil, refined products, and lubricating oils. Aprocedure is also prov
23、ided for determining volume correctionfor special applications where the generalized commoditygroups parameters may not adequately represent the thermalexpansion properties of the liquid and a precise thermalexpansion coefficient has been determined by experiment.2.

Significance and Use4.1 The expanded limits of API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004(ADJD1250-E-PDF)
35、 are defined in a mixture of terms ofcustomary and metric units. Table 1 shows the defining limitsand their associated units in bold italics. Also shown in Table1 are the limits converted to their equivalent units (and, in thecase of the densities, other base temperatures).4.2 Note that only the pre
36、cision levels of the defining valuesshown in Table 1 are correct. The other values showingconverted units have been rounded to the significant digitsshown; as rounded values, they may numerically fall justoutside of the actual limits established by the defining values.4.3 Table 2 provides a cross-re
37、ference between the histori-cal table designations and the corresponding section in APIMPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct toASTM D125004 (ADJD1250-E-PDF). Note that procedureparagraphs 11.1.6.3 (U.S. customary units) and 11.1.7.3 (met-ric units) provide methods for correcting on-line
38、 densitymeasurements from live conditions to base conditions and thento compute CTPL factors for continuous volume corrections tobase conditions.4.4 When a glass hydrometer is used to measure the densityof a liquid, special corrections must be made to account for thethermal expansion of the glass wh
39、en the temperature isdifferent from that at which the hydrometer was calibrated. The1980 CTL Tables had generalized equations to correct glasshydrometer readings, and these corrections were part of theprinted odd-numbered tables. However, detailed procedures tocorrect a glass hydrometer reading are
40、beyond the scope ofAPIMPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct toASTM D125004 (ADJD1250-E-PDF). The user should referto the appropriate sections of API MPMS Chapter 9 or otherappropriate density/hydrometer standards for guidance.4.5 The set of correlations given in API MPMS Chapter11.12004
41、/Adjunct to IP 200/04/Adjunct to ASTM D125004(ADJD1250-E-PDF) is intended for use with petroleum fluidscomprising either crude oils, refined products, or lubricatingoils that are single-phase liquids under normal operatingconditions. The liquid classifications listed here are typicalterms used in th
42、e industry, but local nomenclature may vary.The list is illustrative and is not meant to be all-inclusive.4.6 Crude OilsA crude oil is considered to conform to thecommodity group Generalized Crude Oils if its density falls inthe range between approximately 10API to 100API. Crudeoils that have been s
43、tabilized for transportation or storagepurposes and whose API gravities lie within that range areconsidered to be part of the Crude Oil group. Also, aviation jetB (JP-4) is best represented by the Crude Oil correlation.4.7 Refined ProductsA refined product is considered toconform to the commodity gr
44、oup of Generalized RefinedProducts if the fluid falls within one of the refined productgroups. Note the product descriptors are generalizations. Thecommercial specification ranges of some products may placetheir densities partly within an adjacent class (for example, alow density diesel may lie in t
45、he jet fuel class). In such cases,the product should be allocated to the class appropriate to itsdensity, not its descriptor. The groups are defined as follows:4.7.1 GasolineMotor gasoline and unfinished gasolineblending stock with a base density range between approxi-mately 50API and 85API. This gr
46、oup includes substanceswith the commercial identification of: premium gasoline,unleaded gasoline, motor spirit, clear gasoline, low lead gas,motor gasoline, catalyst gas, alkylate, catalytic crackedgasoline, naphtha, reformulated gasoline, and aviation gaso-line.TABLE 1 Range LimitsAPhysical Units C
