Designation:D289215Standard Test Method forDistillation of Crude Petroleum(15-Theoretical PlateColumn)1This standard is issued under the fixed designation D2892;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers the procedure for the distillationof stabilized crude petroleum(see Note 1)to a final cuttemperature of 400 C Atmospheric Equivalent Temperature(AET).This test method employs a fractionating columnhaving an efficiency of 14 to 18 theoretical plates operated at areflux ratio of 5:1.Performance criteria for the necessaryequipment is specified.Some typical examples of acceptableapparatus are presented in schematic form.This test methodoffers a compromise between efficiency and time in order tofacilitate the comparison of distillation data between laborato-ries.NOTE1Defined as having a Reid vapor pressure less than 82.7 kPa(12 psi).1.2 This test method details procedures for the production ofa liquefied gas,distillate fractions,and residuum of standard-ized quality on which analytical data can be obtained,and thedetermination of yields of the above fractions by both mass andvolume.From the preceding information,a graph of tempera-ture versus mass%distilled can be produced.This distillationcurve corresponds to a laboratory technique,which is definedat 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 petroleummixture 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 andappendixes:1.4.1 Annex A1Test Method for the Determination of theEfficiency of a Distillation Column,1.4.2 Annex A2Test Method for the Determination of theDynamic Holdup of a Distillation Column,1.4.3 Annex A3Test Method for the Determination of theHeat Loss in a Distillation Column(Static Conditions),1.4.4 Annex A4Test Method for the Verification of Tem-perature Sensor Location,1.4.5 Annex A5Test Method for Determination of theTemperature Response Time,1.4.6 Annex A6Practice for the Calibration of Sensors,1.4.7 Annex A7Test Method for the Verification of RefluxDividing Valves,1.4.8 Annex A8Practice for Conversion of Observed Va-por Temperature to Atmospheric Equivalent Temperature(AET),1.4.9 Appendix X1Test Method for Dehydration of aSample of Wet Crude Oil,and1.4.10 Appendix X2Practice for Performance Check.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specificwarning statements,see Section 10.1.7 WARNINGMercury has been designated by manyregulatory agencies as a hazardous material that can causecentral nervous system,kidney and liver damage.Mercury,orits vapor,may be hazardous to health and corrosive tomaterials.Caution should be taken when handling mercury andmercury containing products.See the applicable product Ma-terial Safety Data Sheet(MSDS)for details and EPAswebsitehttp:/www.epa.gov/mercury/faq.htmfor addi-tional information.Users should be aware that selling mercuryand/or mercury containing products into your state or countrymay be prohibited by law.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.08 on Volatility.Current edition approved April 1,2015.Published April 2015.Originallyapproved in 1970.Last previous edition approved in 2013 as D2892 13.DOI:10.1520/D2892-15.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.Referenced Documents2.1 ASTM Standards:2D941 Test Method for Density and Relative Density(Spe-cific Gravity)of Liquids by Lipkin Bicapillary Pycnom-eter3D1217 Test Method for Density and Relative Density(Spe-cific Gravity)of Liquids by Bingham PycnometerD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD2887 Test Method for Boiling Range Distribution of Pe-troleum Fractions by Gas ChromatographyD3710 Test Method for Boiling Range Distribution of Gaso-line and Gasoline Fractions by Gas Chromatography(Withdrawn 2014)4D4006 Test Method for Water in Crude Oil by DistillationD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice fo
