Designation:D289220Standard 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 asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.1.6 WARNINGMercury has been designated by manyregulatory agencies as a hazardous substance that can causeserious medical issues.Mercury,or its vapor,has been dem-onstrated to be hazardous to health and corrosive to materials.Use Caution when handling mercury and mercury-containingproducts.See the applicable product Safety Data Sheet(SDS)for additional information.The potential exists that sellingmercury or mercury-containing products,or both,is prohibitedby local or national law.Users must determine legality of salesin their location.1.7 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific warning statements,see Section 10.1.8 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.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 June 1,2020.Published June 2020.Originallyapproved in 1970.Last previous edition approved in 2019 as D2892 19.DOI:10.1520/D2892-20.*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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D941 Test Method for Density and Relative Density(Spe-cific Gravity)of L
