ASTM D2892-11a

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:D2892–11 Designation: D2892 – 11a
Standard Test Method for
Distillation of Crude Petroleum (15-Theoretical Plate
1
Column)
This standard is issued under the fixed designation D2892; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval.A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 Thistestmethodcoverstheprocedureforthedistillationofstabilizedcrudepetroleum(seeNote1)toafinalcuttemperature
of 400°CAtmospheric 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

and time in order to facilitate the comparison of distillation data between laboratories.
NOTE 1—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) orTBP(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 A1—Test Method for the Determination of the Efficiency of a Distillation Column,
1.4.2 Annex A2—Test Method for the Determination of the Dynamic Holdup of a Distillation Column,
1.4.3 Annex A3—Test Method for the Determination of the Heat Loss in a Distillation Column (Static Conditions),
1.4.4 Annex A4—Test Method for the Verification of Temperature Sensor Location,
1.4.5 Annex A5—Test Method for Determination of the Temperature Response Time,
1.4.6 Annex A6—Practice for the Calibration of Sensors,
1.4.7 Annex A7—Test Method for the Verification of Reflux Dividing Valves,
1.4.8 Annex A8—Practice for Conversion of Observed Vapor Temperature to Atmospheric Equivalent Temperature (AET),
1.4.9 Appendix X1—Test Method for Dehydration of a Sample of Wet Crude Oil, and
1.4.10 Appendix X2—Practice for Performance Check.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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 Section 10.
