1.1 This test method covers the procedure for the distillation of stabilized crude petroleum 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.

1.2 This test method details procedures for the production of a liquified 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 liquified petroleum gases, very light naphthas, and fractions having initial boiling points above 400°C.

1.4 This test method contains the following Annexes:

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 standard. The values given in parentheses are provided 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 precautionary notes, see Section 10.
