2.4.3. ASTM DistillationThe distillation of petroleum cuts is done in a simple distillation apparatuswhich does not have a fractionation column. For light cuts (gasoline, kerosene,diesel and heating oil) the distillation is run at atmospheric pressure underASTM D86 test. For heavier fractions an ASTM D1160 test at reducedpressure is employed.2.4.4. Simulated Distillation by Gas ChromatographyThe boiling point distribution of the whole crude oil can be determined byan injection of the sample in a gas chromatograph which separates thehydrocarbons in boiling point order. The retention time is related to theboiling point through a calibration curve. The results of this test arecomparable to the true boiling point tests. In addition, the boiling pointdistribution of light and heavy petroleum cuts can also be done by gaschromatography. One of the standards methods of measurements isASTM D5307.
