What is SimDist?

Simulated distillation (SimDist) is a gas chromatography (GC) technique which separates individual hydrocarbon components in the order of their boiling points, and is used to simulate the time-consuming laboratory-scale physical distillation procedure known as true boiling point (TBP) distillation.

What is SimDis analysis?

Simulated distillation (SimDis) is a gas chromatographic technique used to simulate the results of a distillation tower, separating crudes or other multicomponent blends into component fractions by boiling points. The expected boiling point range of the samples being tested will determine which method is best to use.

What is a simulated distillation?

What is Simulated Distillation? Simulated distillation is used to determine the true boiling point distribution of crude oil and petroleum refining fractions by gas chromatography. It is frequently used as an alternative to time consuming and labor intensive physical distillations.

What is ASTM D2892?

ASTM D2892-20. June 1, 2020. Standard Test Method for Distillation of Crude Petroleum (15-Theoretical Plate Column) 1.1 This test method covers the procedure for the distillation of stabilized crude petroleum (see Note 1) to a final cut temperature of 400 °C Atmospheric Equivalent Temperature (AET).

Why is ASTM distilled?

ASTM Distillation refers to a diverse group of different ASTM International standards. These different ASTM standards all use the distillation (volatility) characteristics of the substrate in determining the adherence (or not) of the substrate to the standard.

What is TBP cut point?

Using a crude TBP curve, cut points are defined as the temperatures that represent the limits of a distillate fraction, as illustrated in Figure 4.11. Boiling ranges between the cut points represent distillate products, such as naphtha, kerosene, light gas oil, etc.

What is ASTM distillation curve?

This curve is plotted between the percentage of the volume of fuel evaporated from the flask and the recorded temperature after every 10cc of condensate is called the ASTM distillation curve.

What is ASTM Distillation test?

ASTM Distillation is a standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure.
