Atmospheric distillation of crude oil

The petroleum products obtained from the distillation process are light, medium, and heavy naphtha, kerosene, diesel, and oil residue.

Crude oil must first be desalted, by heating to a temperature of 100-150 °C and mixing with 4-10% fresh water to dilute the salt.

The remaining crude oil is passed through a side stripper which uses steam to separate kerosene.

The top product from the atmospheric distillation column is a mixture of hydrocarbon gases, e.g., methane, ethane, propane, butane, and naphtha vapors.

[3] Simulation helps in crude oil characterization so that thermodynamic and transport properties can be predicted.

[5] Dynamic models help in examining the relationships that could not be found by experimental methods (Ellner & Guckenheimer, 2006).
