Two types of crude oil from Hassira and Khurmala crude oil distilled into narrow fractions. The ranges of these narrow fractions are 10 ^ᵒC, starting from IBP to 350 °C.  Petroleum streams produced from distillation of crude oil such as gasoline, kerosene, diesel fuel, fuel oil, etc. are complex mixtures of large numbers of hydrocarbon components, such fractions are generally characterized in terms of small petroleum cuts, or pseudocomponents, which are identified primarily by their boiling point and specific gravity  due to their true boiling point curve (TBP), based on these two properties empirical correlations were derived to predict other components physical properties required for the process calculations. TBP distillation data and density of whole crude oil are used to perform the basic characterization and to obtain the product distribution of the crudes (using Aspen HYSHYS software).
