Estimate equilibrium flash vaporization curves accurately

A computer program simplifies methods of true boiling point curves in design applications

Dokhkan, A., Jordan Petroleum Refinery Co.

Crude oil stocks are usually evaluated by true boiling point curves (TBP). Although TBP curves are considered to be good representations of crude stocks properties, they are insufficient for design purposes. Instead, equilibrium flash vaporization (EFV) curves are used. EFV distillation provides better results because it simulates the operation of a true distillation column. In this method, the equilibrium is established between the vapor and liquid phases of the crude oil throughout the distillation process. However, this procedure is tedious. Consequently, EFV distillations are not usually done experimentally for crude-oil stocks. Instead, correlations are used to derive EFV curves from
