In all cases, I think you arrived at about the same results which were obtained by Chemcad, the % vapor you got is much higher (much much higher) than the actual EFV curve results.

I think you should try the heater outlet conditions at pressure = 30 psia, it will give you slightly lower % vaporized, as the 25 psia is at flash zone and in this case you can't compare your results to the manual results obtained by Watkins since he used stripping steam which will give more vaporization than dry conditions.
Also, several people have written me to the email requesting an example.

Thanks, it seems you took a practial step, which software did you use ? Therefore, the connection between chemical process simulation programs (Aspen Plus, Hysys, Pro II, etc.) and tools such as Matlab are very useful. If you are struggling with your process plant simulation finding a way to simulate your thesis work on aspen tech (hysys and plus) i am Fahad Uzair having 9 plus working year of experience in diverse fields of oil and gas industry and certified from aspen tech. Since my only available option is Chemcad, I was informed it doesn't provide EFV curve, but the % vaporized calculated by it should be close to what Watkins calculated since he used the only known method for creating EFV, otherwise the built in method in Chemcad for crude phase change won't be accurate enough. hey there One solution for all your problems. Aspen Tutorial 2 13 As mentioned above, Aspen can give correct but unreasonable results due to convergence or the selected thermodynamics, so it is highly recommended that you verify the results presented in this table. It allows using industry-specific unit operation models and powerful tools to optimize operating parameters for feedstock changes. I presume that the simulators do not have other ways to create the EFV. Developer: AspenTech On the market: commercial Main Features: Aspen HYSYS, similar to Aspen Plus but dedicated to process simulation of oil, gas and refining processes. Creating EFV is a manual method, but it is the only known method (as far as I know).
There have been few simulating software packages such as Aspen Plus, Aspen HYSYS and PRO/II for use in the oil and gas industries. I.e Cant specify temperature on a product stream and the program back calculates. My knowledge so far concerning crude distillation is that using the TBP curve to construct the EFV curve of the whole crude at heater outlet conditions and flash zone is the first step for successful distillation calculations, because it will give the actual % vaporized. Process simulation software packages are extensively used nowadays to estimate the product efficiency and enhance the performance of the system by optimizing operating parameters 12. Aspen programs solve via having correct number of known variables where PROII is solving linearly from start to finish.
