Reliability of HYSYS crude blending and...

[vak]

Hi everyone
I'm working on a CDU simulation which has a feed composed of seven different crudes. I have entered all crude assay data into HYSYS and made a blend using HYSYS oil manager. My question is: How reliable is HYSYS blending procedure and calculated TBP curve, density, etc. of blended stream?
After blending these crudes, I tried to estimate approximate expected product flows and compare it to an available basic design package. However, I have encountered huge difference between these two values.
Please kindly guide me if simulation softwares are good enough for estimation or if there is any special software created for this purpose

Thanks in advance

Hysis is probably the best. Pl recheck input

hi, dear vak, I think that the stimation of the hysys's distillation procedement depend about how you configured the pseudocomponents that are use to represent the oil. Chek that How are the distribution of the pseudocomponent and which kind of method are you used......
Best regards
