HYSYS simulation of gasoline vapor pressure
Thread Content
The actual vapor pressure is 62, while the software calculates it to be 90. What should be done?
It might be due to different definitions of the components, or the chosen methods for determining physical properties are not suitable; you can check whether the physical properties of the simulated gasoline match those in reality. P.S. I’m also a newbie; I’d like to share my thoughts.
It’s the same even if the physical properties change; the composition is simply determined by entering d86 and density
Are the light components and virtual components not defined?
You can take a look at the specific steps for oil characterization; I don’t remember them very well either, as I haven’t used it in a long time.
Both d86 and true boiling point distillation are experimental methods used to predict the properties of oils.
