Questions about the model

I would like to ask about the equation of state models PR and SRK used for the simulation of low-carbon hydrocarbon separation – what are their respective advantages and disadvantages, and which one is more suitable? Thank you

The results for light hydrocarbons calculated in proii for these two are similar. Because they are all derivative methods of the equation of state, distinguished only by different values of alpha. After looking at the information on proii, SRK seems not very suitable for non-polar substances and systems containing hydrogen. It has not been used in Aspen+.
