How to simultaneously regress the binary interaction parameters involved in the mixing rules and activity coefficients
Thread Content
Ask the experts for advice: How to simultaneously regress the binary interaction parameters involved in the mixing rules and activity coefficients. For example, when calculating fugacity using the SRK equation, the binary interaction parameter Kij in the mixing rule needs to be used, and when calculating the fugacity using the Wilson equation, aij needs to be used. Can these two binary interaction parameters be regressed simultaneously?
I have done work in this area before, because in this case, the SRK equation must be used to calculate the fugacity of the gas phase, and the Wilson equation is used to calculate the activity coefficient of the liquid phase. In the activity coefficient model, aij has a great influence on the equation, and Kij is only fine-tuned in the mixing rule of the state equation.
Good stuff, I hope I can get further guidance.
