UNIFAC group interaction parameter estimation
« on: July 31, 2019, 12:50:41 PM »
I'm working on modelling the ternary LLE of HMF-water-MIBK with UNIFAC(Dortmund).

The problem is that there is no functional group that can modelled HMF molecule directly. Thus, I'm using FUR-CH3OH. Then, I tried to estimate the group interaction parameter (a,b,c) using to calculate the temperature-dependent term. I would like to ask anyone here who expertise in ASPEN PLUS to guide me how to do the parameter estimation of missing parameter. I have the experiment data of the LLE of the system which can be used for regression.

Thank you in advance.
