Methods for obtaining binary interaction parameters lacking experimental data

2012-05-16View Original

Thread Content

As the title suggests, in Aspen Plus, when there are three components A, B, and C, and experimental data on gas-liquid equilibrium are available for the pairs A&B and A&C, but no such data exist for B&C, we can use the existing experimental data for these two pairs to perform regression and thereby obtain the binary interaction parameters between any two of the components A, B, and C. I remember it being called something like transitivity, so I’m wondering if any of you experts know its exact name as well as the basic principle behind it? Thank you!
