Peng Robinson BIPs Estimation Method In Hysys

Peng Robinson BIPs Estimation Method In Hysys

(OP)
Dear All,
Whenever I am selecting the Peng-Robinson fluid package in Hysys, I find estimated values of Binary Interaction Parameters (BIPs) that are used for the calculation. Anyone have an idea by what method those BIPs are estimated ? is it Group Contribution method? or another method? or they are determined experimentally?
