PFIT is used for the creation and maintenance of Binary Interaction Parameter (BIP) databanks within the PPDS Thermodynamic Properties Suite.
It is used to regress phase-equilibrium experimental data to obtain BIPs for industry-standard thermodynamic models such as Peng-Robinson, Wilson and NRTL. It is used in conjunction with the PPDS pure component and model parameter databanks and thus provides a fully quality-assured route to the fitted parameters.
