Phase behavior modeling for gas condensate fluids with PC-SAFT and an improved binary interaction coefficient model

The average absolute deviations percent (AAD%) for the dew point pressure prediction over the evaluation samples data, by PR is 20.8, by PC-SAFT with HM BICs, AAD% is 18.0 and for PC-SAFT with the proposed BICs model, AAD% is 9.6. All of these results are taken over the same samples when the EOS are used in prediction mode (after BIC model development). Beside this, the predictions of the liquid dropout are relatively improved in the case of PC-SAFT respect to Peng Robinson with the proposed set of binary interaction coefficients.
