文摘

A new non-iterative fugacity-activity thermodynamic model is proposed. The model aims to predict the solubility of gas mixtures gas mixtures in brine. The proposed model is solved using PR EOS and PPR78 EOS to calculate φi. Best predictions of gas mixtures solubility are obtained using PR EOS. Its accuracy is practically the same to that of iterative models.
