The MKS-EOS with new mixing rules: the MKS/1 model

The MKS-EOS proposed by Chu et al. (1992) has been further improved in order to apply it to near-critical, polar, and highly asymmetric gas condensate mixtures. The Kurihara density-independent local-composition mixing rule for the energy parameter a has been included (Kurihara et al., 1987), and test results for selected high quality VLE data indicate that a net improvement is obtained for polar mixtures.
