Vapor-liquid equilibria from an improved hard convex body expansion method. Part II. Non-polar mixtures. Fluid Phase Equilibria, 86: 87-109. This study presents an improved vapor-liquid equilibrium calculation method for non-polar mixtures by employing the hard convex body expansion (HCBE) theory. The repulsive contribution to thermodynamic properties is determined at a given density, where the pseudo-volume parameter is calculated by a modified one-fluid theory. A generalized corresponding states equation with two reference fluids is used to calculate the attractive contribution. A combined model applying the van der Waals one-fluid (VDW-1) and the mean density approximation (MDA) theories has been used to determine the pseudo-energy parameter for the attractive property calculations. This work is an extension of our previous studies on non-polar pure fluids in which we have correlated the geometrical acentric factors. The calculation results are very satisfactory and are better than those obtained by applying only the VDW-1 or MDA method for the attractive property computations. Henry's constants of light hydrocarbons in heavy alkanes can also be predicted successfully by the method of this work. ? 1993.journal article10.1016/0378-3812(93)87170-62-s2.0-0027629625https://www.scopus.com/inward/record.uri?eid=2-s2.0-0027629625&doi=10.1016%2f0378-3812%2893%2987170-6&partnerID=40&md5=40c99ce3d743fb27c0b26db494853b7a
