Vapor-liquid equilibria by the pseudocritical method
The New Jersey Institute of Technology has extended the pseudocritical method of B.I.Lee and M.G. Kesler to the calculation of component fugacity coefficients and vapor-liquid equilibria. The Lee-Kesler mixing rules have been modified by the introduction of binary interaction constants, which are evaluated from experimental pseudocritical constants. The critical compressibility factor is introduced as a correlating fourth parameter. The resulting component fugacity coefficients agree with experimental values and with experimentally determined vapor-liquid equilibrium ratios. The proposed method may be applied to systems with any number of components. It is well-adapted to computer programming, being based on the modified BWR equation of Lee and Kesler. Components presented are methane, propane, n-butane, and carbon dioxide.
