Abstract

A new version of Patel and Teja's equation of state is presented, with applications to vapor-liquid equilibrium of mixtures containing polar fluids. The equation requires T_c, P_c and Z_c as input parameters and contains one temperature dependent function and four generalized parameters (in terms of Z_c). Many systems containing hydrocarbons, hydrogen, hydrogen sulfide, etc. have been treated, finding excellent results. Regression analysis to estimate binary interaction parameters has been done by using an improved version of the "fugacity criterion" of Pauvonic et al. Also comparison with several other cubic equations of state has been done. In all cases the proposed equation works better.
