The empirical molecular shape factors for ammonia relative to methane as a reference were correlated for 0.7≤Tr≤, 1.4 and 0<Pr≤30. They could well represent the compressibility factors and the fugacity coefficients of ammonia. On the basis of the corresponding-states principle, the vapor-liquid equilibria of binary systems containing ammonia were predicted by using pseudo-potential parameters, obtained by the van der Waals one-fluid theory coupled with molecular shape factors. Good results were obtained except in high pressure ranges.
