Abstract

Wagner constants are estimated from VLE predictions
based solely on the critical and normal boiling points, and acentric factor.  The predictions come from the
standard forms of 1) Riedel and 2) Ambrose-Walton, 3) a modified
Riedel equation resulting from forcing the value of K to provide zero error at
the reduced temperature of 0.7, and 4) a modified Ambrose-Walton equation
resulting from using a pseudo acentric factor that provides zero error at the
normal boiling point.  Reduced vapor
pressure values obtained using these Wagner constants are compared to those
generated by using literature-reported Wagner constants that are applicable for
the entire two-phase VLE curve for 72 species. I
t is shown that the Wagner equation parameterized using VLE predictions
from such correlations can provide better accuracy than the underlying source
correlations themselves, and it can exhibit less error than a parameterization
using a limited interval of experimental data.
