其平衡常数的误差均小于8%.各二元对露点的误差均小于1K.

Abstract

On the basis of the Soave and Martin-Hou equations

a new cubic equation of state is suggested. Expressions for calculating its constants and the corresponding formulas for its thermodynamic functions were derived. Good agreement was obtained between literature values and results calculated from phase equilibrium constants and dew points for ten binary pairs.
