Modified Redlich—Kwong equation of state for saturated vapour—liquid equilibrium

Defining the dimensionless temperature T* as: T* = ( T c T −1)/( T c T NB −1) a new temperature dependence of the attractive force part of the Redlich—Kwong equation of state is presented. The new modified Redlich—Kwong equation predicts the saturated liquid—vapour equilibrium states accurately over...

Description
Summary:Defining the dimensionless temperature T* as: T* = ( T c T −1)/( T c T NB −1) a new temperature dependence of the attractive force part of the Redlich—Kwong equation of state is presented. The new modified Redlich—Kwong equation predicts the saturated liquid—vapour equilibrium states accurately over the entire liquid range from the triple point up to the critical point. A comparison is made with experimental data for a series of selected organic, inorganic and quantal fluids (34 compounds, 740 data points pairs) and results obtaine by the use of two modifications by Soave of the Redlich—Kwong equation of state.
