Parameters

Vx  Array
Vector of doubles containing vapor phase molar composition for each component in the mixture.
T  Double
Temperature in K
Pref  Double  (Optional)
Initial estimate for Pressure, in Pa
K  Array  (Optional)
Vector with initial estimates for K-values
ReuseK  Boolean  (Optional)
Boolean indicating wether to use the initial estimates for K-values or not.

Return Value

Object
Returns the object vector {L, V, Vx, Vy, P, ecount, Ki} where L is the liquid phase molar fraction, V is the vapor phase molar fraction, Vx is the liquid phase molar composition vector, Vy is the vapor phase molar composition vector, P is the calculated Pressure in Pa, ecount is the number of iterations and Ki is a vector containing the calculated K-values.
Remarks
The composition vector must follow the same sequence as the components which were added in the material stream.
