6. Equilibrium Properties¶
The equilibrium behavior for each component \(i\) are specified using the following \(K\)-value relationships
\[y_i = K_i(T,p)x_i\]
where \(y_i\) is the vapor phase mole fraction and \(x_i\) is the liquid phase mole fraction. Here, we have assumed for simplicity that \(K_i\) does not depend on composition.
In order to calculate the enthalpies of the liquid and vapor streams, heat capacities and heats of vaporization are required.
The heats of vaporization and heat capacities of the liquid are obtained from [Perry]. The equilibrium properties are taken from the DePriester charts in [Wankat]. The heat capacities of the vapor are currently estimated as a polyatomic ideal gas.
