After the first guess and the solution of the matrix equations, the temperature must be corrected. This is done with bubble-point calculations on each stage.
Now the component flow rates are used to determine liquid mole fractions.
This procedure normalizes the mole fractions on each stage so that they sum to 1.0. Once the mole fractions have been determined, the new temperatures on each stage are calculated with bubble-point calculations (Section 5.4), which are illustrated in Example 6-1. To prevent excessive oscillation of temperatures the change in temperature can be damped,
where df is a damping ...
