Reactive distillation (RD) represents a complex process. The multicomponent nature of processed mixtures and also coexistence of reaction and separation at the same time, results in a complicated mathematical model. The major part of this equation system is composed of strongly non-linear equations, solving which an iterative technique has to be used. This is true for both of the different depth approaches, which are describing RD column. Namely, equilibrium (EQ) stage model and more complex non-equilibrium (nonEQ). To obtain solution of the most precise model (nonEQ) following strategy can be applied. The steady state solution from EQ model can be used as a first trial to initialize computation of nonEQ model. Nevertheless, the problem still remains in estimation of initial values for EQ model.
To fill this gap, in following work there will be introduced and explained algorithm, which will estimate preliminary parameters of reactive distillation device. The aim is that the results from this program could be used as first trial values for EQ model and consequently for more rigorous nonEQ model.
