This paper presents a simulation algorithm for a distillation column with simplified heat and mass transfer models. The proposed simplified model neglects the liquid phase film resistance, thus reduces the number of variables and basic equations to about 2/3 and makes the algorithm more straightforward compared with the rigorous model. Simulation results are compared under different operating conditions. They show that (1) the simplified model can give simulation results close to those obtained by the rigorous model, and (2) it is numerically stable and yields the results with less calculation time.
