Steady‐State Reactive Distillation Simulation Using the Naphtali‐Sandholm Method

Abstract: On a étudié la simulation en régime permanent des colonnes de distillation réactive à l'aide de la méthode de Naphtali-Sandholm (NS) classique. Les résultats pour les colonnes d'acétate de méthyle et de MTBE montrent que la méthode résout effi cacement les équations MEH hautement non linéaires. Dans le système MTBE, trois régimes permanents distincts sont obtenus alors que le facteur d'étapes de Newton diminue, passant de valeurs élevées à des valeurs faibles. On démontre également la polyvalence de cette méth… Show more

“…For systematic tuning of the temperature/composition loops, the ultimate gain (K u ) and ultimate period (P u ) for each of the loops are obtained using the ATV auto-tuning procedure (Astrom and Hagglund, 1984). The standard Tyreus-Luyben controller settings (Singh et al, 2007) detuned by an empirical factor f is used to set the controller gain as K c = K u /(3.2 * f ) and the reset time as I = f * 2.2 * P u . Note that the composition loops are tuned after the temperature loops have been tuned and are on automatic.…”

“…The column is designed for 95 % conversion and 95 mol % purity of the distillate and bottoms products. The column is simulated using our in-house Naphtali-Sandholm method based simulator coded in Matlab [48]. The physical and chemical parameters used to model the system are given in Tab.…”

“…The reboiler duty (= V S × λ ) and the exothermic reaction heat at the base case are 0.8373 and 0.4157 MW respectively. The steady‐state characteristics of the column design are explored using the Napthali‐Sandholm method based steady state simulator . The dynamics are simulated using an algorithm for RD dynamic simulation proposed by Jhon and Lee…”
