Analyse de faisabilité, conception et simulation de la distillation réactive liquide-liquide-vapeur. Application et validation expérimentale sur la production de l'acétate de n-propyle

Abstract : A design methodology of reactive distillation process applied to vapor-liquid-liquid mixtures is presented in this study. Only a few work has been dedicated to such systems whereas they constitute a large application area of reactive distillation; therefore it represents a gap to fill in.
Reliable and consistant computation of chemical and phase equilibria is required beforehand any feasibility assessment, design or simulation.
The two most general ways to find such an equilibrium is to minimize the free Gibbs energy or to solve a specific set of equations; a single set of equations being able to describe all physical states of the system is defined instead of these two traditional approaches, avoiding numerical problems while keeping implementation and resolution simplicity.
A reactive residue curve map (rRCM) tool taking into account chemical and phase equilibria has been developed and checked for C1-C5 acetate esterifications. Finally a feasible design on the high purity n-propyl acetate production, based on the rRCM analysis and publications, has been performed confirmed by steady-state simulation runs; the simulation tool was validated by thermodynamic, kinetic and pilot plant experiments. These experiments are presented detailed in the paper.
