For ternary systems, the use of residue curve maps as a representation of the phase behavior has greatly facilitated process synthesis. Especially important is the knowledge of distillation boundaries, which cannot be crossed by simple distillation. Here, an attempt is made to extend these procedures to quaternary systems by presenting a method to...

The objective of this paper is to illustrate process design from the industrial point of view for a heterogeneous reactive distillation exemplified by the decomposition of MTBE. Based on thermodynamics a plausible column concept is suggested. Open questions concerning scale-up of structured catalytic packings are discussed on the basis of experimen...

Isothermal vapor–liquid equilibrium (VLE) and excess enthalpy (HE) data were measured for binary systems required for the design of reactive distillation processes for the methyl acetate production. The isothermal P–x data were measured with the help of a computer-operated static apparatus. A commercial isothermal flow calorimeter was used for the...

Reactive distillation experiments have been performed for the synthesis and hydrolysis of methyl acetate using the structured catalytic packing Katapak-S with an acidic ion-exchange resin (Amberlyst 15) as the heterogeneous catalyst. Three different setups were used:  one-feed and two-feed setups for the methyl acetate synthesis and another two-fee...

The reaction kinetics and chemical equilibrium of the reversible esterification of methanol with acetic acid were investigated. This system is of major importance as a model reaction for reactive distillation. The reaction has been catalyzed both homogeneously by acetic acid itself and heterogeneously by an acidic ion-exchange resin (Amberlyst 15)....

The design of reactive distillation processes requires besides the knowledge of phase equilibrium data reliable kinetic data. This paper presents the results of kinetic measurements of acetic acid esterification with methanol together with results for the backward reaction, the hydrolysis of methyl acetate, both catalyzed by the macroreticular, str...
