Abstract: Reactive distillation processes are very promising in substituting Sconventional liquid phase reaction processes. However this technology is not suitable for all kind of processes or types of reaction. Therefore, assessing the feasibility of these process concepts forms an important area in current and future research and development activities. The present paper focuses on the feasibility studies based on the construction of residue curve maps for the toluene methylation system. The RCMs were constructed and analyzed; it is concluded that the process of synthesis of xylenes when carried out in the reactive distillation column enhances the selectivity of the desired para isomer.

Residue curve maps are an effective way of representing phase equilibria in non-ideal multicomponent mixtures. In this representation the phase equilibrium surfaces are replaced by an equivalent flow of trajectories of a vector field. The flow is characterized by a set of singular points that correspond to the pure components and azeotropes present in the mixture. It is shown that the patterns in these maps for reaction mixtures obey a global constraint arising from a topological invariant for the manifold on which they are defined. This constraint is in the form of an integer equation that phase diagrams must obey in addition to the Gibbs phase rule. The main advantage of the method is that certain global statements can be made about the structure of reactive phase diagrams, independently of the details of phase equilibrium data or models.
