Abstract

A recent study introduced a new class of control structures using one-point temperature control applicable to heterogeneous reactive distillation. The feed rate of one reactant sets the plant capacity. The inventory of the other reactant is inferred from measuring the reflux rate or reflux ratio and is managed by adjusting the second feed flow. This idea can be implemented in different ways. Here, the applicability of these structures to various esterification systems of industrial importance is assessed. The analysis is based on key thermodynamic data: boiling points, azeotropy and liquid-liquid equilibria. As a rule-of-thumb, if water is the lightest and the ester the heaviest boiler in the system, and if at least the alcohol forms a minimum boiling heterogeneous azeotrope with water, then the new class of control structures may be applicable.
