SUMMARY – Processium, a French company newly implemented in Brazil, is an expert in industrial process engineering. We design, develop and improve processes for chemical, petrochemical and biotech industries. CAPEX and OPEX are key criteria to effectively operate a process. Reactive distillation is a process intensification technology particularly suitable to reduce these costs. We present a design study of an ester hydrolysis process in which different reactive distillation configuration are compared. The process specification on low residual ester content implies a very high rate of conversion. Reactive distillation achieves this goal without recycling and consequently allows the utilization of compact equipments. Thermodynamic and kinetic data are measured and modeled to develop reliable process simulation models. After process optimization, the economic optimum is determined for each process. The next step is experimental validation in a pilot-scale reactive distillation column.
