Abstract
This work is motivated by the current obstacles hindering the implementation of reactive distillation in industry, mainly related to the complexities of its design and control, as well as the impact of uncertainties thereupon. A framework to systematically investigate the impact of uncertainty on reactive distillation processes is presented, considering the relevant control system and potential redesign of the column, possibly including additional ancillary equipment, with the aim to make the process more robust and to mitigate risk. The framework also considers the impact of operational uncertainties, showing that a system which can tolerate design uncertainty may nevertheless still be sensitive to operational uncertainties, in which case the mitigation strategies presented in this work should be applied to enhance system robustness. This framework can be used in an early design stage to quantify the impact of specific input parameters on process performance and costs, and it can therefore be used to steer the experimental work to focus on determining the most critical parameters for a reactive distillation process. Three case studies are considered showing that, for reactive distillation, uncertainty in the rate constant has a more significant impact on the system performance than a similar uncertainty in chemical equilibrium.
