- Abstract: In this work, an industrial hydrogenation reactor from a multinational chemical company, located at São Paulo state in Brazil, was mathematically modeled and then simulated at MATLAB. The model, based on the kinetic reactions, and mass and energy balances, was validated through real plant data and then, the open-loop dynamic of the process was evaluated through a sensitivity analysis. Considering the results of the sensitivity analysis, three new temperature control strategies were proposed: cascade, override and cascade+override. These techniques were then compared with each other and with the current feedback controller of the industrial hydrogenation reactor. As a result, the cascade controller showed good results regarding not only temperature tracking, but also for product quality, and then was chosen as the most suitable for this case study. In addition, several future work proposals were done, aiming the use of tools to refine the model, use of the model to perform operational training and process safety analysis, development and comparison with other control strategies, and investigation of anti-reset windup and controller tuning methodologies.
