Abstract
The Fixed-Bed Three-Phase Reactors (FBTRs) are used equipment in the petrochemical and petroleum industries with diverse applications. Effective control of these reactors is critical to secure operations, especially when high performance is desired. In this way, the reactor must be controlled very well and for that, a mathematical model is needed that describe its behavior in the best possible way, being able even to predict its dynamic behavior. In this sense, the present work aims to perform the mathematical modeling of FBTR. To perform the modeling the technique known how coupled integral equation approach was applied to the energy balance equations of the fluid and solid phases, transforming the Partial Differential Equations (PDEs) into Ordinary Differential Equations (ODEs). The results of the work were obtained through the elaboration of software in the language FORTRAN 95, where the Euler method was applied in the ODEs obtaining the graphs for the temperature versus time. In this way, it can be concluded that in this present model the heat transfer coefficient is important for the control of the reactor, being sensitive to changes and that to obtain the time of stabilization of the temperature of the reactor obtaining a control of this reactor and avoiding the formation of hot spots.
