Abstract

The work analysed the impact of operating conditions and geometric changes in the thermal performance of a esterification industrial reactor of the company M&G. The analyses used a numerical model created with the aid of the software FLUENT. The simplifying hypothesis of considering only one liquid phase instead of the real system three phases was capable of showing the main characteristics of the flow and the heat transfer inside the reactor, like stagnation zones and impellers influence zones, and the heat transfer from the axial coil. The results lead to the conclusion that the agitation system have only a secundary role in the reactor thermal performance, while the role of the flow separation discs is dominant (AU)
