Abstract
Polymer reactors are one of the most remarkable models of batch reactors, which are widely revealed in the petrochemical industry due to its crucial and omnipresent role. The heat transfer in a polymer reactor is essential because it is concerned with the precise control of the polymerization process. In this thesis, the heat transfer in polymer reactors has been investigated. The study of the methods of heat transfer in jacketed agitated vessels, and the impact of altering different agitators on the heat transfer, are indicated. A computer program is developed to calculate the heat transfer parameters and the heat duty required for each case. The PVC polymer reactor in the Egyptian Petrochemical Company is chosen as a case study. This reactor is modeled by Microsoft Excel and simulated by a VisiMix simulation program version turbulent SV. In addition, the chemical reaction is modeled by Aspen HYSYS V8, and eventually the modeling results are validated with the actual design data. Meanwhile, a comparison between various heat transfer methods is generated to set the most preferable design and the topmost efficient impeller for high heat transfer conditions. Furthermore, this preferred design is adopted to analyze the alteration on its performance. The result indicates that, a retreating turbine impeller is the best for a high inside heat transfer coefficient and a half-coil jacket is the best for a maximum outside heat transfer coefficient. The performance investigation shows that this design is the most preferable for the optimum recommended flow velocity in the jacket of v=2.3m/s, as the outside heat transfer coefficient would increase by 31.47%. Finally, the new approach, which is released by Vinnolit Uhde Company, is applied and its result shows that the heat duty would increase by 32% due to the installation of an inner cooler inside the reactor wall, which represents a significant stride for a high performance polymer reactor.
