| Abstract | |
Polymerization process are important because of their large applications in the world market, for example, rubber, ink, plastic, etc. Appropriate simulation, analysis and control of a floor plan are fundamental for it safety operation and developing, providing the actual competitiveness with high quality production. This work intend to developing a detailed and deterministic mathematical model and elaborating of software using the numerical solution of a equations system obtained by Finite Volumes Method. Study case considered is the ethane polymerization in solution in a tubular reactor with catalysis Ziegler-Natta with and without micromixing. In this study were developed a model that simulates the ethane polymerization process in solution with catalysis Ziegler-Natta in a sequence of reactors PFR (Plug Flow Reactor) and CSTR (Continuous Stirred Tank Reactor), emphasizing the PFR results. The necessary parameters for model quantitative results, like kinetics constants, were calculated with Politeno SA industrial process data. The effect of the most important entrance variables in the reactor performance and in the polymer final properties were evaluated by simulations. The results show convergence for the process without micromixing. (AU) | |
