Estudo de otimização geométrica de pás de um reator CSTR em seu processo de agitação mecânica da mistura reacional

Abstract

Chemical reactors resorted to continuous stirred tanks, also CSTRs as chemical development industry that should be considered a value-added process. The CSTR is supplied by a vial of physical substance that is inserted or more reactive under agitation. Such agitation is performed by a stirrer or fluid mixer within the tank in order to provide greater translocation of the reactants into products by providing increased interactivity between the reaction fluids, thereby increasing the efficiency of the final conversion. In the market for types of mixers that use dimensional geometry systems. Each reaction geometry is associated with the physical-chemical properties of the reaction medium that is exposed. The present work is an optimization of the geometry of the type of insulation with transversal slope obtained along a geometry that is a process of reaction with greater efficiency same mixing power of the mechanical agitator. The study consisted in performing a parametric selection of a standard geometry obtained by the means of computational simulation techniques. Using as computational fluid dynamics theories, it was possible to perform an analysis and comparison between generated geometries as a variation of the homogenization of the two fluids temperature, besides the efficiency of the mixture with reference to the mixture with the agitator: in a first analysis with 25 geometries generated via parametric comparison, of which 3 with higher correlation performance was evaluated through the final acid-base analysis. The version used was sulfonic acid and sodium hydroxide, forming sodium sulfide and water. The best geometric configuration of the impulses and torsions 80 and 60º.
