Title in Portuguese
Avaliação de um novo modelo de reator de cavitação hidrodinâmica para o aquecimento controlado de líquidos e produção de emulsões em escala sub-micrométrica.
Keywords in Portuguese
Aquecimento de líquidos
Cavitação
Emulsificação
Homogeneizador de alta velocidade
Abstract in Portuguese
O presente trabalho consiste na avaliação de um novo modelo de reator de cavitação hidrodinâmica pertencente à classe dos homogeneizadores de alta velocidade, comercialmente conhecidos por High Speed Homogeneizers. É sabido que esse tipo de equipamento possui um amplo leque de aplicações industriais, sendo muitas vezes constituintes de operações unitárias para emulsificação, homogeneização, síntese química, dentre outras. Neste trabalho fez-se um estudo da eficiência deste novo modelo para duas aplicações, o aquecimento controlado de líquidos e a produção de emulsões de óleo em água com diâmetros de partículas em escala sub-micrométricas. As duas aplicações foram estudadas em uma planta piloto, de onde foi possível constatar o potencial de aplicação desse novo modelo de reator, especialmente devido ao baixo custo operacional e praticidade de operação.

Abstract in English
This work evaluates a new model of hydrodynamic cavitation reactor, which belongs to the class of high-speed homogenizers. This type of equipment has a wide range of industrial applications and it is often constituent of unit operations for emulsification, homogenization, chemical synthesis, among others. In this master thesis a study regarding the efficiency of this new model for two applications was made: the controlled heating of fluid and the production of oil in water emulsions with particle diameters in the sub-micrometer scale. The two applications were studied in a pilot plant, where it was possible to see the potential of applying this new model of reactor, especially due to the low operating costs and practicality of operation.
