RESUMO

Mixing is a unit operation with applicability in many industrial fields, such as food, chemical, petrochemical, beverages and pharmaceutical, just to say some fields. The static mixers appear with an alternative to the traditional agitated vessels. They could be used such in batch mixing operation as in continuous processes, but mainly in continuous processes. The Brazilian suppliers had some problems in choosing the adequate equipment, and it is not rare that they choose an equipment that really does the proper mixture, but with a very high consumption of energy. The recently concern about saving energy demands a special care about the choosing of the best static mixer for the particular task.It was selected two models (ALETAS and EDA) from another work that developed static mixers using computational fluid-dynamic (CFD) method, the ALETAS mixer for laminar mixing and EDA for turbulent mixing. This work searches to complete this study, by experimental tests in laminar and turbulent mixing conditions.The results show that ALETAS static mixer can be used in laminar mixing, as the EDA static mixer but the EDA can be used in laminar mixing with some particular cares. The EDA can also be used in the turbulent mixing. Both models of static mixers were also compared with the Kenics and Sulzer SMX commercial static mixers using the data available in the literature with very similar results
