1. Análise da influência de impelidores laterais no tempo de mistura em tanques de estocagem de diesel com o uso da fluidodinâmica computacional / Analysis of the influence of side-entry mixers on the mixing time in diesel storage vessels using computational fluid dynamics
The homogenization process of hydrocarbons in large scale storage tanks equipped with side-entry impellers plays an important role in a refinery operation, since the quality of the final products depends on the performance of this process. Computational Fluid Dynamics (CFD) is the most viable technique to evaluate and to optimize this process, as experimenta

2. Desenvolvimento de processo contínuo de copolimerização em emulsão em reator tubular. / Development of a continuous emulsion copolymerization process in a tubular reactor.
Industrial emulsion polymerization processes are usually performed in batch or semi-batch stirred tanks, or in continuous stirred tank reactors (CSTR). Continuous reactors have the advantage of being smaller and providing a better product quality control by the reduction of the batch-to-batch variations. In addition, periodical self-sustained oscillations in

3. AnÃlise dinÃmica de um forno rotativo piloto contÃnuo para produÃÃo de gesso beta com GLP
Direct contact rotary kilns are widely used equipments with many industrial applications. The evaluation of the residence-time of the particles on these reactors is fundamental in the development of controlled and optimized systems. In the present work, a technique to measure the residence-time distribution (RTD) was developed in a rotary kiln of 5,45m long

4. Analise critica das correlações e parametros fundamentais em sistemas de agitação
O projeto atual de agitadores químicos é essencialmente dependente de relações empíricas, visto que as leis fisicas que regem os fenômenos envolvidos nos processos químicos são expressões cuja solução analítica é ainda desconhecida. Devido a isto, trabalhos experimentais como os compilados por Nagata, (1975), Oldshue, (1983), Sano e Usui, (1985)

5. Modelos matematicos para reator de lama trifasico aplicados a hidrogenação do o-cresol
ln this work is presenteel the moeleling anel the simulation for three mathematical models for three-phase catalytic reactor. The models are steadly-state and one-diimensional. The mathematical formulation of the models is shown, by the consieleration of the mass and energy balances. ln the first model the reactor is considered a series of perfectly mixing t

6. Sampling Culturable Heterotrophs from Microcosms: a Statistical Analysis
The contributions of different sources of error in sampling mixed and unmixed bacterial microcosms were evaluated by using analysis of variance. Culturable heterotrophic bacteria from a turbid freshwater impoundment were sampled from 9-liter tanks that were unagitated or mixed with magnetic stirrers or pumps and from dilution bottles that were unagitated or

7. Klebsielleae in drinking water emanating from redwood tanks.
A survey was made of the bacteriological quality and chlorine content of 33 public and private water systems that utilize redwood storage tanks. Coliforms of the genera Klebsiella and Enterobacter were isolated from 9 of 10 private drinking water systems and from 11 of 23 water systems in state and federal parks. Total coliform counts in the private systems
