1. Aplicação do método da minimização da energia de Gibbs no cálculo de equilíbrio químico e de fases em sistemas eletrolíticos / Application method of the Gibbs energy minimization to calculation of phase and chemical equilibrium in electrolyte systems
In several industrial applications are used mixtures containing different solutes, often these solutes are non-volatile, such as electrolytes. The phase and chemical equilibrium in these processes occur in the various unit operations. The stages of production, as well as the separation and purification steps are critical to product quality. Thus, the calcula

2. Evaluation of commercial electrolytic solutions administered experimentally by intravenous access in dehydrated dogs by restriction and polyuria / Avaliação de soluções eletrolíticas comerciais administradas por via intravenosa em cães desidratados experimentalmente por restrição e poliúria
Dehydration is one of the most common disorders in the veterinary medicine. Fluid therapy is used to correction of fluid, electrolyte and acid-base disorders. This study was made to compare the effect of three electrolytic solutions administered by intravenous access. Six male adult dogs, weighting 5 and 15 kg were submitted to a dehydration protocol by rest

3. Evaluation of the liquid-liquid extraction process with salt addition for organic acid recovery and purification / Avaliação do processo de extração liquido-liquido com a adição de sais para recuperação e purificação de acidos organicos
This study aims a critical evaluation of the liquid-liquid extraction process of organic acids, produced by fermentation. The organic acids of interest in this work are: citric acid, malic acid, succinic acid and tartaric acid. The study includes the recovery and the purification of the chosen organic acids, the thermodynamic characterization of the systems,

4. Study of sodium chloride scaling in salt dissolver of a chlor-alkali plant / Estudo da incrustação em saturador de cloreto de sódio em unidade de produção de cloro-soda.
In the chlor-alkali industry, a Salt Dissolver has the objective of producing brine saturated in sodium chloride to feed electrolytic cells. However, the Dissolver studied in this work presented an incrustation of 1.5 meters of thickness, formed during nine years of operation. Many samples were collected in distinct positions of the equipment to allow proper

5. Conductimetric determination of thermodynamic pairing constants for symmetrical electrolytes
Earlier theories of electrolytic conductance are reviewed; all of these, with the exception of the Arrhenius-Ostwald theory, are based on physical models. Their theory failed to describe the conductance of strong electrolytes because it did not include the effects (then unsuspected) of long-range forces on mobility. Thermodynamic derivations are independent
