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. Cristalização de insulina suina com dioxido de carbono como agente acidificante / Crystallization of porcine insulin with carbon dioxide as acidifying agent
Crystallization is a separation and purification technique used in the production of chemical, pharmaceutical and food products. The majority of the solid products is obtained by crystallization/precipitation processes that probably are the second most important separation technology in terms of capacity, behind only distillation processes. Studies on the us

3. Avaliação do efeito do sal volatil carbamato de amonio sobre a estabilidade de enzimas / Evaluation of the effect of ammonium carbamate on the stability of enzymes
Salting-out is a precipitation method frequently found in downstream processing schemes of proteins. However, the need for post-precipitation treatment for salt recovery and final purification of the protein may lead precipitation with conventional salts to be costly and limited for environmental questions. Precipitation with Volatile salts is an alternative

4. Study of the isoelectric precipitation of porcine insulin in aqueous solutions with carbon dioxide / Estudo da precipitação isoeletrica da insulina suina em soluções aquosas com o dioxido de carbono
Precipitation is a technique frequently employed in downstream process for the recovery of proteins from aqueous solutions. One example of such technique is the isoelectric precipitation, which consists of the adjustment of solution pH to the value where the protein has zero net charge, the isoelectric point, pI. Commonly, mineral acids and bases are used fo
