1. Modelagem de equilíbrio líquido-líquido, líquido-vapor e líquido-líquido-vapor para sistemas binários, ternários, quaternários e pseudo-quaternários, envolvendo a produção de biodiesel / Modeling of liquid-liquid, liquid-vapor and liquid-liquid-vapor equilibria for binary, ternary, quarternay and pseudo-quaternary systems involving biodiesel production
The worldwide energy demand increases every year. This demand will reach levels that cannot be supplied by current conventional fossil fuel resources. In this context, biofuels arise as a growing primary source of energy, raising research opportunities and encouraging technology development. An important technical issue related to biofuels development is the

2. Vapor-liquid equilibrium measurements for the binary system methyl acetate+ethanol at 0.3 and 0.7 MPa
This paper reports experimental data of the isobaric vapor-liquid equilibria (VLE) for the mixture methyl acetate + ethanol at 0.3 and 0.7 MPa, determined using a copper still ebulliometer. The activity coefficients obtained from the experimental data were correlated by using different thermodynamic mathematical models. All the binary systems show a positive

3. Simulation of styrene polymerization reactors: kinetic and thermodynamic modeling
A mathematical model for the free radical polymerization of styrene is developed to predict the steady-state and dynamic behavior of a continuous process. Special emphasis is given for the kinetic and thermodynamic models, where the most sensitive parameters were estimated using data from an industrial plant. The thermodynamic model is based on a cubic equat

4. Aspectos numéricos do problema de cálculo de fenômenos de vaporização retrógrada dupla / Numerical aspects of the problem of calculation of phenomenon of double retrograde vaporization
A vaporização retrógrada dupla é um fenômeno termodinâmico onde, ao invés de uma usual curva de ponto de orvalho, o lugar geométrico dos pontos de orvalho apresenta duas abóbadas (ou domos), em temperaturas ligeiramente acima da temperatura crítica do componente mais volátil, e tem uma forma em S, em temperaturas ligeiramente abaixo da referida te

5. Modelo de ordem reduzida de uma coluna de destilação extrativa salina em estado estacionario
One of the major difficulties at mathematical models of staged separation systems is the large dimensionlity of the process models. These models introduce significant computational effort especially in cases involving repetitive simulations such as optimization and dynamic simulation for control systems The need of the efficient process models which require
