1. HETP evaluation of structured packing distillation column
Several tests with a hydrocarbon mixture of known composition (C8-C14), obtained from DETEN Chemistry S.A., have been performed in a laboratory distillation column, having 40mm of nominal diameter and 2.2m high, with internals of Sulzer DX gauze stainless steel structured packing. The main purpose of this work was to evaluate HETP of a structured packing lab

2. Experimental vapor-liquid equilibria data for binary mixtures of xylene isomers
Separation of aromatic C8 compounds by distillation is a difficult task due to the low relative volatilities of the compounds and to the high degree of purity required of the final commercial products. For rigorous simulation and optimization of this separation, the use of a model capable of describing vapor-liquid equilibria accurately is necessary. Neverth

3. Separation process of complex mistures / Projeto de processos de separação de sistemas complexos
The separation process of homogeneous and non ideal mixtures is a common problem in chemical industries. The complex mixture separations may happen at low pressure to prevent thermal degradation or using reactive distillation to eliminate existing azeotropes and/or in order to increase the rei ative volatility of the components to be separated. Reactive dist

4. Recuperação de solvente em miscelas oleo de soja/hexano utilizando tecnologia de membranas. / Soja/hexano solvent oil recovery in miscelas using technology of membranes.
Soybean oil is industrially obtained by hexane extraction, producing an oil/hexane miscella that is submitted to distillation for solvent recovery. The process with membranes present low energy consumption and have been proposed to replace or complete the traditional operations in removal of solvent. Furthermore, the use of this technology might result in co

5. Separação adsortiva de misturas etanol-água por processo PSA.
The ethanol is one of the most well-known and diffused fuels sources in nowadays, therefore the domain of its technology has a great importance to the producer countries. Beyond it is in general, lesser expensive than the major part of the petrochemical fuels, the ethanol has its origin in the renewable sources that becomes Brazil in a world power on its pro

6. Avaliação do processo de destilação molecular para obtenção de produtos de alto valor agregado
In the current days, great importance is being given to products that come from natural sources, belonging to the class of products of fine chemistry, which are products of high added value and obtained with high technology. These products are vitamins, substances for the production of cosmetics, pharmaceutical products, coloring products, among others. Quit

7. Modelagem e simulação interativa de colunas de pratos para absorção de gases : um metodo para minimização de poluentes industriais
The objectives of this work are the modeling and the simulation of a plate, multicomponent absorption column, considering the main phenomena taking place in the process and the rigorous thermodynamic of phase equilibria. The problem is considered in the steady-state and adiabatically. A method initially developed for distillation columns is now applied for a

8. Recuperação de energia na destilação do sistema etanol-agua
Energy recovery is now days one the most important tasks that chemical engineeries face, specially when distillation is involved. Between the energy recovery techniques to be applied to distillation columns, vapour recompression has been pointed out as one of the most promissing. The application of this technique has been discussed in the literature and reco
