2. Evaluation of chemical and mechanical resistance of virgin and recycled poly (ethylene terephthalate) and poly(methylene oxide) when applied as gravel pack in petroleum wells
AbstractNowadays more and more unexpected uses for common materials have been observed, especially when recycled polymers are concerned. In this work, the viability for application of virgin and recycled poly(ethylene terephthalate) (PETvir and PETrec, respectively) and also poly(methylene oxide) (PMO) as granular materials (gravel) for gravel packing in san

4. Hydrodynamics and oxygen mass transfer characteristics of petroleum based micro-emulsions in a packed bed split-cylinder airlift reactor
The effects of aeration velocity and liquid properties on the pertinent hydrodynamic and mass transfer parameters in a split-cylinder airlift reactor (with and without packing) were examined. Four different oil-in-water micro-emulsion systems containing kerosene, heavy naphtha, light naphtha and diesel as the oil at the concentration of 7% (v/v) were used in

5. Blendas e filmes de quitosana/amido de milho: estudo da influência da adição de polióis, oxidação do amido e razão amilose/amilopectina nas suas propriedades / Chitosan/corn starch blends and films. Influence of polyol addition, starch oxidation and amylose/amylopectin ratio in their properties
Chitosan/starch association represents an interesting alternative to the preparation of biocompatible drug delivery systems, packing materials and edible films. Changes in rheological, thermal and mechanical properties, water vapor permeability and solubility of chitosan/starch films were evaluated varying the starch structure form (gelatinized or oxidized),

6. NUMERICAL ANALYSIS OF SAND CONTROL METHODS IN OIL-PRODUCING ROCKS / ANÁLISE NUMÉRICA DE MEDIDAS DE CONTENÇÃO DE SÓLIDOS EM ROCHAS PRODUTORAS DE ÓLEO DO BRASIL
During the production steps of a petroleum well, issues regarding sand production may have hight costs due to damages in the equipment or reduction of the well¿s productivity. Such problems make the application of sand control systems in the completion phase one of the most complex and essential parts in the construction of the well. This work aims to simul

8. Flooding characteristics in pulsed packed extraction columns
Flooding behavior of a 76.2 mm diameter pulsed packed column has been determined using four different liquid-liquid systems. The effects of pulsation intensity, flow ratio, interfacial tension, and packing geometry on flood point have been investigated. The results showed that the maximum throughput of the column decreases with an increase in pulsation inten

11. Chilled packing systems for fruit flies (Diptera: Tephritidae) in the sterile insect technique
We evaluated three packing systems (PARC boxes, "GT" screen towers and "MX" screen towers) for the emergence and sexual maturation of sterile fruit flies, at three adult fly densities (1, 1.2 and 1.3 fly/cm²) and three food types. At the lowest density, results showed no significant differences in the longevity and flight ability of adult Anastrepha ludens
