1. CFD modeling of two immiscible fluids mixing in a commercial scale static mixer
A Computational Fluid Dynamics model based on the Eulerian formulation for multiphase flow was developed to model the mixing hydrodynamics of two immiscible fluids in a commercial scale static mixer. The two immiscible liquids were condensate and caustic solutions and were considered as two phases that are interpenetrating each other. The aim of this study w

2. Aproveitamento de membranas de osmose inversa descartadas da indústria para o reuso da purga de torres de resfriamento
Reverse osmosis plants use new membranes to produce demineralized water. After a period of three to five years, the membranes are replaced by news ones due to levels of treatment which are not suitable for production of water with the desired characteristics. This process generates a lot of rejected modules causing an environmental problem. The present work

7. The contributing factors for selecting partners in bilateral non-equity technological alliances in the Brazilian chemical sector / Os fatores condicionantes da seleção de parceiros nos projetos de alianças estratégicas tecnológicas bilaterais sem participação acionária em empresas industriais do setor químico brasileiro
Although the strategic alliances are one of the strategic alternatives known since the 1970s, it was only twenty years later that finally started the rapid growth of this kind of cooperation, its scope and its coexistence with other organizational forms (HARBISO8 and PEKAR, 1998). At the present time, as projects complexity increases and products and service
