1. ENERGY AND EXERGETIC EVALUATION OF THE MULTICOMPONENT SEPARATION OF PETROCHEMICAL NAPHTHA IN FALLING FILM DISTILLATION COLUMNS
Abstract Multicomponent separation of synthetic petrochemical naphtha (hexane, cyclohexane, toluene and xylene) was carried out in a falling film distillation sequence with heat supply using a vapor chamber (thermosyphon). Tests were carried out by varying feed flow rate and temperatures of the feed and the vapor chamber in two ways of heat supply: isotherma

2. SimulaÃÃo e avaliaÃÃo de um sistema de aquecimento solar de Ãgua utilizando balanÃo energÃtico / Simulation and evaluation of a system of solar water heating using energy balance
This work was developed at the State University of West of Paranà â UNIOESTE, campus de Cascavel and was aimed at developing a computer program to simulate and scale, optimally, a system of solar water heating. To determine the efficiency parameters of the system were installed three solar collectors of 1.05 m2 each, brand Pro Sol, coupled to a thermal res

3. Designing a neural network for closed thermosyphon with nanofluid using a genetic algorithm
Heat transfer of a silver/water nanofluid in a two-phase closed thermosyphon that is thermally enhanced by magnetic field has been predicted by an optimized artificial Neural Network. Artificial neural network is a technique with flexible mathematical structure that is capable of identifying complex non-linear relationships between input and output data. A m

5. Estudo de desempenho do aquecedor solar de baixo custo
One alternative to reduce consumption of electric energy to heat water will be popularize the use of solar energy. This work comes to contribute of studies about the Low Cost Solar Heater , ASBC, which is a new concept of solar water heater for home, all made by polymeric materials with relatively small investment and can be built manually. The plate of the

6. Análise de termossifões que operam com mercúrio em altas temperaturas
Thermosyphons are high thermal conductivity devices that can transfer high quantities of heat when subjected to small temperature gradients. In its most simple form, a thermosyphon is a hollow evacuated metal pipe, charged by a pre-determined amount of an appropriate working fluid. It can be divided into three main sections: evaporator, where the heat is del

7. Sintese otimizada de sistemas de aquecimento solar de agua
The optimal design of a solar water heater is regarded as achieved when the set of design variables is such that produces the minimum cost of the equipment during its life-cycle. For summing up this cost, it is necessary to take account of acquisition costs, maintenance costs and expenses with auxiliary energy. In this work, a computational procedure for fin
