This work refers to a case study on sugar cane mill from Sao Paulo State, in Brazil. It will be analysed the financial benefit acquired through sugar cane bagasse usage as energy source, studying the transformation of this inlet into electrical power, highlighting the greenhouse gas emissions...

Cogeneration may be defined as the simultaneous production of electric power and useful heat from the burning of a single fuel. This technique of combined heat and power production has been applied in both the industrial and tertiary sectors. It has been mainly used because of its overall...

One of the biggest challenges today is to develop clean fuels, which do not emit pollutant and with viable implementation. One of the options currently under study is the hydrogen production process. In this context, this work aims to study the technical and economical aspects of the...

In this work is presented the case that evaluates the possible environmental and economical gains with the application of water solar heating as an alternative for the consumption of natural gas in chemical reactors from cosmetic industries. The proposal consists of pre-heating of water for a...

This work proposes to use thermodynamic modelling, and fuzzy thermoeconomic to optimise the small waste water treatment plant work period concerning to sewage treatment and energy generation through products associated to it. Thermoeconomic optimisation is described as a fuzzy non-linear...

Cement is the main component of concrete, which is, in turn, the second most consumed material on earth, in addition, the cement industry is one of the most intensive energy consumptions. The modern plants often have nominal production capacity exceeding one million tons per year. To produce one...

The Brazilian aluminium industry, classified as energy-intensive, consume alone about 6% of all power generated by hydro-electric power plants, and therein lies much of the problem: needs lots of energy to produce primary aluminium. The aim of this study is to evaluate the strategy of energy...

The growing demand for electrical power and the limited capital invested to provide this power is forcing countries like Brazil to search for new alternatives for electrical power generation. The purpose of this paper is to present a technical and economic study on a 15kW solar plant installed...

This work proposes a technical and economic analysis of the Brazilian matrix energy evaluation, aiming at the evaluation of impacts inherent to technological innovation involved on energy matrix and the sectoral development. Particular attention is given to biomass energy, natural gas, and...
