The aim of this study is to perform a dynamic modelling and simulation of a Portuguese industrial integrated system in order to analyse the integration and feasibility of the different units, maximizing its efficiency and minimizing its environmental damage, and to study the effect of some operational and atmospheric conditions on the system. For this purpose it was built a dynamic model of the...

The sugar cane industry represents one of the most important economic sectors in Brazil. It produces sugar and ethanol for the internal and external markets. Also, thermal and electric energy are produced for the own factory consumption, using sugar cane bagasse as fuel in cogeneration plants. Almost all the sugar cane factories in Brazil are self-sufficient in terms of energy supply and in the...

In this paper cogeneration benefits applied to a user with a high steam demand are analyzed. The methodology for the feasibility study and the economical analysis of the investment is presented under the Italian legislative framework. The methodology is applied to an actual case and a detailed description and discussion of all data input is provided. Especially this last key point will be faced...

Several decarbonised polygeneration systems exploiting carbon capture and storage (CCS) or CO2 reuse technologies for the conversion of primary resources into clean fuels, chemicals, electricity and heat are systematically analysed for techno-economic feasibility. A process simulation, energy integration and economic analysis based approach has been employed to arrive at a representative set of...
