Medium- and low-voltage planning of radial electric power distribution systems considering reliability
(2017-06-22)
This study proposes a new methodology to carry out distribution network planning considering medium-voltage (MV) and low-voltage (LV) systems. The integrated planning problem of a MV/LV distribution system is formulated ...
Optimized harvest scheduling in eucalyptus plantations under operational, spatial and climatic constraints
(IPEF-INST PESQUISAS ESTUDOS FLORESTAIS, 2010)
The representation of sustainability concerns in industrial forests management plans, in relation to environmental, social and economic aspects, involve a great amount of details when analyzing and understanding the ...
Recycling a hydrogen rich residual stream to the power and steam plant
(Pergamon-Elsevier Science Ltd, 2010-06)
The benefits of using a residual hydrogen rich stream as a clean combustion fuel in order to reduce Carbon dioxide emissions and cost is quantified. A residual stream containing 86% of hydrogen, coming from the top of the ...
Optimal synthesis of Fenton reactor networks for phenol degradation
(INST CHEMICAL ENGINEERS, 2011)
There is an increasing need to treat effluents contaminated with phenol with advanced oxidation processes (AOPs) to minimize their impact on the environment as well as on bacteriological populations of other wastewater ...
