Thermodynamic and economic analysis of hydrogen production integration in the Brazilian sugar and alcohol industry
(Elsevier B.V., 2014-02-01)
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 ...
Dynamic simulator and model predictive control of an integrated solar combined cycle plant
This paper presents the design and evaluation of a dynamic simulator for an ISCC (integrated solar combined cycle) plant. The design of the simulator is based on the phenomenological equations for both a combined cycle ...
Hydrogen production by glycerol steam-reforming over nickel and nickel-cobalt impregnated on alumina
Hydrogen is a clean energy carrier, and its utilization will reduce environmental problems related to fossil fuels one. Biomass is an inexhaustible renewable source to generate biocompounds. Glycerol, obtained from a ...
Minimization of life cycle greenhouse emissions and cost in the operation of steam and power plants
The main objective of this work is to use environmental and economic objective functions to select the operating conditions of process plants. The operating conditions of a steam and power plant are selected to minimize ...
HYDROGEN FROM BIOMASS GAS STEAM REFORMING FOR LOW TEMPERATURE FUEL CELL: ENERGY AND EXERGY ANALYSIS
(Brazilian Soc Chemical EngSao PauloBrasil, 2009)
Economical analysis of ethanol steam reformer for hydrogen production associated with a sugarcane industry
An expressive amount of produced hydrogen is generated by customers in-situ such as petrochemical, fertilizer and sugarcane industries. However, the most utilized feedstock is natural gas, a non-renewable and fossil fuel. ...
Analysis of the performance of an extraction-condensation steam turbine on a cogeneration system of a Brazilian sugar-alcohol factory
(Natl Technical Univ Athens, 2006-01-01)
In this work a detailed thermodynamic analysis for an extraction-condensation steam turbine capable to drive a 40 MVA electricity generator in a sugar-alcohol factory was carried out. The use of this turbine in the ...
