This paper presents an exergy and environmental assessment of a 1000 metric t/day ammonia production plant based on the steam methane reforming (SMR) process, including the syngas production, purification (CO2 capture) and compression units, as well as the ...
The emission of selenium from coal gasification processes can cause harm to the environment and downstream equipment. With upcoming legislation, reliable detection as well as control of such gas species become crucial. This study therefore addresses the de ...
Conceived by Switzerland’s Ecole Polytechnique Fédérale de Lausanne, Clip-Air proposes a plane with a single flying wing encompassing the airframe, cockpit, and three engines, attached to a maximum of three interchangeable capsules a more flexible and effi ...
Energy demand and economic development are intrinsically linked. Earlier economic development came at the price of serious environmental pollution, posing a risk to life on earth. Thus, a transition from fossil to renewable energy is needed. Among the rene ...
The direct transformation of sunlight into fuels and chemicals has attracted considerable attention for the potential impact on the storage of solar energies at large scales and the reduction of CO2 emissions. More than 80% of our current global energy con ...
An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...
The energy demand is increasing as well as the GHG emissions and the fossil fuels depletion. Public awareness on this topic significantly raised up in last decades. Nowadays conversion of residual biomasses in energy represents a real opportunity. However, ...
A 1.5 kWth hybrid solar/autothermal steam gasifier was designed and tested for continuously producing synthesis gas. Time-averaged responses to a series of inlet flow conditions were examined in a high-flux solar simulator. The gasifier consisted of a SiC ...
In this work, a comparative exergy and environmental analysis of the vehicle fuel end use is presented. This analysis comprises petroleum and natural gas derivatives (including hydrogen), biofuels (ethanol and biodiesel), and their mixtures, besides of the ...
