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 most efficient after-treatment technology for reducing harmful NOx emissions from stationary and mobile sources of diesel exhaust is the selective catalytic reduction (SCR) of NOx with ammonia (NH3). Vanadium-based SCR catalysts reduce NOx selectively ...

Carbon capture & sequestration (CCS) could reduce CO2 emissions from large fossil-fuel power plants on the short term, but the high energy penalty of the process hinders its industrial deployment. Moreover, the utility of nanoporous materials, known to be ...
Modeling of the kinetics of the synthesis process for calcium sulfate alpha-hemihydrate from gypsum formed by flue gas desulfurization (FGD) is important to produce high-performance products with minimal costs and production cycles under hydrothermal condi ...
The process of carbon capture and sequestration has been proposed as a method of mitigating the build-up of greenhouse gases in the atmosphere. If implemented, the cost of electricity generated by a fossil fuel-burning power plant would rise substantially, ...
A significant part of the cost for carbon capture and storage ( CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific ...
Results are presented that explore the dynamic structural changes occurring in two highly flexible nanocryst. metal-org. framework (MOF) compds. during the adsorption and desorption of pure gases and binary mixts. The Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4 ...
A concise one dimensional thermal-hydraulic two-fluid model is presented for the numerical prediction of sulphur dioxide absorption from the flue gas onto drops of the water-limestone slurry in the vertical spray tower absorber. The model is based on mass, ...
In this study, we report the morphological and structural properties of amorphous and nanocrystalline Si thin films deposited by inductively coupled plasma-assisted chemical vapor deposition (ICP-CVD) technique at low substrate temperatures using H-2 dilut ...
