This study describes a model (MIKADO) to analyse options to reduce the environmental impact of aluminium die casting. This model will take a company perspective, so that it can be used as a decision-support tool for the environmental management of a plant. MIKADO can be used to perform scena...
of prebake anode,1 tonne of aluminium ingot can be produced(the material reduce about 49%)which are processed by supporting of 1.57x10 MWh of electricity and 3.78x10 litre of diesel fuel as the energy source.The significant environmental impacts consist of tailings(1.22x10 m3)to produce 1 ...
their fossil fuel counterparts. Photovoltaic power requires up to 40 times more copper than fossil fuel combustion, and wind power up to 14 times more iron7. More than 20 energy transition metals (ETMs), including iron, copper, aluminium, nickel, lithium, cobalt, platinum, silver and rare ...
摘要: The process for anodizing a workpiece of aluminum or aluminum alloys provides for the use of the workpiece as the anode of an electrolytic cell in the presence of an aqueous acid solution which contains from 10 to 200 g sulfuric acid and from 5 to 200 g L(+)-tartaric acid....
(2) to elucidate the leaching characteristics of heavy metals in the tailings through batch and column experiments; (3) to identify the primary factors controlling heavy metal leaching by using correlation analysis; (4) to investigate the impact of rainfall on tailings and the impact of heavy ...
• Downward movement of dust laden gas from top substantially reduces the dust loading on filter bags and assists the dislodged dust to fall into the hopper. • Dust laden gas enters through air entry bustle and gets distributed from all 4 sides. This avoids sudden impact on bags, which...
Additionally, note that the impact of disposing of waste bags was evaluated as part of mask end-of-life, and the replacement of straps was only considered for rigid half masks (P6–7) (although there is potential for replacing straps for FFP respirators, this is not evaluated in this ...
The containers were kept covered with aluminium foil for the duration of the drying, and the sediments were frequently manually stirred using a glass spatula to avoid clumping of the sediment into hard aggregates and to help homogenise the sample. Subsamples of 225 g (dry weight (d.w.)) ...
摘要:In order to retard geminate recombination in dye sensitized p-type NiO solar cells, surface treatment by aluminium alkoxide to form a thin insulating layer was applied. Open circuit voltage, short circuit current density, and energy conversion efficiency of the cell were increas...
