anode effect

anode effect

[′a‚nōd i‚fekt]
(physical chemistry)
A condition produced by polarization of the anode in the electrolysis of fused salts and characterized by a sudden increase in voltage and a corresponding decrease in amperage.

Reducing GHG emissions has been made possible thanks to the modernization of RUSALs enterprises: implementation of the alumina point feeder which reduces the frequency of the anode effect, improvements of the reduction technology and actions taken to improve the energy efficiency of production.

6] during anode effect was undertaken and reported upon in a paper[7] by A Oygard et al.
These are: acceptable alumina dissolution, satisfactory mixing to avoid concentration gradients and a satisfactory rate of alumina increase after anode effect.
In industrial application, when compared to Li bath addition, it was found that the salt containing anode is better wetted by the cryolite-alumina bath, has higher critical current density to inhibit the anode effect, and lower anodic overvoltage as the lithium salt can catalyse the carbon-oxygen reactions.

Advances in the extractive metallurgy of aluminium
In the aluminium industry, reported PFC emissions are known to be associated with momentary process imbalances known as Anode Effects.
We believe our new research is the first of its kind as it aims to tackle emissions from minute changes rather than just reducing Anode Effects that we can all detect today.
EGA to further reduce PFC emissions after record low in 2017
A programme has been initiated to facilitate stricter control over anode effects and thereby reduce PFC emissions.
Dubal efforts ensure cleaner environment
In recent years, this has included introducing new preventative maintenance procedures; alternative anode sizes; and new controls to anticipate and prevent anode effects.
Dubal to lend support to event
The reduced use of fossil fuel has obvious resource and environmental conservation benefits; while significantly fewer anode effects compared to lower amperage technologies also contribute to lower perfluorocarbon emissions.
DUBAL technology promoted at industry forum
In addition to boosting production capacity, the new technology reduces emissions of perfluorocarbons, a greenhouse gas generated in the aluminium smelting process from anode effects, by 96%.
