- the invention relates to the production of aluminum by igneous electrolysis. It relates more particularly to the means of confining the gaseous effluents produced during the electrolysis.
- Aluminum metal is produced industrially by igneous electrolysis, namely by electrolysis of alumina in solution in a bath of molten cryolite, called electrolyte bath, according to the well-known Hall-Héroult process.
- the electrolyte bath is contained in cells, called “electrolysis cells", comprising a steel box, which is coated internally with refractory and / or insulating materials, and a cathode assembly located at the bottom of the cell.
- Anodes made of carbonaceous material are partially immersed in the electrolyte bath.
- the assembly formed by an electrolysis tank, its anodes and the electrolyte bath is called an electrolysis cell.
- This device covers the electrolytic cells and includes containment means, which notably include a covering device, and means for suction and chemical treatment of the effluents.

- Known methods for treating effluents include in particular the recovery of fluorinated gases by reaction with alumina.
- the hooding device comprises access means, such as covers, generally removable, and a pouring door, which allow intervention on the tank.
- the hooding device delimits a confined suction zone and in depression relative to the ambient atmosphere, which makes it possible to efficiently recover the effluents. Continuous capture yields of more than 97% are thus obtained in the most modern industrial installations, so that the atmospheric emission rates of fluorinated gaseous products are clearly below the regulatory thresholds.

- the flexible body ensures a certain seal around the anode rod and allows the maintenance of this seal, thanks to the flexibility of the body, despite inevitable variations in the position of the rod.
- the invention makes it possible to appreciably limit the gas exchanges via said free space.
- the support is advantageously in the form of a notch in order to simplify the construction of the leak limiter and allow lateral insertion of an anode rod through the opening of the notch.
- the invention also relates to an electrolysis cell comprising at least one leak limiter according to the invention.
