Gas treatment centers 

Fives Solios is working in closed collaboration with its customers to offer the best available technologies and to optimize their operating conditions in order to:

Enrich alumina as required in the process,
Guarantee a low level of emissions during aluminium production.


Fives Solios is one of the pioneers in the process of capturing fluorine by alumina. This process enables to recycle the fluorine emitted from the potshells. Our latest installations can reach exceptional HF emission rates lower than 0.3 mg/Nm3.

The main features of these installations are:

Modular design and easy maintenance
Homogeneous and balanced gas distribution in each module

Modules equipped with large capacity hopper in case of alumina feeding failure
Gentle filter media cleaning using low pressure pulse.
