Fives Solios main objective is to guarantee to its customers a low level of emissions at the time of the operation of their electrolysis pots.
Principle
Fives solios is one of the pioneers in the process of capturing fluorine by alumina. This process can recycle the fluorine emitted from the potshells. Our most modern installations can reach exceptional emission rates lower than 0.3 mg/Nm3 HF. Fives Solios treated all types of pots and are leaders in the treatment of PFPB pots of high intensity. Maintaining a close relationship with the primary aluminium producers helps to permanently optimize the evolving technology in order to meet their needs for an increase in amperage which is essential to keep up their competitiveness.
Fives Solios modern installations are very well adapted to the customer’s needs and are characterized by:
Acidic bath with high content of AlF3
Stringent requirements for the quality/homogeneity of fluorinated alumina
Higher HF emissions at pots outlet
To meet these requirements, Fives Solios installations are designed with special attention to the following key elements:
Modular design and facility to maintain installation centers
Homogeneous and balanced gas distribution in each module (Vibrair, TGT-RI)
Precise regulation for feeding gas and alumina
Modules equipped with large capacity hopper and alumina recirculation by overflowing
Gentle filter media cleaning using low pressure pulse.
