ABSTRACT:
Process for purifying the fumes emitted by electrolysis pots for the production of aluminum from fluorinated products, alumina and various components of the electrolysis bath, and for using again these products in the pots. The process consists in sucking the electrolysis fumes from at least a hole provided in the crust, and kept constantly open, by keeping under suction only the area surrounding said hole, in contacting the fumes with alumina, and in reintroducing the products fixed and/or retained on the alumina directly back into the same pot from which they have been emitted. Equipment for accomplishing the process, constitutes a cap placed in contact with the crust in correspondence of the hole, by a reactor of the fluidized bed type, or of the injection "Venturi" type, positioned in correspondence of the pot, with related filter and fan/exhauster.
