Systems and methods for reducing the capital and operating costs of a smelting process system and improving the environmental impact of the smelting process using an IGT system to remove and filter environmentally hazardous gases and particulates from each electrolytic cell in the smelting process system. A system for smelting alumina, which comprises: i) an electrolytic cell comprising a housing wherein an upper area of the housing represents a superstructure; ii) a porous floor within the superstructure for supporting a fluidized bed comprising at least one of non-fluorinated alumina and fluorinated alumina; and iii) a ventilation system operatively connecting an opening in the superstructure to an open environment outside the electrolytic cell, wherein the ventilation system comprises a scrubbed process gas plenum positioned within the superstructure above the porous floor and a scrubbed process gas duct. |
