At the Karm°y Technology Pilot, Hydro will aim to achieve significant step changes in the specific energy consumption and at the same time meet the lowest emissions. This goals will require energy improvements of all aspects of the production including the power for operating auxiliary equipment.
In this process Hydro selected to combine and integrate the entire material handling and gas treatment systems utilizing the Abart gas treatment system. The paper will describe the solutions selected including the dual duct systems for pot operation, anode cooling box suction, heat exchangers, the Alfeed alumina distribution, fluoride transport, and crushed bath mixing and transport.
Significant technology improvements related to the new integrated heat exchanger will be shared including energy recovery potentials and improvements in HF absorption due to the improved pot gas and alumina mixing in the GTC reactors.
