Although the generation of hydrogen fluoride (HF) gas in the aluminum smelting process is unavoidable, it has over the years been controlled through pot design and operation, and most significantly through the design and operation of gas treatment centers (GTC).
At the LMRC, we try to understand the relationship between various factors and the scrubber capacity and efficiency. A dedicated laboratory with lab-scale GTC reactor has been setup to explore the interaction between alumina and HF gas. Modern experimentation techniques are used to test the different factors that influence scrubber capacity and efficiency. The performance of differently calcined aluminas is assessed against simulated parameters in our HF scrubber rig which is fitted with real-time data logging and alarm systems for control and safety.
