AP60 still uses carbon anodes, so the 'low carbon' win is mostly Hydro-Québec power and efficiency; what anode effect rate and HF capture are they targeting at the fume treatment center during ramp-up? New potlines are an alarm flood unless alumina feed and crust-breaker interlocks are tight; are they running adaptive feed control to hold bath ratio and cut AE spikes?
