APCTM Advanced Process Control
Advancing Aluminium Pot logic into the 21st century
APCTM (Advanced Process Control) is a PLC based system designed to manage and optimize the alumina feed in a reduction cell for effective mass balance control, enhancing metal production and energy savings while predicting and preventing anode effects.
APCTM is an easy and effective solution to increase Current Efficiency by about 1% on average whilst lowering the pot operating voltage, thereby resulting in a lower power consumption.
The installation of the APCTM system is done in two steps: by assessing existing pot operation data and scoping the installation project, followed by installing, testing and finetuning the customized system.
MPFTM Multi Point Feed Technology
The use of MPFTM leads to improved metal purity (low iron and silicon contents) thereby giving the primary aluminum metal producer flexibility in producing premium products for better revenues. Using MPFTM technology also reduces the frequency and duration of “Anode Effects”, a phenomenon arising from inadequate alumina feeding in the cell, leading to the emission of extremely potent greenhouse gases. MPFTM technology is an effective solution to reducing a smelters carbon footprint and lowering operational costs.
MPFTM can be fitted and yields benefits with all technologies currently in use. Our engineers are looking forward to discussing the details and working out a simulation based on your cell specifics.
The installation for the APCTM covers all hardware such as touch panel, control cabinet, additional sensors, cabling, electronics, CPU and software.
Along with its easy handling the touch panels are robust, modern and can be installed next to the reduction cell together with a control cabinet, housing the electronics and protect them from heat and dust.
APCTM works and yields benefits with all technologies currently in use and was successfully implemented on AP-9, P69 and GAMI.

High Performance Cathode Assemblies (HPCA)
Using the HPCA in place of cast-iron poured at approx. 1300°C allows primary aluminum facilities to improve the current distribution and reinforces vertical current flow in the carbon and graphite blocks. The HPCA consists of electrically compensating plates, contact plugs and a clean sealing paste which connects the cathode blocks and the copper collector bars.
This product is being produced in collaboration with Carbon Savoie.
