Multi Point Feed (MPF) Technology

The use of MPF 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 MPF 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. MPF technology is an effective solution to reducing a smelters carbon footprint and lowering operational costs.

High Performance Anode Assemblies (HPAA) – Patented Technology

Using the HPAA in place of a conventional anode assembly allows primary aluminum facilities to reach better efficiency in power consumption by operating at lower temperatures and lower voltage drop. This brings with it better operating stability of the aluminum reduction cell as well as bringing down the maintenance cost of anode stubs. The proprietary MetSol High Performance Anode Assembly allows significant voltage savings while reducing carbon consumption. Operating at low resistance and high heat extraction, the MetSol HPAA provides opportunities for smelters to further increase production.

Copper Cored Collector Bar (CCCB) Technology

A proprietary technology capable of reducing cell operating voltage by over 100 mV and increasing operating current by at least 10%.
Technology successfully piloted at a smelter for 3 years with excellent performance. Results reveal 100 mV voltage reduction with decreased cathode erosion, hence increase in potlife.
Technology is focused on facilitating current increase to increasing production from existing cells.
Provides operating advantages, but are difficult to restart. Locating proper Fe/Cu transition is critical. Suitable for power modulation.
Reduces cathode voltage drop, but does not save energy, unless current is increased, or collector bar size reduced.
Manufacturing of CCCB is crucial:
Need to cope with thermal cycling and creep
Maintenance of structural/electrical integrity during operation and shutdown
Tight is not necessarily good – system must have elasticity and this is hard to achieve at 1000 °C.
