Qatalum

HAL250 was the technology applied in Hydro's project at Sunndal, Norway. Qatalum has built on the experiences gained in Sunndal, at other Hydro plants, and in the course of the company’s technology development activities.

The cell technology is a top technology product. Aluminium production takes place at 960°C and uses aggressive chemicals. This process is difficult to monitor using normal measurement methods and equipment, so Hydro has therefore developed a special microcomputer for process control.
It is vital that aluminium cell control system functions without fault 24 hours a day, every day, year after year.

The HAL275 technology to be used in Qatalum is an economical and environmental-friendly electrolytic reduction technology. A holistic approach, system knowledge, operational experience and advanced mathematical models have resulted in a compact and highly productive plant with a sound working environment. Highly efficient purification units will be installed. Due to the temperatures involved, there will also be a high degree of mechanization of operation.
