DUBAL technology promoted at industry forum.

Summary: Regional aluminium giant leveraged ARABAL 2010 to promote its in-house developed, proprietary DX Reduction Cell Technology.

DX Reduction Cell Technology -- the in-house developed innovation proprietary to Dubai Aluminium Company Limited ("DUBAL") -- has once again been well received by international industry experts, this time at the 14th International Arab Aluminium Conference and Exhibition ("ARABAL 2010").

So says Ali H A M Al Zarouni (Vice President: Smelter Operations), who delivered a technical presentation on the technology at the biennial event, hosted this year by Aluminium Company of Egypt ("Egyptalum") in Luxor, Egypt from 1 to 3 November.

Al Zarouni's presentation, entitled "DX Reduction Cell Technology - Excellent operating efficiency and superior environmental performance", detailed the development of the technology as a solution to a growing need for lower energy consumption, reduced atmospheric emissions and improved productivity; and showcased both the proven performance attributes and the current operating statistics of DUBAL's DX Reduction Cell Technology.

"Operation at 370kA has been fully consolidated at 95.

5 per cent current efficiency, with daily production yields of 2,873 kilograms of molten aluminium per cell at an average metal purity of 99.

94 per cent and specific energy consumption of 13.

04 kilowatt-hours per kilogram of aluminium produced," says Al Zarouni.

"The reduced use of fossil fuel has obvious resource and environmental conservation benefits; while significantly fewer anode effects compared to lower amperage technologies also contribute to lower perfluorocarbon emissions.

Development work on the next generation DX Reduction Cell Technology is ongoing in pilot cells at DUBAL.

Several enhancements are presently being tested, with the view to raising amperage levels above 400kA -- thereby increasing both energy efficiency and productivity even further.

"DUBAL also had a small display stand in the exhibition held alongside ARABAL 2010.

Again, attention was focused on the development of and benefits offered by DX Reduction Cell Technology.

Senior technical personnel from DUBAL manned the stand, to field questions from delegates and other visitors to the exhibition.

"Strong interest was expressed from delegates, confirming that our technology is attracting the attention of the industry," continues Al Zarouni.

"With DX Reduction Cell Technology being available for licensing, the response is very gratifying.

"DX Reduction Cell Technology has been operational at industrial scale in a dedicated 40-cell potline at DUBAL's Jebel Ali site since early-2008.

The technology has also already been licensed to Emirates Aluminium Company Limited ("EMAL") for the 756-cell EMAL Phase I -- a green-field smelter development at Al Taweelah, Abu Dhabi, which is currently in the process of sequential energizing of the cells and coincident ramp-up of production.

DUBAL has participated in every ARABAL Conference and Exhibition since its inauguration in 1983.

The company serves on the ARABAL Forum and is the first aluminium producer in the region to host four of the biennial ARABAL events to date: 1987, 1995, 2001 and 2008.

The latter event coincided with ARABAL's 25th anniversary, giving DUBAL the rare privilege of hosting the event's silver jubilee year.
