Alstom will design, engineer, supply, install and commission two Gas Treatment Plants and one Fume Treatment plant at the smelter.

The plants, due on stream in 2013 and 2014, will capture, filter and recycle corrosive gas produced by the smelter, notably hydrogen fluoride, improving air quality and conforming to environmental requirements.

Alstom had also installed four Gas Treatment Plants and two Fume Treatment Plants for phase one of the Emal smelter. The systems were commissioned in 2010 and are the largest installed in any smelter worldwide.

The Emal smelter complex project is the largest industrial project outside the oil and gas industry in the UAE. Phase two will increase aluminium production from the smelter by 600kt.
