Reducing greenhouse gas emissions

Solios Environnement has been investigating ways of reducing emissions from its gas treatment centres. One method is to calculate a carbon balance to identify major emission sources during
manufacture and operation and then actions taken to reduce the total carbon equivalent arising from the gas treatment centres. By El Hani Bouhabila*

An Overview of Sohar Aluminium’s Anode Baking Furnace Operation

The Sohar Aluminium anode baking furnace was commissioned in 2008, and furnace performance since has remained at excellent levels in terms of gas consumption, baking level, fire productivity, tar emissions and firing cycle range.

Some of the challenges in achieving these results are discussed.

Etching effects and the formation of Streaking Defects on Al Extrusions

Surface defects such as streaking are often present on anodized extrusions of 6xxx series alloys. The streak defect is the result of a difference in intensity and diffuse nature of the reflected light compared
to the surrounding material, and is caused by an inhomogeneous distribution of surface imperfections produced during etching. Hence, the etching treatment is an important process step to influence the
formation and severity of streak defects on aluminum extrusions.
