Over the years, there has been growing concerns in climate change and environmental risk due to Green House Gas (GHG) emissions. Iron and steel industry remain as one of the largest energy consuming sector in Asia that accounts for more than 20% of the overall energy consumption. To reduce and control GHG emissions, regulators will impose stricter air pollution and energy efficient targets for the iron and steel industry. This creates a strong motivation for companies to improve their processes, shift to lower carbon substitutes, and enhanced energy efficient technologies. Effective management of air borne emissions can be achieved by systemic approach with emphasis on prevention, containment and treatment. Process optimization, energy assessment, industry bench-marking and usage of new technology are the four main pillars that can be used to define potential reduction in energy usage and flue emissions. These objectives can work hand in hand with energy conservation and cost reduction that provides commercial attractiveness to any iron and steel company. This paper will discuss the practical approach on air emission assessment and potential waste gas heat recovery process that has been adopted in the industry.
