Bio-SNG as fuel in steel industry heating furnaces: integration of a biomass gasifier with a steel plant
2012 (English)In: Asia Steel International Conference 2012, 2012Conference paper (Other academic)
Climate change, as a result of anthropogenic greenhouse gas (GHG) emissions, is of great concern for society today. Industry accounts for almost 40% of global CO2 emissions and consequently it is important that this sector investigate options to reduce its CO2 emissions. In this paper, an economic evaluation of integration of a biomass gasifier with a steel plant is performed. Synthetic natural gas (bio-SNG) from the gasifier substitutes liquefied petroleum gas as fuel in the steel plant’s heating furnaces. Eight future market scenarios are used to analyse investment opportunities to integrate production of bio-SNG with a case study steel plant. Results from the analysis show that high fossil fuel prices could make integration of a biomass gasifier and fuel conversion profitable. Moreover, profitability is highly dependent on biomass price. At current price levels, production cost for bio-SNG is 82 EUR/MWh.
