Bio-SNG as fuel in steel industry heating furnaces-integration of a biomass gasifier with a steel plant
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.
