Producing high-silicon alloys in submerged arc furnaces involves the generation of an intermediate process gas, comprising silicon monoxide and carbon monoxide, which can lead to environmental challenges due to combustion byproducts. This study aimed to investigate the composition of tapping gas from a silicon furnace during an industrial measurement campaign at the Elkem Thamshavn plant in Norway. Over a three-day period, the gas extracted during tapping was analyzed using Agilent Micro-GC, Protea atmosFIR, and Testo 350, alongside dust concentration measurements with a LaserDust instrument from NEO Monitors. Existing flow and temperature data from the plant were utilized to calculate mass and energy flows, and linear regression analyses were performed to identify predictors of NO X formation in the tapping gas. The findings revealed that the relationship between total energy added to the tapping gas and NO X exhibited the best correlation, highlighting critical insights for managing emissions and improving operational efficiency in submerged arc furnaces. This research contributes towards understanding the environmental impact of silicon production and offers potential pathways for mitigating atmospheric pollution.
