T.2 Technical Options for Emission Reductions from Inco Thompson Technical Option Improve Existing Gas Cleaning System Description Upgrade close capture hoods, install local baghouses, generally reduce air inleakage and upgrade main ESP. Applicability Comment Possibly already part of Inco’s plans Potential Reduction (%) 20 to 50% of CEPA-toxics 20 – 70 and PM No improvement in SO 2 Capital Cost (million $) Install Acid Plant Treat smelter off-gases in acid plant Justifiable only with smelter modernization and capacity increase Modernize Process Equipment, combined with state-of-the-art gas processing and sulphuric acid production. Replace Roasting and Electric Furnace Smelting with Flash Furnace Continuous Converting Economic Implications. An increase in capacity of about 50% would be needed. Acid prices would have to improve considerably. More research needed > 90% of CEPA-toxics, PM and SO 2 100 - 150 > 90% of CEPA-toxics, PM and SO 2 500 -700 xvii
T.3 Technical Options for Emission Reductions from Falconbridge Sudbury Technical Control Option Install Wet Gas Scrubbing Equipment Install Additional Wet Gas Cleaning and Acid Plant. Description Install scrubber on Electric Furnace, Converting and Slag Cleaning off-gas to recover dust, fumes and SO 2 as a sludge. Pass Electric Furnace, Converter and Slag Cleaning through conventional gas cleaning, acid plant system. Applicability Comment High reagent costs. Would need process equipment modifications to concentrate SO 2 Potential Reduction Capital Cost (%) (million $) > 90% of CEPA-toxics, 50 - 80 PM and SO 2 > 90% of CEPA-toxics, 60 - 90 PM and SO 2 xviii
