Initial and Final SO2 Concentrations

Continuous smelting and converting gases contain 20-75 volume% SO2 as they leave the furnace. This is too strong for downstream catalytic SO2 + V2O2 — SO3 oxidation. The heat of oxidation with this strong gas would overheat the catalyst. Chapters 7 and 8. [Pg.31]

For this reason, continuous smelting/converting gas is always diluted with weak process gas (e.g. anode furnace gas) and/or air before it is sent to catalytic SO2 oxidation. [Pg.31]

Metallurgical Process Offgas temperature, K SO2 in offgas, volume Dust in offgas g per Nrn  [Pg.33]

Country Time period Maximum SO2+SO3 (SOJ concentration (parts per million)  [Pg.33]
