High Oxygen Injection in Copper & Nickel Converter

Oxygen is used in an oxidation process in Copper/Nickel converters. By injecting enriched air in the liquid matte, the sulphur combines into SO2 which is evacuated in the off-gases.

The higher the oxygen enrichment level, the higher the conversion rate! 

Air Liquide Shrouded concentric Injector (inside O2/annulus N2), has been designed to replace conventional tuyeres in the converter and help you to overcome operational problems including tuyere blockage and refractory erosion at the tuyere line.

American Combustion can design the best operating process for your furnace, build the ALSITM equipment and commission the project.

Benefits

  • Permitted enrichment levels of up to 60% O2
  • Increased converter productivity
  • Reduction in volume of off-gases
  • Elimination of tuyere punching
  • Better treatment of solid (scrap and reverts)
  • Stronger off-gases The shrouded injector technology has already been successfully demonstrated in Hoboken - UNICORE (Belgium), Falconbridge (Canada), TCI (Thailand), ...
