Featured Project

Converter Retrofit Project

Landmark EPA legislation created new SO2 NAAQS with ambient air concentration limit of 75 ppb SO2. GCT developed the project for Asarco Hayden Smelter from concept through to implementation, commissioning and start-up to significantly reduce SO2 and dust emissions from the smelter.

Key project elements include:

  • 3 New 15’x35′ Converters, complete with ancillary systems including flux and scrap feed systems
  • New hoods and off-gas collection systems to achieve >99% sulfur fixation
  • New wet gas cleaning system for acid plant
  • New Flash Furnace ventilation baghouse based gas collection system
  • Upgrade plant infrastructure including blowers, compressors, cooling towers and electrical substation
  • Retrofit 1911 era building to accommodate larger converters and ancillary systems
