A well referenced, advanced process

Casale NA2000 is a nitric acid dual-pressure scheme that offers low operating cost in term of specific ammonia consumption and precious metals losses, while ensuring high specific steam/energy export.

These plants can be designed up to 2000 MTD capacity and with nitric acid concentration up to 68%wt.

Specific ammonia consumption ranges from 282 to 284 kg/MT of HNO3.

Key features

  • Dual pressure
  • Reduced ammonia consumption and precious metals losses
  • High nitric acid concentrations
  • Longer campaigns (8 to 12 months)
  • High energy efficiency
  • Wide operating range
  • Low emissions
