Thermal Oxidizing

Thermal Oxidizing

The thermal oxidizing unit receives feed from the tail gas treating unit and the sulfur recovery unit. These feeds are heated and combusted, with fuel gas, to convert all of the remaining compounds into sulfur dioxide, water vapor, carbon dioxide and nitrogen. The hot process gas is then discharged safely to the atmosphere through a tall refractory lined stack. Some units have separate thermal oxidizers and stacks and some include waste heat recovery.

Design optimization can evaluate cost for:

  • Waste heat recovery
  • Integrated thermal oxidizer and stack versus separate equipment
  • Free standing versus supported stack
