Desulphurization Relative Difficulty

Sulfur in refined fuel streams generally occurs from the following compounds:

Challenges of Traditional Hydrodesulphurization (“HDS”)

  • Capitalcosts: high
  • Operatingcosts: high utilities, labour, catalyst use, hydrogen
  • Operatingcomplexity: high pressure, high temperature, safety
  • Efficiency:less effective at converting complex cyclic sulfur compounds
  • Carbonfootprint: hydrogen use and energy (heat/pressure) use
