Technology Highlights
- Ultrasonic decreases oxidation reaction time and increases sulfur conversion efficiency with very low residence times (
- The oxidized sulfur compounds after treatment exhibit high solubility in water allowing for easy separation of the sulfur from the hydrocarbon stream.
- Instead of complex post-processing separation, removal of the oxidized sulfur compounds can be achieved via a basic water wash.
- Resulting treated hydrocarbon stream has a sulfur content of 10 ppm and potentially less
- More cost effective than traditional hydrodesulphurization (“HDS”)

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
- Capital costs: lower relative to HDS
- Operating costs: low utilities, lower labor, catalyst cost and regeneration use, no hydrogen
- Operating complexity: low pressure, low temperature, safe
- Efficiency: very effective at converting complex compounds abundant in hydrocarbon streams
- Carbon footprint: lower energy use
