VMETS UAOD technology is applicable to different petroleum products including natural gas liquids (NGL), gasoline, kerosene and diesel, reducing the Sulphur content to 10 parts per million (ppm) or less, meeting or exceeding the ultra low sulfur (ULS) transportation fuel standards of most countries and successfully reduced sulfur content in refined oil products by at least 97%.
Ultrasonic Assisted Oxidative Desulphurization
Sulfur in refined fuel streams generally occurs from the following compounds:
| Traditional HDS | VMETS UAOD | |
| Hydrogen addition | Yes | No |
| Pressure | 2000 PSI | 50 PSI or less |
| Temperature | 300-400℃ | 80℃ or less |
| Operating costs | $4-5/bbl. | $ 1.5 / bbl. |
| Movable | No | Yes |
| Modular and capacitive | No | Yes |
| Removal of complex sulphur compounds | Less effective removal of Sulphur in cyclic compounds | Effective with all Sulphur compounds |
| Operation | Complex, several operators | Simple, 1 to 2 operators |
| Effect on octane/cetane number | Reduced | No effect |
