Ultrasonication provides an optimal reactive environment, when combined with certain chemicals, that oxidizes the sulphur compounds in the oil phase faster, completely and highly selectively to sulfones. The water soluble catalyst used in our process, further supports the oxidation process.
For heavier fuel oils the larger molecular size of sulfones, now containing a hydrocarbon non-sulfonic fraction much larger, limits solubility considerably.
IUT technology solves this issue by re-configuring and augmenting the amount of ultrasonification and soluble catalyst used (which is a different process to the removal of sulphur in lighter fuel oils) , thereby removing the sulfones leaving the hydrocarbon molecule deprived of sulphur.
Our PC-CUPS partners and laboratory at the University of Calgary have both confirmed and enhanced our process with minimal revisions, reproducing the findings above, which make our technology extremely competitive and applicable to high sulphur fuel oils (HSFO).
“We can comfortably state that IUT’S technology offers advantages over any known technology for oxidative desulphurization and over all the known art of desulphurization of residuals. We are at a critical stage of optimizing our technology for pilot/commercial demonstration. Unless any insurmountable and unexpected obstacles emerge, this technology has the greatest chance of success for the economic desulfurization of HSFO and for any other lighter hydrocarbon fuel.”
