IUT: Advancing Innovation in Desulphurization

The IUT Advantage

The Next Generation of Desulphurization

IUT is partnering with fuel traders, other technology providers and ship entities to fast-track the commercialization of the second generation of our technology in order to significantly exceed the 2020 IMO Regulations.

Based on the third party analysis of the tests completed using our new process in conjunction with our ultrasonic technology, there are no other property changes except sulphur. We produce desulphurized fuel while maintaining the specifications of the fuel. In other words, our ultrasonic application specifically targets Sulphur, mitigating any harm to the user’s engine. There is also very minimum product loss as with our targeted process, we are only removing sulphur and not hydrocarbons.

The Essential Theoretical Constructs

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.”

Commercial Validation in U.S. Refining Facility (tested on Natural Gasoline)

The first commercial–scale trials achieved sulfur levels below 20ppm with a basic water wash.

All samples “sweet” by the Doctor Test (ASTM D4952 – 09 Standard Test).

–Method for Qualitative Analysis for Active Sulfur Species in Fuels and Solvents.

Average operating costs were attractive at less than $1/bbl.

Feed rates of up to 3000 BPD natural gasoline having a sulfur range of 150-500ppm .

Trials of 40+ hours of continuous operation demonstrated robustness and stability.
