U.S. patent office to issue another patent to Sulfex™ Desulfurization Technology

Speaking at COP28 UAE in Dubai, Alternative Environmental Technologies Director, Masoud Emami said “As our transition and journey to renewable and green energies will be fueled by carbon fuels, a key element of achieving our planet’s energy transition goals (net-zero) will be curbing emissions from current production of carbon fuels. Adoption of new technology advancements such as Sulfex™ Desulfurization will help to significantly reduce refining emissions and have a positive impact on the refineries’ bottom line. For example, if all hydrotreaters in the world were replaced with Sulfex™, it would eliminate the equivalence of Germany’s CO2 footprint.”

As AET has continued to work on Heavy Fuel Oil (“HFO”) desulfurization methods, new research and development findings have been applied to its distillate desulfurization methods. The newest development utilizes a reaction control fluid to control the stepwise oxidation required to obtain low oxidant consumption levels in the desulfurization of distillate fuels. Initially developed for HFO desulfurization, in distillate fuel desulfurization the reaction control fluid allows for the almost complete recirculation of the acid catalysts and other modifying reagents, thus further reducing reagent costs.
