In Canada, ICM Inc. announced the issuance of Canadian Patent No. 2,799,409 for its Advanced Oil Separation system. The Canadian AOS patent expires 20 years from an international filing date, expiring on May 11, 2031. ICM’s AOS technology employs both mechanical and chemical separation and delivers significant economic value to an ethanol plant by dramatically increasing a volume of non-food grade oil recovered from the plant’s process streams. ICM’s AOS uses a centrifuge as a mechanical dewatering device to deliver a targeted emulsion concentrate stream for further processing by adding a polar solvent, ethanol, as an emulsion breaking-agent. The ethanol liberates oil trapped in the emulsion concentrate that would not be recovered through other conventional methods.
