This company is focused on to the development and commercialization of a new sulphur removal and upgrading technology called DSU®. DSU® uses molten sodium to significantly reduce the levels of sulphur, metals, acid (TAN) and asphaltenes in heavy oil feedstocks, including oil sands bitumen. DSU® also significantly increases the API gravity of the feedstocks while achieving a relatively higher yield compared to conventional upgrading technologies (i.e. no large piles of coke or asphaltenes are left behind).
