Leverage the power of DSU®technology
Enlighten’s DSU® technology (powered by NaSICON) is a disruptive new process for reducing sulphur and metals in heavy oils to make clean, low-sulphur fuel oil for the marine market.
Processes bottom-of-the barrel feedstocks
DSU® can process a wide range of heavy, high sulphur and metal feedstocks with ease.
High product yield
The DSU® process has high yields (over 95%) that exceed those of coking processes. Plus, energy density is retained – ideal for low sulphur fuel oil markets.
Removes difficult sulphur species
DSU® removes sulphur from deeply hydroprocessed residues, with preferential removal of asphaltene sulphur – a typical challenge for conventional residue hydrotreating.
Low environmental footprint
The DSU® process has low direct emissions. The majority of the emissions are indirect and related to the power source.
Cleaning up our oceans
DSU® technology has been de-risked and is moving towards commercialization with the CleanSeas demonstration project. The CleanSeas plant will use the low emissions DSU® process to create clean, low-sulphur fuel oil that can meet and even exceed the new IMO 2020 marine fuel standards.
Improving refinery yields
DSU® technology can also be used as a refinery pre-treatment process to produce more high-value products from difficult feedstocks.
