This method consists of a fuel oil extraction process, an oxidation process, a separation process by means of centrifuge, a clean fuel oil recovery process, an ionic liquid recovery process, a utility serving facility, and so on. In which, Ozone (O3) is utilized as oxidant in the oxidation process instead of conventional oxidant, such as Hydrogen Peroxide (H2O2), which enables the oxidant to accelerate the reaction process, but chemical properties of ionic liquid and aromatic, however, will have no change during the process. In the processes of clean fuel oil recovery and ionic liquid recovery, Short Path Evaporator is utilized. The features of this innovation, such as low working temperature and low working pressure, etc, would be capable of providing a good solution when extraction process for deep desulfurization & denitrification is used, furthermore, the features of this innovation could prevent the process from creating secondary pollution problem from emission, and the whole processes will be becoming much safer, energy saving, and running cost then could be also minimized in the mean time. |
