Description:

SulphCo’s Sonocracking™ technology employs high power ultrasound to accelerate oxidative desulfurization (ODS). For ultra low sulfur applications hydrodesulfurization (HDS) suffers from high hydrogen and energy consumption since severe operating conditions have to be employed to treat the most refractory sulfur compounds. In contrast the high power ultrasound-assisted ODS proceeds under mild reaction conditions resulting in a cost and energy effective alternative to HDS. Preferential reactivity towards different sulfur species can be controlled by the selection of an appropriate catalyst/oxidant system. The low capital cost and small equipment footprint suggest a multitude of potential placement options in a refinery. An attractive deployment of the SonocrackingTM technology exploits the advantages of both HDS and ODS to deliver potentially significant operational, investment avoidance and carbon footprint savings. Similar benefits may be achieved in applications ranging from transmix diesel desulfurization to mercaptan removal to natural gasoline desulfurization.
