US-based KBR has been awarded a contract by Saudi Aramco Lubricating Oil Refining Company (Luberef) to implement its solvent deasphalting (SDA) technology, ROSE, for Luberef's Yanbu refinery expansion project.
Solvent deasphalting (SDA) processes use light hydrocarbons such as propane, butanes, and pentanes, or a mixture of these to produce deasphalted oil (DAO) that contains lower levels of metals, sulfur, nitrogen, and carbon residue than the bitumen.
Roger Lott commented, "I have verified how PetroSonic's technology can provide a simpler, low cost, and environmentally friendly deasphalting process for removing the asphaltenes along with sulfur and metals from the heavy oil.
Preliminary results indicate that enhanced deasphalting and vis-breaking may be possible.
