The next projects include the new solvent deasphalting
unit (SDA) in Porvoo, an investment of approximately EUR 200 million.
Instead, the processes of residual condensate destruction are developed due to deasphalting
by bitumens gases .
The second contract was awarded by Saudi Aramco Lubricating Oil Refining Company (Lubref) to Samsung Engineering for expanding the propane deasphalting
unit (6,000 barrels per day) at the Yanbu Refinery.
The US Patent and Trademark Office has granted patent for the 'Enhanced Solvent Deasphalting
Process for Heavy Hydrocarbon Feedstocks Utilising Solid Adsorbent', a process improvement, invented by the head of Clean Fuels Project Team at Saudi Aramco.
Luberef is tendering a smaller package for a propane deasphalter (PDA) unit which will increase its propane deasphalting
from 6,500 b/d to 12,500 b/d, as well as increase the asphalt capacity to 12,000 b/d.
Additionally, surface upgrading processes are capital intensive project as it involves the integration one or more of the following processes such as delayed coking, solvent deasphalting
, visbreaking, thermal and catalytic hydroconversion, etc.
UOP/Foster Wheeler will provide a basic engineering design package for a solvent deasphalting
(SDA) unit at the Sohar Refinery in Oman.
Orpic will use the UOP/Foster Wheeler Solvent Deasphalting
(SDA) process technology to convert heavy crude to low-contaminant deasphalted oil, a product that is further processed in refineries to produce liquefied petroleum gas (LPG), petrol, jet fuel, diesel and propylene.
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.
(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.
