KBR announced today that it has been awarded a contract by Saudi Aramco for its market-leading Supercritical Solvent Deasphalting
(SDA) technology ROSE.
Owing to the tough environmental requirements for plasticizers and their wide usage in the rubber manufacturing industry, eco-friendly plasticizers can be used in tyre blends that are obtained by propane deasphalting
of solvent extracts.
Professional services company KBR Inc (NYSE:KBR) reported on Thursday the receipt of a license and engineering (LBED) contract for its ROSE solvent deasphalting
technology in Chile.
KBR announced that it has been awarded a license and engineering, or LBED, contract by ENAP Refinerias SA, or ENAP, to utilize KBR's ROSE solvent deasphalting
technology at their Bio Bio refinery in Concepcion, Chile.
Therefore, this study focused on evaluating the effects of adding nanoparticles to a typical SDA process with the purpose of enhancing the quality of the DAO and optimizing this procedure using nanotechnology in process of designated enhanced-solvent deasphalting
The formation of nonthermal cracking reservoir bitumen is basically due to oxidation, biodegradation, water washing, and deasphalting
. Biodegradation is thought to be the most common trigger to secondary alteration of hydrocarbon and accounts for most of heavy oil in the world [7-9].
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.
