Shell Canada opts for KBR’s Rose Solvent deasphalting technology
Posted: 27 October 2004
KBR will utilize its Rose Solvent Deasphalting Process for the proposed debottlenecking of Shell Canada's Bitumen Upgrader located in Scotford, Alberta, Canada. The new Rose unit will deasphalt 25,000 barrels per stream day of hydrocracked vacuum residue.
The deasphalted oil (DAO) extracted by the Rose process will be low in contaminants like sulfur, metals and Conradson carbon (CCR) and will be blended either directly or after hydrotreating into the synthetic crude product. The asphaltene product will be blended into fuel oil product. KBR is the engineering, construction and services subsidiary of Halliburton.
“As the premier solvent deasphalting technology, KBR’s Rose process commands more than 75 per cent of the supercritical solvent deasphalting market, and helps upgrading and refining industries improve profit margins,” said Tim Challand, KBR’s vice president of technology. “Through the use of our Rose technology, KBR offers solid, commercially proven and reliable solutions to the expanding upgrader industry, particularly in Canada.”
KBR’s Rose technology is used by refineries for separating high value deasphalted oil (DAO) from heavy aromatic asphaltenes. The DAO is normally converted into valuable transportation fuels through cracking in Fluid Catalytic Cracking (FCC) or hydroprocessing units. The asphaltene product can be used as fuel or for production of products such as road asphaltene or roof shingles. Alternately, the asphaltenes can be converted into pellets and used as fuel in the cement and power industry.
The proposed Albian Heavy Synthetic (AHS) upgrading project is in its front-end engineering phase with the final investment decision planned in mid-2005.
