12 Apr 2013 Oil sands recovery processes include extraction and separation systems Bitumen also requires additional upgrading before it can be refined.

Upgrading may involve multiple processes: Vacuum distillation to separate lighter fractions, leaving behind a residue with molecular weights over 400. De-asphalting the vacuum distillation residue to remove the highest molecular weight alicyclic compounds, which precipitate as black/brown asphaltenes when the mixture is dissolved in C 3 –C 7 alkanes , leaving "de-asphalted oil" (DAO) in solution. The purpose of upgrading is to transform bitumen into synthetic crude oil (SCO) which can be refined and marketed as consumer products such as diesel and gasoline. Upgrading processes involve either adding hydrogen or removing carbon from the bitumen to create SCO. Canadian Natural’s oil sands mining portfolio includes its 70% operated working interest in the AOSP mines and 70% non-operated interest in the Scotford Upgrader, located north of Edmonton. Combined, the two mines at the AOSP produce diluted bitumen via a paraffinic froth treatment process. Suncor’s Upgrading operations process bitumen into higher-value synthetic crude oil and diesel fuel using two upgraders at its oil sands site in Fort McMurray. Suncor also operates upgrading assets at its Edmonton refinery. Suncor produces bitumen in two ways: Surface mining. We use large trucks and shovels to extract the oil sands. Upgrading is a process by which bitumen is transformed into light oil by fractionation and chemical treatment, removing virtually all traces of sulphur and heavy metals. Upgraders have 5 basic unit operations: (1) diluent recovery, (2) H:C ratio upgrading through hydrogen addition or carbon rejection, (3) fractionation or cracking of heavy oil into light oil, (4) removal of impurities and (5) product blending.

Tar sands oil upgrading technology. so refiners will need to understand them and be prepared for the changes needed to process them. Origin and characterisation of tar sands oils The characteristics of tar sands oils are somewhat unique. In order to understand the nature of these oils, it is interesting to consider their origin.

16 Dec 2016 In Alberta 78% of mined oil sands were also upgraded in year 2015, a process requiring additional water. Data on upgrading water requirements

Upgrading of the Oil Sands Bitumen recovered from the oil sands is a complex mixture of hydrocarbons, and contains “impurities” such as sulphur, nitrogen, and trace metals such as vanadium. Upgrading is the process of separating and modifying the components of bitumen into various petroleum products or raw materials for further processing.

Facts about these impacts are available at Oil Sands Reality Check. Refining Tar Sands. This site focuses on the refineries that process tar sands crude in the USA and Canada. The refining of tar sands crude is a particularly intensive and polluting process and has increased dramatically in recent years.

Current oil sands extraction and upgrading processes, which use natural gas as an energy and raw material source for hydrogen used in the production of  Alberta, Canada, is home to the largest known oil sands deposits, underlying about Once the bitumen is separated from the ore, it is “upgraded” through the gas is added to enable the material to be pumped to a refinery for processing.
