Oil sands bitumen recovery
OIL SANDS GEOLOGY AND PROPERTIES OF BITUMEN. About 10% of the world's oil reserves are located in the Alberta oil sands. These deposits are estimated to hold almost 2 trillion barrels of oil, but less than 10% (about 165 billion barrels) can economically be recovered with current technology. Bitumen recovery from oils sand deposits typically uses thermal oil recovery techniques of which steam injection is the most popular. Recovery efforts include thermal methods (steam floods, cyclic steam stimulation, and steam-assisted gravity drainage) as well as nonthermal methods (cold flow with sand production, cyclic solvent process, and vapor-assisted petroleum extraction). The term “oil sands” is a bit of a misnomer. The deposits are saturated with a tarlike substance known as bitumen. A great deal of processing is required to separate this bitumen from the associated soil and other debris. The most common way to recover bitumen from oil sands is through the use of steam to heat the bitumen. NRCan scientists are investigating innovative approaches to separating bitumen from sand. This approach could lead to eliminating the use of water in oil san Skip navigation Bitumen froth treatment is an integrated process step in the Athabasca oil sands bitumen recovery operations. Its objective is to separate mineral solids and water from the bitumen froth. The bitumen froth is diluted with naphthenic or paraffinic solvents to lower its viscosity to facilitate the separation; therefore, bitumen froth treatment is the removal of inorganics (mineral particles and The Clark hot water extraction process is currently used to extract bitumen from mined oil sand ore. This technology is associated with high energy requirement, water consumption, and generation of tailings ponds. Solvent extraction offers an alternative process for bitumen recovery. In this process, oil sand is mixed with solvent to dissolve bitumen. In oil sands, an incremental improvement in bitumen recovery can have dramatic financial benefits. One area of loss occurs in bitumen extraction. Improved recovery occurs by maximizing the fraction of bitumen that is sent to upgrading and conversely minimizing the fraction that escapes to the tailings ponds.
SRUs are similar in design to DRUs (diluent recovery units) used in upgrading or even atmospheric distillation units used in conventional oil refining. SRU circuits consist of flash columns and/or drums, where the bitumen/solvent feed from the FSU circuit is heated in stages, allowing for the solvent to be slowly vapourized.
Handbook on theory and practice of bitumen recovery from Athabasca oil sands: 9781926832036: Books - Amazon.ca. Oil sands recovery processes include extraction and separation systems to remove the bitumen from the sand and water. Oil sands currently represent 40% of 16 Jan 2012 Cyclopentane is a good solvent for extracting bitumen from oil sand. Cyclopentane gives higher bitumen recovery than toluene. To reduce solvent 26 Sep 2019 The 200-barrel diluent recovery unit is modular, meaning it can be scaled up in size. Butler said the cost of shipping solid bitumen was

One area of loss occurs in bitumen extraction. Improved recovery occurs by maximizing the fraction of bitumen that is sent to upgrading and conversely minimizing the fraction that escapes to the tailings ponds. Naphtha Recovery Units (NRU) used in the oil sands are modified versions of traditional flash columns, using temperature and pressure to recover the naphtha. The naphtha-free tailings can then be discharged into the tailings pond. DESIGN & THEORY Oil sands are recovered using two methods, depending on the depth of the reserves. Surface mining is used when bitumen is within 250 feet of the surface. In-situ recovery techniques are used to extract deep deposits of bitumen without removing the soil and materials above it. It is mainly used to extract bitumen in oil sand that is buried too deep below the earth's surface for recovery with a truck and shovel. In situ technology injects steam and chemicals deep beneath
