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. 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.

Abstract Results of an experimental investigation of bitumen recovery from Athabasca oil sand, using solvents in conjunction with steam, are discussed. Most of 

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). 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. 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. 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.

9 Nov 2019 Oil recovery in the oil sands uses two main methods: mining or in situ, the bitumen (oil) is separated from the other components such as sand, 

7 Oct 2013 Risks of steam-assisted bitumen recovery are too little discussed, experts say. Oil sands are also known as tar sands and bituminous sands, are complex mixtures of sand, clays, water and bitumen, which is "heavy" and highly viscous oil. 27 Aug 2015 Bitumen recovery from Canadian oil sands using water-based extraction processes involves a complex, multiphase slurry system consisting of  Three important factors affecting bitumen recovery are as follows: 1. Ore Feed Quality. 2. Oil Sands Throughput. 3. Process Temperature.

The most commonly known unconventional oils --oil sands Lower bitumen recovery rates: Recovery rates for in-situ facilities can vary greatly, typically from 40 to 60%. Despite significant technological improvements in recent years, in-situ recovery rates are still much lower than mining operations, which normally recover over 90% of the bitumen contained in the oil sands.
