摘要:
Relocatable systems and processes for processing oil sands are described. Relocatable components are employed to permit oil sand processing to be conducted near a mine face, and relocated as the mine face recedes. Flow of the slurry in combination with appropriate water injection through the relocatable pipeline causes agglomeration of fines within the slurry. Bitumen/solvent mixtures can be filtered from the agglomerates within downstream solvent extraction system components. A high quality bitumen product is formed, having water and solids content that exceeds downstream processing and pipeline requirements. Dry tailings may be back-filled in-pit.
摘要:
The present disclosure relates generally to the integration of at least two viscous oil recovery processes (VORPs), at least one of which is a solvent-dominated recovery process (SDRP). Integration of the SDRP and the VORP may be achieved through at least one of: solvent, heat, a production stream, and a viscous oil reservoir.
摘要:
Thermal oil recovery operations, such as SAGD, result in waste heat that is typically released to the environment. Bitumen mining operations require heat input for heating fluids used in the mining process. A method and system of recovering heat from a thermal recovery operation for use in bitumen mining operation is described. A heated donor fluid from a thermal recovery operation is used to heat an acceptor fluid for use in bitumen mining via proximal heat exchange using a power cycle or heat exchange module, such as an ammonia and water based Kalina® Cycle. By utilizing waste heat from thermal recovery operations to heat fluids used in bitumen mining, thermal efficiencies are realized.
