20110180459 | METHODS FOR EXTRACTING BITUMEN FROM BITUMINOUS MATERIAL - Methods for preparing solvent-dry, stackable tailings. The method can include the steps of adding a first quantity of first solvent to a bitumen material to form a first mixture, separating a first quantity of bitumen-enriched solvent from the first mixture and thereby creating first solvent-wet tailings, adding a quantity of second solvent to first solvent-wet tailings to separate a first quantity of first solvent component from the first solvent-wet tailings and thereby producing second solvent-wet tailings, and adding a quantity of water to the second solvent-wet tailings to separate a first quantity of second solvent component from the second solvent-wet tailings and thereby forming solvent-dry, stackable tailings. | 07-28-2011 |
20120152809 | Methods and Apparatus for Bitumen Extraction - Methods and system for extracting bitumen can include the use of a mixing drum for spraying solvent over bituminous material to help dissolve bitumen and create a bitumen-laden solvent phase that can be separated from the non-bituminous components of the bituminous material. The mixing drum can be rotating during the spraying step to help promote dissolution of bitumen. The mixing drum can also include an internal screen for separating bitumen-laden solvent from the non-bituminous material. In some embodiments, two or more mixing drums are used in series, with the non-bituminous material from the first mixing drum being sprayed with additional solvent in the second mixing drum and bitumen laden solvent from the second mixing drum being used as the solvent sprayed over bituminous material in the first mixing drum. Hydrocyclones can also be incorporated in the in system and methods for increased extraction efficiency. | 06-21-2012 |
20130026077 | Methods and Apparatus for Bitumen Extraction - A bitumen extraction method can include the use of a two or more mixing drums aligned in series for spraying solvent over bituminous material and/or tailings loaded in the mixing drums while the mixing drums rotate. Such mixing can result in the dissolution of bitumen into the solvent, which then allows for the separation of a “dilbit” stream from the bituminous material. | 01-31-2013 |
20130026078 | Methods for Extracting Bitumen From Bituminous Material - Methods for preparing solvent-dry, stackable tailings. The method can include the steps of adding a first quantity of solvent to a bitumen material to form a first mixture, separating a first quantity of bitumen-enriched solvent from the first mixture and thereby creating solvent-wet tailings, and adding a quantity of water to the solvent-wet tailings to separate a solvent component from the solvent-wet tailings and thereby forming solvent-dry, stackable tailings. The solvent used in the methods can include paraffinic solvent, such as pentane. | 01-31-2013 |
20130092599 | METHODS AND SYSTEMS FOR UPGRADING HYDROCARBON - Methods and systems of upgrading hydrocarbon material, such as bituminous material, are described. The methods and systems can reduce or eliminate the need for the use of atmospheric and/or vacuum distillation towers by instead using clyconic separation apparatus. The methods and systems can include the use of one or more cyclonic separation apparatus aligned in series in order to separate out a high boiling point fraction of the hydrocarbon material and then upgrading the high boiling point hydrocarbon material in a nozzle reactor. | 04-18-2013 |
20130161238 | Methods and Systems for Removing Material from Bitumen-Containing Solvent - Methods and systems for preparing bitumen-laden solvent for downstream processing are described. The bitumen-laden solvent can be treated with various materials, such as water and emulsion breakers, followed by treating the bitumen-laden solvent in a desalter. The desalted bitumen-laden solvent can then be subjected to downstream processing, such as upgrading in a nozzle reactor. | 06-27-2013 |
20130251597 | NOZZLE REACTOR AND METHOD OF USE - A nozzle reactor includes a passage having one or more regions with a converging-diverging shape. The nozzle reactor accelerates a reacting fluid to supersonic velocities and mixes it with a feed material. The reacting fluid and the feed material may be pre-heated. The high speed collision between the reacting fluid and the feed material at elevated temperatures causes the materials to react. | 09-26-2013 |
20130341245 | Methods and Systems for Upgrading Hydrocarbon Residuum - A hydrocarbon upgrading method is described. The method can generally include a step of providing a nozzle reactor, a step of injecting hydrocarbon residuum into the feed passage of the nozzle reactor, and a step of injecting a cracking material into the main passage of the nozzle reactor, and a step of collecting a product stream exiting the exit opening of the main passage of the nozzle reactor. The hydrocarbon residuum used in the method can be obtained from a hydroconversion-type upgrader, such as an ebullating bed hydrocracker. | 12-26-2013 |
