  • Patent number: 10519379
    Abstract: Techniques are described for producing a bitumen product and recovering solvent from a solvent-diluted heavy hydrocarbon stream, which can have configurations and operation of an indirect heat exchanger to enhance performance. The system can have three solvent recovery stages. The indirect heat exchanger can have a location and operation to mitigate risks associated with exchanger failures. The solvent-diluted hydrocarbon stream can be preheated with a downstream solvent-depleted stream, and the pressure of the latter can be higher than that of the former to avoid solvent leaking into the hydrocarbon-enriched stream. The heat exchanger can be located in between the second and third stages, so that solvent leaked into the second stage output can be removed in the third stage so that the final product hydrocarbon stream can remain at low solvent contents.

  • Patent number: 10508242
    Abstract: This invention provides a process for producing a crude oil composition from oil sand using a solvent comprised of a hydrocarbon mixture to extract or remove only a portion of the bitumen on the oil sand. The solvent type and the manner by which the extraction process is carried out has substantial impact on the quality of the extracted oil component. The solvent is designed so that it has the desired Hansen solubility parameters that enable the partial extraction of the desired oil composition. The solvent is further designed so that it can be comprised of multiple hydrocarbons having the appropriate boiling point ranges that enable the solvent to be easily recovered and recycle, without the need to externally provide for solvent make-up.

  • Patent number: 10401087
    Abstract: A process for separating solvent from spent oil sand solids involves drying the solids using superheated steam, and thereby producing a vapor comprising the vaporized solvent and vaporized water. The vapor is conveyed through a hot side of a first heat exchanger to produce a cooled stream comprising condensed solvent and condensed water, while a water stream is conveyed under vacuum through a cold side of the first heat exchanger to produce steam. A vacuum blower that applies the vacuum may also compress the steam to adiabatically heat the steam, before the steam is further heated by a steam superheater. The condensed water is separated from the cooled stream, and used in producing the water stream that is conveyed through the cold side of the heat exchanger, as the process continues. The steam is used in producing the superheated steam for drying the solids, as the process continues.

A first inclined auger (104) receives the material from hopper (102) at its lower inlet port and conveys the material upwards dropping it into a hopper (106) and then to a unit (107) either of which may include a crasher (106). Unit (107) includes an eductor (109) which feeds the screened and treated sand slurry to desanding units (112) such as hydro cyclones. The underflow from the desanders is sent to an auger tank's (114) first compartment (113) while the overflow is sent to its second compartment (115) where a flow distributing conduit (117) that disperses it over the surface of both compartments (113), (115). The auger tank (114) employs horizontal augers (116) that are arterial both the first and second compartments (113) and (114).

  • Patent number: 9068124
    Abstract: The invention is directed to a process for extracting bitumen from poor oil sand ore involving mixing the poor oil sand ore with heated water to produce a slurry, and conditioning the slurry to yield a poor ore stream. In a separate train, good oil sand ore is mixed with heated water to produce a slurry, and conditioned to yield a good ore stream. Both the conditioned poor ore and good ore streams are combined in specified proportions to yield a blended slurry which is then fed to a primary separation vessel to produce primary bitumen froth.

    Abstract: A method, and use of, a surfactant is provided for reducing the total acid number (TAN) of produced hydrocarbons. The method may include introducing a surfactant to produced hydrocarbons, separating the surfactant from the produced hydrocarbons, and removing the surfactant and associated acid from the hydrocarbons. The cloud point of the surfactant may be used in the separating step of the method, and removal of the precipitate from the hydrocarbons may reduce the TAN of the hydrocarbons. The separation step may include forming an aqueous or intermediate phase that comprises the surfactant and associated acid.

    Abstract: A method for desorption of bitumen from clay particles. Also a method for the desorption of asphaltenes from clay particles and a method for the desorption of bituminous fractions from mature fine tails (MFT). The method for desorption of bitumen from clay particles involves interacting, in a suitable organic solvent, a clay-bitumen composite with a compound capable of stabilizing the bitumen in the organic solvent and adsorbing to clay particles such that the compound replaces the bitumen in the clay-bitumen composite. A substantial amount of the compound that is capable of stabilizing the bitumen in the organic solvent is recovered with the clay particles, while the bitumen is released. Similarly, the method for desorption of asphaltenes from clay particles also involves interacting a clay-asphaltene composite with a compound capable of stabilizing the asphaltenes in an organic solvent, recovering the compound with the clay particles, and releasing the asphaltenes into solution.

  • Patent number: 9023197
    Abstract: A method of extracting bitumen from bituminous material. In some embodiments, the method may include loading a bitumen material in a column, followed by feeding a first quantity of solvent into the column. The method may also include collecting the bitumen-enriched solvent exiting the column. A quantity of the bitumen-enriched solvent may then be fed into the column. In some embodiments, the method may include simultaneously loading bitumen material and a solvent in a column, followed by feeding additional solvent into the column. The method may also include collecting bitumen-enriched solvent exiting the column, and feeding a quantity of the bitumen-enriched solvent into the column.

  • Publication number: 20150101962
    Abstract: Embodiments of a feedwell discharge a solvent treated bitumen-containing froth feed to a froth settling vessel at a Richardson number less than 1.0. Feed is discharged from feedwell inlets to the vessel, either located at a center of the vessel or at a perimeter wall of the vessel along a substantially horizontal path across the vessel. The high velocity maximizes the horizontal path. As the velocity is reduced along the path and as a result of collision in the vessel with the perimeter wall or with feed entering the vessel from an opposing inlet, the feed separates into diluted bitumen and solvent which rises in the vessel for discharge as an overflow product and a waste stream, comprising water, solids and asphaltenes, which settles to the bottom of the vessel to be discharged as an underflow. A relatively uniform clarification zone forms above the inlets submerged in the vessel.

  • Publication number: 20150090641
    Abstract: Disclosed are processes for extracting deasphalted crude oil from oil sand. Deasphalted crude oil can be extracted using a hydrocarbon recycle solvent stream having specified Hansen blend parameters, with the oil sand being contacted with the hydrocarbon recycle solvent stream in a contact zone of a vessel to separate not greater than 80 wt % of the bitumen present on the oil sand. The separated bitumen is considered a deasphalted crude oil stream, since it has an asphaltenes content substantially lower than that of the total bitumen initially present on the oil sand. The deasphalted crude oil stream can be treated using a hydrotreating catalyst or catalytic cracking catalyst to produce transportation fuel.

    Abstract: An improved composition for recovering bitumen from oil sands is used in the traditional “hot water” extraction process. An aliquot of a solvent mixture is mixed with bitumen ore and water. A pH builder is added and following mixing primary and secondary froths are recovered. The solvent mixture contains a monoterpene, nonionic surfactant, a short chain alcohol and a short chain ketone. Primary and secondary froth recovery is at least 80% at temperatures of about 35° C. Only very small amounts of solvent are used, and all solvents are biodegradable.
