Definitions
- the field of the invention is that of the treatment of oil sands.
- the invention relates to a process for the treatment of oil sands in a liquid medium, consisting in effecting a phase separation (mineral, hydrocarbons and water) which makes it possible to recover the bitumen with a maximum of yield and consequently to obtain a clean sand. rid of hydrocarbons.
- the invention also relates to devices for implementing such a method.
- Tar sands are hydrocarbon reserves made up of a mixture of heavy oils degraded into bitumens and sand. Typically, the average bitumen content is from 5% to 20% by weight of mineral matter.
- a typical method of exploiting these reserves is extraction in open-pit mines: the oil sand is excavated, and the bitumens are then separated from the sand by washing. These washes consume a lot of water, which has a considerable ecological impact despite the large amount of water recycled, since the wastewater is discharged and lagooned in tailings ponds. purify the water before it is released to the environment. Massive amounts of hot water with added soda and additives are used. These conventional techniques pose major environmental problems.
- cryogenic extraction of oil sands has been the subject of an earlier study by researchers at UWO London Ontario University (Welmers et al 1 - *).
- the technique used is based on a known physical principle: the bitumen fraction of the ore becomes brittle at a temperature below the glass transition temperature ("Tg") of the bitumen.
- Tg glass transition temperature
- the glass transition temperature of the bitumen is between -15 ° C and -40 ° C, and is typically around -20 ° C.
- the bitumen fraction of an oil sand is then divided into fine particles, which are then recovered.
- This process is conventionally called cryogenic extraction.
- Cryogenic extraction can be combined with a mechanical grinding step. This process is then conventionally called cryogenic grinding.
- a particular cryogenic grinding technique implemented by Welmers et al. results from the combination of crushing the frozen bituminous sand by a ball mill that scrapes the surface of a fluidization grid, and attrition (elutriation) produced by a fluidized bed in which the bituminous sand is introduced continuously and fluidized with cooled nitrogen gas. Cooling is achieved by thermal exchange of nitrogen gas with liquid dinitrogen.
- a possible alternative described for this step of separating the fine particles is to grind in the presence of glycol which is still liquid at the process temperature, and whose density is intermediate between the bitumen and the sand.
- the technique described in this patent application consists firstly in agglomerating the bituminous sand, then in grinding the agglomerates obtained, which constitutes two unit operations with a reverse purpose. one of the other, both expensive in energy and material. The practical interest of this method is therefore limited.
- this particle flow typically less than 5 or 10 ⁇ in diameter is subjected to two mechanical separation operations, conventionally used in the powder industry, implementing a zig-zag impactor and an imposed vortex separator, the device implemented being completed in the end by an electrostatic precipitator.
- the method according to CA 2738011 is an entirely mechanical process, in which a low temperature is maintained by constant circulation of cold gas.
- Such a process is characterized by a great complexity, which is necessarily a source of various malfunctions, and therefore implies high costs in terms of implementation, for example related to the high energy consumption, and to probable insufficiencies of operational reliability.
- the handling of dry powders and fuels presents severe risks in terms of industrial safety.
- cryogenic grinding techniques described above which result in the production of an enriched fraction relative to the initial bituminous sand, however, do not make it possible to extract the bitumen with satisfactory material yield and energy efficiency compared to the raw material, and are also very sensitive to the nature of the treated bituminous sand. Indeed, these techniques have a very limited reliability because of the variations of the materials of mining origin to be treated, in particular the variations in composition and mechanical, rheological or physicochemical behavior, related to the location and the mining conditions implemented.
- US 3993555 discloses a technique which associates contacting oil sands from open pit mining with cooled toluene such that the temperature of the mixture is below -19 ° C. Such contacting is carried out either by the use of mixer-settler systems in cascade ("mixer-settlers” in English), or by simple leaching ("leaching" in English). During this operation, cold toluene is used to solubilize the bitumen, which makes it possible to obtain a liquid / solid suspension which is treated downstream, where the liquid is a solution of bitumen and toluene, and where the solid phase is made of sand and ice.
- This suspension still maintained at low temperature, is then subjected to a simple centrifugation or is treated in a centrifugal decanter.
- the liquid phase comprising bitumen and toluene, is recovered, then reheated and subjected to conventional distillation, in order to obtain the separation of the bitumen and toluene, the bitumen remaining at the bottom of the column.
- the toluene is then returned upstream of the extraction line, to be mixed again with oil sands.
- this method has limited performance since, according to US 399355, the recovery rate is only 89%.
- US Patent 4498971 discloses another process for extracting bitumen from oil sands, combining cryogenic grinding with the use of solvents for the separation of bitumen and sand. This process consists in cooling the bituminous sand at a temperature of -60 ° C. (very low, therefore, costly in energy), and in subjecting it to grinding combined with sieving of the resulting solid, with a mesh of 150 ⁇ , then at treat the resulting particles with solvents. Once sieved, the ground bituminous sand is in the form of two classes of particle size respectively smaller than and greater than 150 ⁇ . These two classes undergo two separate pathways of treatment.
- the heavy fraction with a particle size greater than 150 ⁇ , is mixed with n-hexane and leads to obtaining a bitumen, probably deasphalted, at the same time as obtaining a pitch, separated by filtration.
- the light fraction with a particle size of less than 150 ⁇ , is also mixed with n-hexane.
- sand is mixed with pitch, and at the top of the settling tank, a liquid is concentrated which must be filtered in order to separate the mixture of "polar hydrocarbons" and pitch, from liquid composed of deasphalted oil and n-hexane.
- the deasphalted oil liquid / n-hexane is then distilled for the recovery of the solvent n-hexane, from the treatment of the light fraction, for its total recycling. Downstream of these specific treatments of the heavy and light fractions, the two deasphalted bitumen fractions are mixed in line and subjected to final deasphalting, operated with a second solvent, which is n-pentane.
- a process is undeniably complex: the whole of it is operated at low temperature, involves three deasphalting units, a large cryogenic mill, a sieving step, filtration steps with at least three large capacity filters, and uses two paraffinic solvents that must be recovered and recycled. This results in a very expensive process, both in financial investment and energy, and whose performance in carbon yield compared to asphalt oil sand is unsatisfactory.
- the object of the invention is in particular to provide a process for the treatment of oil sands that is simple to implement, and that does not require the use of techniques that are energetically expensive and difficult to exploit, such as deasphalting methods using heavy solvents, grinding and fine sieving, or centrifugation.
- the invention also aims to satisfy at least one of the following objectives:
- the present invention provides, in a first aspect, a method for treating an oil sand, comprising the following steps:
- the bituminous sand is brought into contact with a separation fluid which has the characteristic of being liquid at the operating temperature and the operating pressure.
- This first step is carried out at an operating temperature which is less than or equal to the glass transition temperature of the bitumen.
- an oil sand can undergo two types of physicochemical effects.
- the coefficient of thermal expansion of bitumen is higher than that of a mineral material such as sand or clays.
- the cooling of an oil sand can therefore cause a reduction in the existing cohesion between bituminous fraction and sand.
- the bitumen becoming more brittle than sand, it can then be divided into fine particles, which could then be recovered.
- the oil sand particularly of Canadian origin, may consist of mineral, and in particular grains of sand, surrounded by a film of water, itself embedded in a thin layer bitumen.
- the cooling of the oil sand is then accompanied by the transformation of the water film into a thin film of ice that can facilitate the phenomenon of peeling and release of bitumen.
- the first step of the process according to the invention also comprises mixing the bituminous sand and the separation fluid which have been brought into contact.
- This mixture advantageously makes it possible to impart mechanical energy to the bituminous sand sufficient for this energy, combined with the cooling, to break the adhesion of the bitumen to the mineral material, and thus to detach the bitumen layer from the mineral matter.
- the mixture also makes it possible to deagglomerate the grains of bituminous sand which may optionally be agglomerated.
- the mechanical energy provided by the mixture can also allow a disintegration of the bitumen itself, which facilitates its entrainment by the separation fluid.
- the cooling operations of the oil sand and the supply of mechanical energy are carried out simultaneously with the addition of a separation liquid. Thanks to its physico-chemical properties, and in particular its solvent power, the separation liquid significantly improves the bitumen recovery rate.
- the operating temperature is between -20 ° C and -65 ° C
- the operating pressure is between 5 bar and 25 bar, preferably between 5 bar and 15 bar. The temperature and the operating pressure can be maintained throughout the steps of the treatment process according to the invention.
- the separation fluid is carbon dioxide.
- carbon dioxide C0 2
- C0 2 carbon dioxide
- Another advantage of carbon dioxide for the present invention is related to its thermodynamic properties. Carbon dioxide can indeed be used very easily in the liquid state, as soon as the pressure is greater than 5.18 bar, but also in the solid state under atmospheric pressure, as soon as the temperature reaches -78.5 ° C. In practice, the liquid carbon dioxide is therefore storable and transportable at low temperature ( ⁇ -20 ° C) and medium pressure (between 5 and 18 bar for example).
- the separation fluid is a pure compound or a mixture of compounds belonging to the family of refrigerants conventionally called "freons" and which could be CFCs (chlorofluorocarbons), HCFCs (hydrochlorofluorocarbons) or even HFCs (hydrofluorocarbons).
- Freons CFCs (chlorofluorocarbons), HCFCs (hydrochlorofluorocarbons) or even HFCs (hydrofluorocarbons).
- CFCs chlorofluorocarbons
- HCFCs hydrochlorofluorocarbons
- HFCs hydrofluorocarbons
- the separating fluid may be chosen from liquefied petroleum gases (LPG) such as butane or propane, used pure or as a mixture and possibly containing certain variable proportions of olefinic or diolefinic compounds with carbon numbers. equivalent.
- LPG liquefied petroleum gases
- the separation fluid has a stronger affinity for bitumen than for sand.
- the separation step (2) of the liquid phase and the solid phase is a gravity separation step, carried out in a clarifier located downstream of the capacity.
- the separation fluid is chosen from fluids in which the bitumen is at least partially insoluble and having a density greater than the density of the bitumen but less than the density of the sand. The fact that the separation fluid has a density greater than the density of the bitumen advantageously makes it possible to prevent the bitumen from remixing to the solid phase.
- bitumen fraction is extracted from the supernatant liquid phase by evaporation of the separation fluid, preferably by expansion of the fluid when the fluid is a liquid under pressure.
- the supernatant liquid phase is heterogeneous and comprises a surface layer containing most of the bitumen and a clear liquid phase essentially containing the separation fluid in the liquid state.
- the extraction of bitumen is then carried out by mechanical skimming of the heterogeneous liquid phase.
- Extraction of the bitumen can also be carried out by overflow as is practiced in industrial equipment for the primary separation of bitumen. It is also possible to use a hydrocycloning process to carry out this extraction.
- the contacting step (1) and the separation step (2) are performed using the same device, which can be provided with heating and depressurizing means.
- the method further comprises a step of recovering the separation fluid, preferably by depressurizing and / or heating the supernatant liquid phase.

- FIG. 1 schematically illustrates an embodiment of the method according to the invention.
- the bituminous sand for example conveyed by a conveyor from the mining site, and possibly cleared beforehand of the foreign matter which can be carried with it, is introduced in a capacity 10, and mixed within it at a distance of liquid carbon dioxide solution.
- This contact is effected in such a way that the carbon dioxide remains in the liquid phase under the temperature and pressure conditions at which the contacting step is carried out.
- the mixture is thus preferably carried out at a temperature between -15 ° C and -40 ° C and under moderate pressure, preferably between about 5 and 25 bar.
- the temperature applied during this contacting step is less than or equal to the glass transition temperature of the bitumen contained in the oil sand, considered to be -20 ° C. This makes it possible to weaken the cohesion of the mineral fraction / bitumen fraction by the cold system, the two fractions having very different coefficients of thermal expansion. Thus, separation and entrainment of bitumen are favored.
- the capacity 10 is preferably equipped with means 20 for contacting and mixing the bituminous sand and the liquid carbon dioxide, so as to facilitate the heat exchange, that is to say the heat transfer, and the transfer. of matter between the different fractions.
- a simple mobile stirring for example screw type, provides the minimum necessary mechanical energy.
- the efficiency of the heat exchange during this contacting step makes it possible to prevent the particles of bituminous sand from sticking to each other, and thus limits the formation of large agglomerates with a negative surface / volume ratio. entrainment of bitumen in liquid carbon dioxide.
- the use of liquid carbon dioxide as a separating fluid makes it possible to ensure a good coefficient of transfer of frigories to the bituminous sand. This coefficient is much higher than that which would be obtained with a cold gas. In addition, it allows operating at a low temperature and easy to control by simple pressure regulation.
- the capacitor 10 is a solid / liquid contactor with a continuous flow, such as a stirred tank, having for example a conical bottom, or a tank provided with an inner screw with or without a tube guide, which can also be a slanted axis screw.

- the settling tank is preferably provided with means for heating and depressurizing.
- the contacting and settling functions are provided by the same device, typically a mixer-settler well known in the art in the field of chemical engineering.
- a solid phase 40 is obtained at the bottom of the device surmounted by a supernatant liquid phase 70.
- the solid phase 40 mainly comprises sand and clays that are free of hydrocarbons.
- the substantially homogeneous liquid phase 70 comprises:
- bitumen fraction is then extracted from the liquid phase. This step is carried out in a flask fed by the liquid phase 70.
- the carbon dioxide is removed by decompression, which allows to recover the bitumen with a very good yield.
- a supplementary heating device is associated with the depressurization device.

- FIG. 2 Another embodiment, similar to that of FIG. 1, is shown in FIG. 2.
- a heterogeneous liquid phase 80 coexists with the solid phase 40 following the contacting step.
- This liquid phase 80 comprises a supernatant liquid phase 60 in which the bitumen is predominantly, while the remainder of the liquid phase 50 comprises hydrated liquid carbon dioxide.
- the supernatant liquid phase 60 is separated from the liquid 50, for example by mechanical skimming, in order to recover the bitumen, before depressurizing the lighter liquid phase 50, in order to recover the carbon dioxide at the same time. gaseous state.
- the carbon dioxide is preferably recycled: the carbon dioxide gas is collected after separation of the bitumen, returned to a purification section and then recompressed for reuse liquid at a maximum rate in the process.
- liquid carbon dioxide is used.
- any other separation fluid may be used insofar as it is present in the liquid state at the operating temperature and the operating pressure, the operating temperature being less than or equal to the transition temperature. vitreous bitumen.
- a separation fluid having one or more of the following properties will be chosen:

- the fluid is advantageously nontoxic
- the fluid is advantageously cheap, particularly if it comes from a natural source close to the oil sands resource;
- the fluid is advantageously recyclable during the process, minimizing the pressure drop of the operating loop of the process.
- Refrigerants such as freons or other types of fluorocarbon solvents, can be used as bitumen separation fluid in the bituminous sand.
- the process according to the invention advantageously comprises a small number of unit steps, avoiding any always delicate handling of dry powder solids and grinding at high mechanical intensity. Furthermore, the proposed method allows the implementation of simple mixer-settler type installations that are well known in the oil and mining industries, and are therefore more easily industrializable.
