The invention relates to a continuous process for treatment of feed in the form of a heavy hydrocarbon-water dispersion or dispersions. The feed (7) is diluted with a hydrocarbon solvent (8) and contacted in a contactor (9) with a water stream (11). A product stream (10) containing bitumen oils and a discard stream (12) comprising water and solids are separately removed from the contactor (9). |

| 42 | Carbonaceous solids cleaning process | EP80302329.0 | 1980-07-09 | EP0022659A1 | 1981-01-21 | Guerre, Robert Peter |
t A fraction, for example a 75 to 10 mm fraction, of carbonaceous solids having components of differing densities, such as coal, is physically cleaned by gravimetric separation in a washing tank (12) containing washing medium of s.g. 1.5 to 1.9. The resultant low density fraction, which contains relatively small amounts of inorganic materials, is passed to a second gravimetric separation stage (18) containing washing medium of s.g. 1.3 to 1.5. Low density, clean solids are removed and recovered (20). High density material is passed (22) to a crusher (24) and particulate material of 25 to 6 mm is fed from the crusher (24) to a vibrating screen (28). Fine particles from the screen (28) are passed (30) to a froth separator and clean solids recovered. Coarse particles from the screen (28) are gravimetrically separated in a cleaning cyclone (34) containing washing medium of s.g. 1.5 to 1.9. Low density clean solids are recovered (38, 20). |

A process for refining sand for use as frac sand comprising the steps of passing the sand through a first fines separation stage to remove fine particles of contaminant from the sand, reducing the water content of the sand to less than 20%, passing the sand into an attrition scrubber unit containing moving blades to delaminate clay and other contaminants from the sand grains, passing the sand from the attrition scrubber unit through a second fines separation stage to separate fine contaminants from the sand and dewatering the resulting sand product in a further dewatering stage.

| 44 | PROCESSING ASPHALTENE-CONTAINING TAILINGS | EP06737434.8 | 2006-03-07 | EP2040848A1 | 2009-04-01 | DUYVESTEYN, Willem, P., C.; KIFT, Julian; MORLEY, Raymond. L. |
| Embodiments of a method and a system for recovering energy, materials or both from asphaltene-containing tailings are disclosed. The asphaltene-containing tailings can be generated, for example, from a process for recovering hydrocarbons from oil sand. Embodiments of the method can include a flotation separation and a hydrophobic agglomeration separation. Flotation can be used to separate the asphaltene-containing tailings into an asphaltene-rich froth and an asphaltene-depleted aqueous phase. The asphaltene-rich froth, or an asphaltene-rich slurry formed from the asphaltene-rich froth, then can be separated into a heavy mineral concentrate and a light tailings. Hydrophobic agglomeration can be used to recover an asphaltene concentrate from the light tailings. Another flotation separation can be included to remove sulfur-containing minerals from the heavy mineral concentrate. Oxygen-containing minerals also can be recovered from the heavy mineral concentrate. Water removed by the various separation steps can be recycled and its heat energy recovered. | ||||||

| Sand is discharged from a vessel at an elevated pressure and is delivered at a lower pressure. The sand is subjected to the following steps before delivery: I) dilution with a dilution fluid, ii) passage through at least one pressure reducing cyclone, the dilution being such that flashing is reduced, and iii) delivery as a slurry at the delivery pressure. This results in less wear of the components. | ||||||
| 46 | A METHOD FOR THE EXTRACTION OF OIL BY MICROEMULSIFICATION | EP00911030.5 | 2000-03-13 | EP1165199B1 | 2005-08-03 | Oldfield, Christopher |
| The invention provides a method for the removal of oil from oil-contaminated solid wastes such as drilling muds, of fractions thereof, by mixing the preparation with an aqueous surfactant preparation such that the oil is extracted as an oil-in-water (O/W) microemulsion. The microemulsion and solids phases can be separated by a suitable technique such as centrifugation; residual O/W microemulsion can be removed by an aqueous rinse. The oil can be recovered from the O/W micro emulsion by suitable techniques including, but not limited to, temperature-induced phase-separation. | ||||||

| Friable solid material contaminated by oxidizable hydrocarbons such as petrochemicals is delivered into a system wherein the material is subjected to a series of physical and chemical reactions to separate the contaminants from the solid material. The system can receive solid material, separate coarse from fine material, and suspend the fine material in an aqueous medium. The aqueous suspension is subjected to temperature adjustment and the addition of an oxidizing agent, preferably hydrogen peroxide. The suspension is agitated for a period of time to allow the hydrocarbons to be oxidized. The gaseous oxidation products are stripped and separated from the residual solid material. The aqueous suspension of solid material and diluent are physically separated and the solid material may be returned to its point of origin after treatment. The process and apparatus for carrying out the process are preferably applied to soils containing hydrocarbon pollutants. | ||||||

| The invention relates to a process for cleaning granular materials like mill scale and oil-contaminated minerals of attached fatty substances, especially oil, in which, for the purposes of surface cleaning, the materials are subjected to a solid-body mechanical stress (attrition 2) and conditioning (4) with the addition of liquid or washed with a detergent possibly containing surface-active reagents (tensides) and dispersants in a flotation plant (5). According to the invention, it is proposed that the materials be treated in a single or multi-stage cyclone (6, 16) between attrition (2) and flotation (5), preferably after conditioning (4) for partial separation into cleaned material (7, 17) and an oil-enriched phase (14, 19). Flat-bed cyclones (6, 16) are to be used, in particular. | ||||||

| Un procédé servant à éliminer les hydrocarbures contenus dans des matières solides contaminées consiste à exposer les solides, dans une chambre d'extraction (12), à un solvant agissant sur l'huile, tel que du toluène ou toute autre fraction d'essence stabilisée. Le solvant dissout alors l'huile, et les solides peuvent être séparés du solvant dans lequel l'huile a été dissoute. Selon une variante, les solides et le solvant peuvent être transformés en une boue dans une cuve agitatrice, puis être pompés dans une centrifugeuse de décantation à bol plein (26) à partir de laquelle les solides sont alimentés dans un dispositif de séchage (18). | ||||||

Es wird eine Vorrichtung beschrieben, mit welcher Schleifrückstände, d.h. Schleifschlamm der bei der Bearbeitung ferromagnetischer Werkstoffe entsteht, aufbereitet werden kann. Solche Schleifrückstände sind insbesondere noch mit Öl und Wasser behaftet und werden in dieser Vorrichtung in einen Trennbehälter (14) gegeben, welcher eine waschaktive Substanz bzw. Waschlösung (51) enthält. In diesem Trennbehälter (14) wird unter Mischen und Umrühren das an den Schleifrückständen anhaftende Öl gelöst. Anschließend wird in einer ersten Phase an den Behälterwänden mit Permanentmagneten (17) Magnetfelder erzeugt, in denen sich die ferromagnetischen Bestandteile der Rückstände anlagern. Die weiteren Bestandteile können nunmehr durch ein Filter (18) geleitet werden und dort aus der Waschlösung herausgefiltert werden. Nachdem diese Bestandteile entfernt sind, wird das Magnetfeld abgeschaltet. Die ferromagnetische Bestandteile gelangen nunmehr wieder in die Waschlösung und werden mit der Waschlösung in dieses Filter (18) oder ein weiteres Filter (19) geleitet, dort herausgefiltert und getrocknet. Die Waschlösung wird nachfolgend einem Behälter (25) zugeführt; in diesem erfolgt eine Rückgewinnung des aus den Rückständen entfernten Öls. |
