Title: Separation of asphaltenes from bitumen and heavy oils using a metal salt catalyst
Inventor: OZUM BAKI
IPC: B01J27/10
Filed: 2003-05-16
Abstract: In the present invention a method for the separation of asphaltenes from, beat not limited to, oil sands bitumen, water slurry based oil sands extraction froth, heavy oils and heavy fractions of the refinery products by using the catalytic effect of metal salts, such as, belt not limited to aluminum chloride (AlCl3), zinc chloride (ZnCl2) and ferric chloride (FeCl3) as catalyst to promote intra molecular condensation between the asphaltene molecules similar to the Friedel-Crafts type alkylation reactions to condensate and flocculate asphaltenes for their rapid separation and precipitation. The precipitated asphaltenes are easily separated by density difference using gravitational or centrifuge settling apparatus. Separation of asphaltenes using the present invention could be applied to, but not limited to, asphaltene containing hydrocarbon fluid mixtures, oil sands bitumen, heavy oils and hydrocarbon-water emulsion systems containing solids such as sands, silt and clays.

IPC: A61M16/04
Filed: 2002-09-16
Abstract: L'invention concerne un appareil de ventilation d'un tube trachéal conçu pour évacuer de manière plus efficace les gaz expirés. Dans un mode de réalisation préféré, au moins un trou de fuite est crée sur les parois latérales d'une sonde d'intubation endotrachéale, les gaz expirés pouvant ainsi s'échapper de ladite sonde au-dessus du larynx, par exemple à l'arrière de la bouche (soit l'oropharynx). Chaque trou de fuite pourrait avantageusement avoir un diamètre se situant entre 0,5 et 4,0 mm. Dans un autre mode de réalisation, un tube est fixé à un trou de fuite proportionnellement plus grand (par exemple jusqu'à 8,0 mm), les gaz expirés pouvant ainsi être dirigés hors du trou de fuite vers un emplacement spécifique, par exemple hors de la bouche. Dans le cas d'une ventilation mécaniquement commandée, on peut appliquer une pression de fin d'expiration positive audit tube, ce qui facilite le processus d'exhalation de façon mécanique. Dans chacun de ces modes de réalisation, on préfère, sans que cela soit une exigence, que la sonde d'intubation endotrachéale soit un tube à deux étages, aux parois ultra-minces, afin de mieux aider à réduire la résistance au débit d'oxygène/air.
