Patent CA-2390657-C (CA)
Inventor: KOSTELNIK ROBERT J
IPC: C09C1/36

Abstract: L'invention concerne un traitement destiné à rendre hydrophobes des particules d'oxyde inorganique, tel qu'un pigment TiO2, en prédispersant un organohalosilane réagissant de manière adéquate dans un milieu aqueux par l'intermédiaire de moyens de mélange intensif (notamment un émulsionneur muni d'un rotor-stator ou un mélangeur statique en ligne) de manière à obtenir une dispersion réactive. Lorsque cette dernière est combinée, sous l'effet d'une agitation suffisante, à des particules d'oxyde inorganique, telles qu'un pigment TiO2, on peut obtenir un oxyde inorganique hydrophobe. Les oxydes ainsi obtenus présentent de bonnes propriétés mécaniques, notamment leur capacité de dispersion dans les substances non polaires (les plastiques, par exemple), et n'affectent pas les propriétés physiques de la substance non polaire pigmentée, telle que la résistance à la formation de porosités des thermoplastiques.

Abstract: An oil supply system supplies oil under pressure to a bearing enclosure during normal positive gravity conditions as well as negative and zero gravity conditions. A closed oil storage tank containing a volume of oil below a gas filled headspace with primary drain in a bottom portion normally supplies a pressure pump which passes a pressure control valve before entering an inlet of the enclosure. In negative gravity or zero gravity conditions oil is absent from the tank bottom and the primary pressure pump is starved of oil. The invention solves this problem with an auxiliary tank outlet disposed above the bottom drain (at the top and/or sides of the tank) and the oil-air separator separates the air before pumping the oil under pressure to the bearing or journal enclosure past a directional switch.

Title: Viscoelastic compositions
Inventor: ZHOU JIAN
IPC: C09K23/18
Filed: 2002-02-13
Granted: 2010-04-06
Abstract: The present invention provides aqueous viscoelastic compositions comprising a cleavable surfactant and possibly also an electrolyte. The cleavable surfactants useful in the present invention comprise at least one weak chemical bond, which is capable of being broken under appropriate conditions, to produce oil soluble and water soluble products typically having no interfacial properties and surface activity compared with the original surfactant molecule. Further, the rheological properties of the aqueous viscolelastic composition are usually altered upon cleavage of the cleavable surfactant generally resulting in the elimination of the viscofying, viscoelastic and surfactant properties of the composition. Aqueous viscoelastic compositions in accordance with the present invention are suitable for use in oil-field applications, particularly for hydraulic fracturing of subterranean formations. Thus, the present invention also relates to a wellbore service fluid and a method of fracturing a subterranean formation. The present invention also concerns novel cleavable surfactants.

Granted: 2011-02-15
Abstract: The methods and apparatus for heating a catalyst bed (410) for start-up and for providing heat to a catalyst bed (410) during transient operation to maintain desired reaction temperatures. An electrical heating element (400) may directly or indirectly heat the catalyst. The direct heating of catalyst is achieved by having direct contact of the heater element (400) with the catalyst. Indirect heating is achieved by direct heating of a fluid, such as a process flow, which in turn flows through the catalyst, thereby transferring heat to the catalyst. Additionally, indirect heating may be achieved by placing the heating element (400) within a sheath that is then either in direct contact with the catalyst or fluid that flows through the catalyst. By these means, catalyst of many forms may employ this catalyst heater (400), including pellets, extrudates, spheres, and monoliths. The catalyst heater (400) in accordance with this invention can be made of any resistive wire, cartridges, or rods that may be coupled to a power source to provide the energy to produce the heat.
