Publication number: 20030159581Abstract: A method and system for sea-based handling/treatment of fluid hydrocarbons (oil) with associated gas comprise a first separation step in a high-pressure separator (18) installed on the sea bed, from which is output an oil flow containing an essentially predefined percentage of residual gas. The oil containing residual gas is carried through a riser (22) up to a surface vessel/production ship (12), where it is subjected to a second separation step in a second separator (24) incorporated in a low-pressure surface plant on board the vessel (12), this separated residual gas being used as fuel for direct/indirect generation of electric power for the operation of the underwater and above-water sections of the system. Water and gas produced in the first separation step is returned to a suitable reservoir by the use of a multiphase pump.Type: ApplicationFiled: April 22, 2003Publication date: August 28, 2003Inventors: Morten Sanderford, Bernt Helge Torkildsen, Jens Grendstad, Egil Tveit, Olav Inderberg

Publication number: 20030159582Abstract: An apparatus and method are provided for deaerating liquid crystal contained in at least one liquid crystal container. The apparatus includes a chamber, a holder, a displacement mechanism, a vacuum system and a gas supply. The chamber has an opening to provide access to an interior of the chamber and a cover to seal the opening. The holder is disposed in the chamber to hold the liquid crystal container having the liquid crystal while the displacement mechanism displaces the at least one container. Here, the vacuum system creates a vacuum state in the chamber during deaeration, and the gas supply restores the chamber to atmospheric pressure.Type: ApplicationFiled: April 24, 2002Publication date: August 28, 2003Applicant: LG. Philips LCD Co., Ltd.Inventors: Hyug Jin Kweon, Hae Joon Son

Publication number: 20030159584Abstract: The invention relates to a dust filter, with at least one dust filter sleeve (1), closed at the bottom end thereof, impinged on from the outside by the dust-containing gases, comprising at least one electrofilter (3), with at least one collecting electrode (4). According to the invention, the filter effect may be improved, by means of increasing the degree of dust separation, whereby the at least one emission electrode (2) is arranged behind the at least one collecting electrode (4), as viewed from the filter sleeve (1). The filter sleeve (1) and associated support cages (7). are preferably electrically isolated. During cleaning of the filter sleeves (1) the ionised dust particles (5) fall for the greater part on the directly adjacent collecting electrode (4).Type: ApplicationFiled: April 29, 2003Publication date: August 28, 2003Inventor: Alois Scheuch

Publication number: 20030159586Abstract: An adsorption bed arrangement includes a plurality of adsorption elements, a housing, and a gasket member. Each of the adsorption elements has a first adsorptive media and a second adsorptive media contained within a respective element. The first and second adsorptive medias remove different contaminants from the incoming air stream. For example, the first adsorptive media removes acidic contaminants and the second adsorptive media removes basic contaminants. Each of the adsorption elements is selectively openable to provide access to the adsorptive medias. The housing defines an interior, a plurality of inlet openings, and a plurality of outlet openings. The adsorption elements are positioned within the housing interior and the housing is selectively openable to provide access to the adsorption elements. The gasket member is between the housing and the adsorption elements.Type: ApplicationFiled: March 13, 2003Publication date: August 28, 2003Applicant: Donaldson Company, Inc.Inventors: Kevin J. Seguin, Paul Peterson, Kristine M. Graham

Publication number: 20030159587Abstract: A low cost combined air cleaner and resonator includes two housing members which snap together. An air filter is captured between the two members. A first of the members receives the air filter, and the second of the two members has an enlarged plenum to provide a resonator function. The combined air cleaner and resonator thus provides a low cost way of achieving both functions in a system for supplying clean air to a vehicle engine.Type: ApplicationFiled: February 13, 2003Publication date: August 28, 2003Applicant: Siemens VDO Automotive, Inc.Inventors: Mark Letourneau, Frances Warren, Roderic Cole
