Publication number: 20100037654Abstract: A hydrocarbon stream (30), such as natural gas, is commonly cooled together with a first refrigerant stream (140), against an evaporating refrigerant (24) in a series of one or more consecutively arranged common heat exchangers (2), which comprises a first common heat exchanger, upstream of which first common heat exchanger the hydrocarbon stream (10) and the first refrigerant stream (130) are not commonly cooled (4, 3). The hydrocarbon stream to be cooled is fed into the first common heat exchanger at a hydrocarbon feeding temperature, while the first refrigerant stream is fed into the first common heat exchanger at a refrigerant feeding temperature. The temperature difference between the hydrocarbon feeding temperature and the refrigerant feeding temperature is lower than 60-C.Type: ApplicationFiled: October 11, 2007Publication date: February 18, 2010Inventors: Mark Antonius Kevenaar, Johan Jan Barend Pek, Chun Kit Poh

Publication number: 20100037655Abstract: A method for recovering hydrogen from a gas stream is presented. This method includes introducing a feed gas stream comprising hydrogen and methane to a first cold box, thereby producing a first hydrogen-enriched stream, and a first methane-enriched stream; then introducing the first hydrogen-enriched stream to a first feed compressor, thereby producing a compressed first hydrogen-enriched stream. The method includes introducing the compressed first hydrogen-enriched stream to a second cold box, thereby producing a second hydrogen-enriched stream, and a second methane-enriched stream; then introducing the second hydrogen-enriched stream to a second feed compressor, thereby producing a compressed second hydrogen-enriched stream. The method includes introducing the compressed second hydrogen-enriched stream to a third cold box, thereby producing a third hydrogen-enriched stream, and a third methane-enriched stream.Type: ApplicationFiled: December 9, 2008Publication date: February 18, 2010Applicant: Air Liquide Process and Construction Inc.Inventor: Bhadra S.

Publication number: 20100037656Abstract: A method of separating air in which a superheated air stream is introduced into a mass transfer contacting zone associated with a higher pressure column of an air separation unit. Krypton and xenon is washed from a superheated air stream introduced into the mass transfer contacting zone, thereby to form a krypton and xenon-rich liquid. The krypton and xenon-rich liquid is stripped within a stripping column to produce a krypton-xenon-rich bottoms liquid. A krypton-xenon-rich stream composed of the krypton-xenon-rich bottoms liquid from the stripping column is produced for purposes of further refinement.Type: ApplicationFiled: August 14, 2008Publication date: February 18, 2010Inventors: Neil Mark Prosser, John Bernard Saunders

Publication number: 20100037658Abstract: A vehicular upholstery fabric is made from a raw tricot fabric which is knitted by using a PPT-multifilament yarn whose single fiber fineness is about 0.5˜6.0 dtex and whose total fineness is about 30˜180 dtex for the ground yarn and the pile yarn. The raw tricot fabric has been transformed into a napped tricot pile fabric by raising the sinker loop of the pile yarn of the raw tricot fabric to form fluffs which are then sheared to form cut piles. A PPT-bulky multifilament yarn is used for the ground yarn. A PPT-non-bulky texturized multifilament yarn or a PPT-bulky texturized multifilament yarn is used for the pile yarn.Type: ApplicationFiled: May 9, 2007Publication date: February 18, 2010Applicant: Honda Motor Co., Ltd.Inventors: Daisuke Susa, Hidehito Fukumoto, Kazuki Kitagawa, Tomohiro Nagao

Publication number: 20100037660Abstract: In a washing machine, vibration of a cabinet vibrated by a tub is offset by a dynamic vibration absorber. Therefore, vibration of the cabinet is reduced and thus noise of the washing machine is reduced.Type: ApplicationFiled: November 9, 2007Publication date: February 18, 2010Applicant: LG Electronics Inc.Inventor: Kyung Seop Hong
