Patent number: 9333458Abstract: A gas separation module includes at least one inlet port, a plurality of outlet ports, and a plurality of hollow fiber membranes. Individual fibers have a feed end and a product end with a retentate interior side and a permeate exterior side. The module includes a feed tubesheet within the shell segregating the at least one inlet port and the permeate side of the fibers. The feed tubesheet includes a matrix and at least one segment joint. The segment joint separates segments of the feed tubesheet from one another. A formation method includes positioning a hollow fiber membrane material in association with at least one tubesheet segment joint and applying a matrix. The method includes forming a feed tubesheet from cured matrix and the segment joint and forming a plurality of hollow fiber membranes from the fiber material. The segment joint separates segments of the feed tubesheet from one another.Type: GrantFiled: December 7, 2015Date of Patent: May 10, 2016Assignee: THE BOEING COMPANYInventor: Tuan Q. Cao

Patent number: 8764869Abstract: The present invention relates to a separator and more specifically, but not exclusively, to a centrifugal separator for the cleaning of a gaseous fluid. A centrifugal separator is provided as comprising a housing defining an inner space, and a rotor assembly for imparting a rotary motion onto a mixture of substances to be separated. The rotor assembly is located in said inner space and is rotatable about an axis relative to the housing. The rotor assembly comprises an inlet for receiving said mixture of substances, an outlet from which said substances are ejected from the rotor assembly during use, and a flow path for providing fluid communication between the inlet and outlet, wherein the outlet is positioned more radially outward from said axis than the inlet.Type: GrantFiled: January 10, 2012Date of Patent: July 1, 2014Assignee: Alfa Laval Corporate ABInventor: Thomas Eliasson

Publication number: 20110265652Abstract: A dust removal method using baghouse filter to process raw syngas from fluidized bed coal gasifier, wherein temperature in the baghouse (300) is maintained at 180° C.-250° C., pressure difference between the gas inlet (130) of the baghouse (300) and the gas outlet (110) of the baghouse (300) is controlled at 1000-5000 Pa, the raw syngas from the fluidized bed coal gasifier enters the gas inlet under the pressure of 0.2-3.0 Mpa. The present method effectively solves the technical problems of condensation and baghouse block due to high steam and ash content in the raw syngas from the fluidized bed coal gasifier and the present method is also applicable to remove dusts from the raw syngas produced by the fluidized bed coal gasifier under the conditions of high water-gas ratio (the water-gas ratio is up to 37%), high dust content (15-100 g/Nm3 dusts) and 0.2-3.0 Mpa pressure. The present invention also discloses a baghouse dust collector and a dense phase pneumatic conveying apparatus for the method.Type: ApplicationFiled: May 26, 2009Publication date: November 3, 2011Applicant: Synthesis Engery Systems, IncInventors: Minghai Gu, Songliang Sun, Guangliang Luo

Publication number: 20110259190Abstract: A system includes a particulate matter (PM) filter that includes an upstream end for receiving exhaust gas and a downstream end. A zoned resistive heater is arranged spaced from said upstream end and includes N zones, where N is an integer greater than one, wherein each of the N zones includes M sub-zones, where M is an integer greater than or equal to one, and wherein the zoned heater includes an electrically insulating material. A control module selectively activates at least a selected one of the N zones to initiate regeneration in downstream portions of the PM filter from the one of the N zones and deactivates non-selected ones of the N zones.Type: ApplicationFiled: November 2, 2007Publication date: October 27, 2011Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Eugene V. Gonze, Michael J. Paratore, JR., Kevin W. Kirby, Amanda Phelps
