Patent number: 7029638Abstract: A device that is placed in a vessel for carrying out separate injection (1,6) of two fluids in two different physical states, or which are not miscible, and for homogeneous distribution of at least one of the two fluids in the vessel downstream of said device. The first fluid is injected (6) into the vessel at least one point level with said device, said device being characterized in that it contains a chamber (5) pierced by orifices (7, 8) for the passage of a first fluid. Said chamber (5) is also imperviously traversed by tubes (4) or conduits with a free end acting as a passage through said chamber for the second fluid.Type: GrantFiled: December 21, 2001Date of Patent: April 18, 2006Assignee: Institut Francais de PetroleInventors: Christophe Boyer, Vincent Coupard, Gilles Munier

Patent number: 7021608Abstract: An ultra low flow liquid distributor generates a very thin yet continuous liquid film over the entire width of a transfer surface. The ultra low flow liquid distributor includes a liquid supply system starting from a common main supply, which is split by repetitive bifurcations into a multitude of liquid sub-mains, until eventually each liquid supply sub-main feeds into one of the many liquid outlet openings. In this the liquid outlet openings are arranged above the liquid supply system, which automatically ensures self-priming.Type: GrantFiled: August 23, 2002Date of Patent: April 4, 2006Inventors: Eberhard Lävemann, Matthias Peltzer

Patent number: 6969495Abstract: For use in a separation column, a mat element or a beam element has at least: an upper part 2; at least one distributor-collector part (3) having one or more secondary orifices (7i) and at least one main orifice (6), whereby the passage sections of orifices (8) and (7i) are different; and a lower part (4). The distributor-collector part or parts (3) arranged between the upper part (2) and the lower part (4). A sealing element (5a) arranged between the distributor-collector part (3) and the upper part (2), and a sealing element (5b) arranged between the distributor-collector part (3) and the lower part (4). A separation element (8) arranged at distributor-collector part (3), thus delimiting two spaces (3a, 3b) for circulation of fluids.Type: GrantFiled: June 9, 2000Date of Patent: November 29, 2005Assignee: Institut Francais du PetroleInventors: Gérard Hotier, Pierre Renard, Xavier Decoodt

Patent number: 6952949Abstract: An arrangement for coupling microwave energy into a plasma CVD coating chamber (3) disposed in a cavity resonator (1) has a microwave feed (11) and a microwave waveguide (9, 1). So that a plastic container of a size and configuration which differ to a certain degree can be effectively coated in its interior, it is provided that the arrangement is of a substantially cylindrical structure, such that provided at the rear end is a first coaxial waveguide (in the region a) with an internal conductor in the form of an antenna (12), an approximately cylindrical waveguide (in the region b) follows in the centre of the arrangement and provided at the front end (in the region c) is a second coaxial waveguide (1) with internal conductor (13), wherein gas can be introduced through a gas feed tube (13) into the second coaxial waveguide (in the region c), which gas can be activated into the plasma state by the coupled-in microwave energy, and wherein a TM-mode is produced by the antenna (12) in the plasma region (1, c).Type: GrantFiled: December 15, 2000Date of Patent: October 11, 2005Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Rodney Moore, Wolf Essers

Patent number: 6889961Abstract: Anti-swirl baffles are provided in a mass transfer column to reduce the swirling motion of a vapor or mixed phase feed stream introduced into the column. The column is of the type having an upper region of a preselected diameter, a lower region of reduced diameter, and an intermediate transition region that has a diameter that transitions from the preselected diameter of the upper region to the reduced diameter of the lower region. The column includes a vapor or mixed phase feed nozzle and a feed device such as a vapor horn located at least partially within the upper region for delivering the vapor or mixed phase feed stream into the column. The anti-swirl baffles are positioned in the intermediate transition region of the column to disrupt the swirling motion of the vapor or mixed phase feed stream as portions of it descend from the feed device into the transition region of the column.Type: GrantFiled: April 3, 2003Date of Patent: May 10, 2005Assignee: Koch-Glitsch, LPInventors: Dana G. Laird, Brian D. Albert, Carol A. Schnepper, Christoph Ender

Patent number: 6877725Abstract: This invention is directed to a cyclonic vapor/liquid contacting device and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall, where it exits through slots in the wall. A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone. This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone.Type: GrantFiled: July 1, 2003Date of Patent: April 12, 2005Assignee: Mobil Oil CorporationInventors: John Scott Buchanan, Berne K.

Patent number: 6830099Abstract: An improved two-phase refrigerant distributor for use in a falling film evaporator in a refrigeration chiller system defines apertures in its undersurface from which serrated collars depend. The serrations cooperate to define locations below the undersurface of the distributor to which liquid refrigerant is drawn prior to exiting the distributor. As a result, the hang-up and/or travel of liquid refrigerant on the distributor undersurface is reduced or eliminated.Type: GrantFiled: December 13, 2002Date of Patent: December 14, 2004Assignee: American Standard International Inc.Inventor: Shane A. Moeykens
