Publication number: 20190063829Abstract: An annular divided wall column for the cryogenic rectification of air or constituents of air is provided. The annular divided wall column includes a first annular column wall and a second annular column wall disposed within the first annular column wall to define an annulus column region and an interior core column region. The present annular divided wall column further includes structured packing elements disposed within at least the annulus column region as well as a ring-shaped cantilevered collector; and a ring-shaped distributor disposed in the annulus column region above or below the plurality of structured packing elements. The thermal expansion and contraction of the second annular column wall in a radial direction and in an axial direction is independent of the thermal expansion and contraction of the first annular column wall in the radial and axial directions.Type: ApplicationFiled: July 23, 2018Publication date: February 28, 2019Inventors: Kevin J.

Patent number: 9692347Abstract: Systems and methods involve controlling a variable-speed blower in a heating, ventilating, and air conditioning (HVAC) system to ensure the setting of a blower-proving switch to confirm airflow in a building. In one instance, a method involves ramping up the variable-speed blower so that the associated static pressure reaches a making point pressure of the blower-proving switch and then reducing the power to a desired power level. The method may also include maintaining the power level above a breaking point pressure. Other systems and methods are presented.Type: GrantFiled: June 13, 2014Date of Patent: June 27, 2017Assignee: Lennox Industries Inc.Inventors: Der-Kai Hung, Harold Gene Havard, Jr., Rosa Maria Leal, Steven C.

Patent number: 9457291Abstract: A combined collector and distributor for a distillation column that includes a collector portion connected to a distributor portion. The distributor portion includes a channel-like distributor to distribute liquid into an underlying packing. The collector portion has spaced rows of collection elements that cover the open spaces and distribution elements of the distributor portion and one or more rectangular sumps into which descending liquid drains from the collection elements. The liquid in turn drains from the rectangular sump or sumps into a pre-distribution box located within a header of the distributor portion. The collection elements that cover the open spaces are set at higher positions than the collection elements covering the distribution elements to form chimneys to allow the ascending vapor to escape from the collector portion.Type: GrantFiled: March 10, 2015Date of Patent: October 4, 2016Assignee: PRAXAIR TECHNOLOGY, INC.Inventors: Steven C. Brown, John P. Ricotta, Andrew P. Dybdahl, Guang X. Chen

Publication number: 20160061541Abstract: The present invention provides a vapor-liquid contact device for use in a distillation column and method incorporating the use of such a vapor-liquid contact device. The vapor-liquid contact device has arrays of elongated strips to support a falling film of a liquid and contact of a vapor with the film. The strips are supported in a structure having top and bottom sections connected to opposite ends of the strips. The top sections have apertures in registry with the strips so that liquid distributed to the top section seeps out of the apertures to initiate formation of the falling film. Openings are provided at the top and bottom sections, so that a vapor is able to pass through the support structure to contact the falling film to effect contact between the liquid and the vapor. Liquid distributors are associated with the top section to distribute the liquid to the apertures.Type: ApplicationFiled: August 24, 2015Publication date: March 3, 2016Inventors: Guang X. Chen, Steven C. Brown, Andrew P. Dybdahl, Kirk F. Larson, John P. Ricotta
