Patent number: 8216343Abstract: A radial flow reactor vessel is disclosed for use in gas purification, separation or reaction processes and most suitably used in prepurification processes. The reactor has internal baskets for confining a bed of active material. The baskets are rigidly supported at both the top and bottom ends of the reactor and have walls that are axially flexible and radially rigid. The vessel has multiple movable support columns designed to facilitate pre-stressing of the baskets to offset axial compressive loads induced from thermal cycling.Type: GrantFiled: February 25, 2010Date of Patent: July 10, 2012Assignee: Praxair Technology, Inc.Inventors: Mark William Ackley, Cem E. Celik, Jeffert John Nowobilski, James Stanley Schneider

Patent number: 7713333Abstract: The present invention relates generally to adsorbents for use in pressure swing adsorption (PSA) prepurification processes. The invention more particularly relates to the design of adsorbent zones to be used in PSA prepurification processes that are expected to provide for extensions in PSA cycle time, thereby reducing blowdown loss and operating costs associated with the process. One particular embodiment of the present invention includes a first adsorption zone containing activated alumina and a second adsorption zone of an alumina-zeolite mixture or composite adsorbent in which the volume of the first zone does not exceed 50% of the total volume of the first and second zone.Type: GrantFiled: December 20, 2006Date of Patent: May 11, 2010Assignee: Praxair Technology, Inc.Inventors: Salil Uday Rege, Mark William Ackley, Jeffert John Nowobilski

Patent number: 7632337Abstract: The present invention relates to cryogenic air separation processes and systems that employ a pressure swing adsorption (PSA) prepurification process. It is advantageous to operate the PSA process at a pressure comparable to or below the operating pressure of the highest pressure column in the cryogenic separation unit. Following PSA prepurification, the air can be split into at least two fractions, with at least a portion of the air being directed to the cryogenic separation unit and at least a portion of the remaining air being further pressurized in at least one stage of compression.Type: GrantFiled: June 30, 2006Date of Patent: December 15, 2009Assignee: Praxair Technology, Inc.Inventors: Henry Edward Howard, Jeffert John Nowobilski

Patent number: 7527670Abstract: This invention comprises an adsorption process for the removal of at least N2O from a feed gas stream that also contains nitrogen and possibly CO2 and water. In the process the feed stream is passed over adsorbents to remove impurities such as CO2 and water, then over an additional adsorbent having a high N2O/N2 separation factor. In a preferred mode the invention is an air prepurification process for the removal of impurities from air prior to cryogenic separation of air. An apparatus for operating the process is also disclosed.Type: GrantFiled: December 19, 2002Date of Patent: May 5, 2009Assignee: Praxair Technology, Inc.Inventors: Mark William Ackley, Himanshu Saxena, Gregory William Henzler, Jeffert John Nowobilski

Patent number: 7264651Abstract: For PSA or TSA prepurifiers, the temperature rise on adsorption is particularly troublesome when the temperature rise reaches the end of the bed at the end of the adsorption step. This results in an increase in the CO2 and N2O concentration at the end of the cycle. Addition of a regenerator in the middle of the adsorption layer will reduce the temperature rise at the end of the bed and thus enhance the performance of the bed.Type: GrantFiled: July 2, 2004Date of Patent: September 4, 2007Assignee: Praxair Technology, Inc.Inventors: Gregory William Henzler, Jeffert John Nowobilski, Mark William Ackley, Michael George Noakes

Patent number: 7122073Abstract: A low void pressure swing adsorption system wherein flow movement and pressure pulse are influenced from the same source comprised of at least one hermetically sealed vessel containing an adsorbent bed with an inlet coupled to the adsorbent bed by way of an inlet header and an outlet coupled to the adsorbent bed by way of an outlet header. Void volume of the inlet and outlet headers can be limited to less than 20% of the adsorbent bed volume, preferably to less than 10%, and most preferably to less than 5%, by mounting high pressure source(s) and/or low pressure sink(s) proximate to, or nearly proximate to, the adsorbent bed/vessel. Low void volumes and reduced cycle times may be achieved in all bed configurations, including flat header beds, segmented beds, and vertical beds. Radial beds may be configured so that the void volume of the inlet and outlet headers is less than 50% of the volume of the radial adsorbent bed, preferably to less than 20%, and most preferably to less than 10%.Type: GrantFiled: September 18, 2000Date of Patent: October 17, 2006Assignee: Praxair Technology, Inc.Inventors: Frank Notaro, Alan Barnard Stewart, Jeffert John Nowobilski, Guoming Zhong, Arun Acharya

Patent number: 6663341Abstract: A process fluid recycle system for compressor assemblies to recycle process fluid vapor flowing from one or more compressors to gear case(s) through shaft seal(s). The flowing process fluid is recycled back to the low pressure inlet of the compressor assembly by way of a recycle conduit. Coalescing filters are provided to separate oil mist from the process fluid vapor. Oil vapor and water vapor can also be removed, where necessary, by suitable oil and water vapor traps. During startup and shutdown or other times when low pressure transients occur that could cause a back flow of gear oil from the gear case into the compressor(s) by way of the shaft seal(s), an anti-back flow compressor is operated to ensure that the pressure within the gear case will be less than within the compressor.Type: GrantFiled: February 19, 2002Date of Patent: December 16, 2003Assignee: Praxair Technology, Inc.Inventors: Alfred Peter Evans, Neno Todorov Nenov, Gregory William Henzler, Jeffert John Nowobilski, Robert Leroy Baker

Patent number: 6582185Abstract: A sealing system to prevent loss of a process fluid from a device having a device opening and a rotating member operable for rotational movement within the device opening. A rotary shaft seal such as a labyrinth seal, seals the rotating member in the device opening to inhibit leakage of process fluid. A chamber is connected to the device to recover leakage of the process fluid that leaks from the rotary shaft seal. A barrier seal is connected to the chamber to inject a barrier fluid under pressure to prevent the escape of process fluid from the chamber. The chamber discharges a mixture of barrier and process fluid to a filter, such as a coalescing filter, to separate the barrier fluid from the process fluid. Barrier fluid vapor and water vapor traps can also be used for purification purposes. The barrier fluid is recovered and recycled back to the barrier seal. The process fluid is returned to the device.Type: GrantFiled: September 14, 2001Date of Patent: June 24, 2003Assignee: Praxair Technology, Inc.Inventors: Adam Kenneth Lippert, Scott Alan Spriggs, Gregory William Henzler, Jeffert John Nowobilski, Robert Leroy Baker
