Patent number: 11946599Abstract: An apparatus for hydrogen dispensing can be configured to generate a display to be output visually to a customer that may use a dispenser to fill a fuel tank with hydrogen fuel. The display can include a graphical user interface or other interface that can show the customer information about the dispensing of fuel that is being provided to the user. This displayed information can include information to indicate an estimated time remaining to fully fill a vehicle's fuel tank so the customer can have visual and/or audible indications for how much longer the customer may have to wait to have the vehicle's fuel tank filled for continued use of the dispenser. This can improve the customer's experience at the fueling station. For instance, embodiments can allow the customer to more effectively use the fueling station and manage his or her time at the fueling station.Type: GrantFiled: June 8, 2022Date of Patent: April 2, 2024Assignee: AIR PRODUCTS AND CHEMICALS, INC.Inventor: Joseph P. Cohen

Publication number: 20230287875Abstract: An apparatus and process for cooling down a liquid hydrogen or other cryogenic fluid pump can be configured to allow for a quick startup that also helps minimize hydrogen losses. Some embodiments can utilize a blow-by circuit configured and arranged to support the cryogenic cooldown operation for the pump that can minimize hydrogen loss while allowing substantially improved pump startup times. Some embodiments can utilize at least one temperature sensor to monitor temperature and an adjustable control valve that can facilitate the flow of the fluid utilized to perform the cooldown of the pump.Type: ApplicationFiled: March 8, 2022Publication date: September 14, 2023Applicant: Air Products and Chemicals, Inc.Inventors: Steven W. Hoffman, David Jonathan Chalk, Joseph P. Cohen

Publication number: 20230279996Abstract: A method and system for forming a compressed gas and dispensing it to a compressed gas receiver. The compressed gas is formed from a process fluid provided at a cryogenic temperature. The forming includes pressurizing the process fluid, feeding the pressurized process fluid at still a cryogenic temperature to a heat exchanger and heating it in indirect heat exchange with a thermal fluid which is provided in a reservoir at a thermal fluid temperature above the cryogenic temperature of the pressurized process fluid. Once heated to a suitable temperature the compressed gas may be dispensed to the compressed gas receiver or stored in one or more compressed gas storage vessels for later use.Type: ApplicationFiled: May 11, 2023Publication date: September 7, 2023Applicant: Air Products and Chemicals, Inc.Inventors: Michael Cacciapalle, Joseph P. Cohen, David Jonathan Chalk, David John Farese, Anthony R. Kyvelos

Publication number: 20230137335Abstract: A hydrogen generator can adjust production as necessary depending on station usage. When the generator is running at a high output and there isn't enough usage from a dispenser, then excess hydrogen can be fed to storage in at least one trailer. As the generator attempts to match usage rates, it may slow down. If the production rate is slowed and the dispensing need for hydrogen subsequently increases, then the required additional supply can be provided from the at least one trailer until the generator ramps up output to meet the increased demand. The trailer storage can allow for matching of usage with production. At least one trailer can be maintained at each pressure level at a station to enable trailers to be removed as they become full or to be replaced as they become empty to match station demand and provide import and export capability.Type: ApplicationFiled: October 29, 2021Publication date: May 4, 2023Applicant: Air Products and Chemicals, Inc.Inventors: ANTHONY R. KYVELOS, JOSEPH P. COHEN

Patent number: 11287089Abstract: The invention relates to a process for fueling of vehicle tanks with compressed hydrogen comprising splitting ammonia into hydrogen and nitrogen in an ammonia cracking unit, compressing the hydrogen from the ammonia cracking unit, and dispensing the compressed hydrogen to the vehicle tanks in a hydrogen fueling unit comprising one or more dispensing units, wherein chilled ammonia is used to cool the compressed hydrogen before being dispensed to the vehicle tanks by heat exchange between the compressed hydrogen and the chilled ammonia so that the chilled ammonia is heated, and transferring the heated ammonia to the ammonia cracking unit.Type: GrantFiled: April 1, 2021Date of Patent: March 29, 2022Assignee: Air Products and Chemicals, Inc.Inventors: Joseph P. Cohen, Lucas A. White, Robert Gregory Wolf

Patent number: 5517827Abstract: The present invention is a tunnel freezer which incorporates a "dual flow" design whereby the refrigerant is introduced at each end of the tunnel and withdrawn from the middle of the tunnel. A key to the present invention is that the dual flow design allows one to confine the pressure gradient for leaks between the ends of the tunnel where it will not be a concern since the item entrance and exit ports (which ports provide a ready access for leaks) are located at the ends of the tunnel.Type: GrantFiled: November 2, 1994Date of Patent: May 21, 1996Assignee: Air Products and Chemicals Inc.Inventors: Edward F. Kiczek, Joseph P. Cohen, David J. Klee, Robert J. Shaw

Patent number: 5509277Abstract: The present invention is a combination immersion/impingement tunnel freezer. A solid conveyor belt moves the items to be frozen through an initial immersion section wherein the conveyor belt is immersed in a bath of liquid refrigerant. Subsequently, the conveyor belt moves the items to be frozen through an impingement section wherein the evaporated refrigerant from the immersion section is directed toward the solid conveyor belt at a high velocity and at an angle substantially perpendicular to the longitudinal axis of the tunnel.Type: GrantFiled: December 14, 1994Date of Patent: April 23, 1996Assignee: Air Products and Chemicals, Inc.Inventors: Edward F.
