Publication number: 20240384428Abstract: An apparatus to purify water and provide the purified water to one or more electrolyzers for manufacture of hydrogen can include a purification unit positioned to receive water from a demineralization unit to purify the water and output the purified water to at least one electrolyzer of an electrolyzer house. The flow of water can be adjusted to maintain a minimum flow of water passing through one or more beds of a polisher while accounting for the demand of water at the electrolyzers. Flow adjustments can be made between providing all the purified water to the electrolyzers during high demand operations to other configurations in which little or no purified water is fed to the electrolyzers and, instead, that water is recycled back to the water purification unit.Type: ApplicationFiled: May 18, 2023Publication date: November 21, 2024Applicant: Air Products and Chemicals, Inc.Inventors: GRAEME RICHARD WILSON, TIMOTHY EDWARD CONWAY, MATTHEW WILLIAM AKHURST, FIONA VICTORIA LESLIE

Publication number: 20240279825Abstract: A process and apparatus for utilization of an absorption chiller for hydrogen production can include an arrangement configured for providing at least one heated waste stream of fluid from at least one hydrogen production unit to an absorption chiller generator to power the absorption chiller. Coolant can be generated via the heated waste stream for feeding coolant from the generator to an evaporator for cooling a chilling medium to a pre-selected chilling temperature to provide cooling to one or more process elements. The warmed chilling medium can be returned to the absorption chiller evaporator for subsequent cooling back to the pre-selected chilling temperature to provide a closed-circuit cooling arrangement. The waste fluid fed to the generator can be output as a cooled waste fluid for returning to hydrogen production for further use or be output for treatment and/or disposal.Type: ApplicationFiled: February 21, 2023Publication date: August 22, 2024Applicant: Air Products and Chemicals, Inc.Inventors: GOWRI KRISHNAMURTHY, FRANK J.

Publication number: 20240207802Abstract: An apparatus to provide cooling water to multiple facilities including a hydrogen plant that includes electrolyzers for manufacture of hydrogen and/or an ammonia plant including ammonia manufacturing for making ammonia. The apparatus can include a first cooling tower configured to provide cooling water at a first temperature for providing cooling to elements of the ammonia manufacturing and/or hydrogen plant. The apparatus can also include a second cooling tower configured to providing cooling water at a second temperature that is higher than the first temperature for providing cooling for gas coolers and electrolyte coolers of the hydrogen plant. The first and second cooling towers can be configured to utilize sea water or fresh water. The cooling towers can also be arranged and configured to permit substantial capital cost reductions while also providing improved maintenance and safety features as well as improved operational flexibility.Type: ApplicationFiled: December 21, 2022Publication date: June 27, 2024Applicant: Air Products and Chemicals, Inc.Inventors: Graeme Richard Wilson, Nicolas John Haryett, Matthew William Akhurst

Publication number: 20240141524Abstract: A process and apparatus for electrolyte solution production can be provided so that a modular production can be provided. The modular electrolyte production can be provided so that the production system is mobile for being used in multiple different plants at different geographical locations that are remote from each other. Embodiments can be configured so that electrolyte production is made for a plant specific application that provides an electrolyte solution having a pre-selected concentration of at least one electrolyte for use in at least one electrolyzer of the plant. The production can be mobile so it can be provided at different sites to make the same type of solutions or different solutions specific to the needs of the plants it may support. Some embodiments can utilize an electrolyte material handling device that also modular and mobile. Other embodiments can be configured to utilize an on-site electrolyte material handling device.Type: ApplicationFiled: October 31, 2022Publication date: May 2, 2024Applicant: Air Products and Chemicals, Inc.Inventors: GRAEME RICHARD WILSON, TIMOTHY EDWARD CONWAY, BARRY W. DIAMOND, MATTHEW WILLIAM AKHURST, SENTHILKUMAR NANJAPPAN

Publication number: 20240109783Abstract: A process and apparatus for reducing wastewater generated during production of ammonia that can have different levels of production (e.g. ammonia production can vary from 10% to 100% production capacity, etc.) can be configured to minimize or eliminate wastewater from ammonia production. Embodiments can be adapted so that wastewater is stored in a vessel and providable to a scrubber used for processing an ammonia vapor containing stream so that ammonia within that stream can be recovered and mixed with other liquid ammonia product for subsequent storage or use. Embodiments can be implemented so the scrubber stream that may utilize a liquid to perform the scrubbing is recyclable in a way that minimizes or even eliminates formation of a wastewater stream, which can significantly improve process efficiency and provide improved environmental operation as compared to conventional approaches.Type: ApplicationFiled: September 29, 2022Publication date: April 4, 2024Applicant: Air Products and Chemicals, Inc.Inventors: KEVIN RICHARD MADTHA, GRAEME RICHARD WILSON
