  • Publication number: 20240207802
    Abstract: 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.

  • Publication number: 20220397117
    Abstract: Operation of a multistage compression system comprising at least one centrifugal compressor having a dry gas seal with opposed seal faces, for compressing a gas feed having a variable flow rate is improved by operating the or at least one centrifugal compressor in a low power mode where the opposed faces of the dry gas seal are not in contact during periods when gas flow through the centrifugal compressor(s) is not sufficient for normal operation. Such operation not only reduces damage to the dry gas seals and hence improves reliability, but also reduces the overall power requirement of the overall compression system.

  • Publication number: 20220397118
    Abstract: A stable discharge pressure of compressed hydrogen gas generated from the electrolysis of water is achieved and maintained at the outlet of a “hybrid” multistage compression system comprising at least a first section comprising at least one centrifugal compressor powered at least in part by electricity generated from at least one renewable energy source and a further section downstream of the first section, wherein the further section comprises at least one reciprocating compressor.
