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.

Process and apparatus for compressing hydrogen gas in a hybrid compression system

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.

Process and apparatus for operating a compression system

An apparatus and process can be configured for filtering and cooling air to be fed to a gas turbine while also vaporizing at least a portion of fuel to be fed to the gas turbine. Intake air can be passed through a filter house for filtration. While passing through the filtration house, a liquid fuel can be passed through the filter house to be vaporized or partially vaporized therein via heat exchange with the air passing through the filter house, which can also cool the air as it is passing through the filter house. Filtered, cooled air can be output from the filter house for feeding to a gas turbine as an oxidant while the at least partially vaporized fuel can also be output from the filter house for feeding to the gas turbine for being combusted therein.
