Processes and apparatuses for operating a centrifugal gas compressor. A storage tank containing a liquid buffer material is provided and used to offset density fluctuations in the gas stream passed to the compressor. The storage tank may contain a component of the high-pressure gas stream provided by the compressor, such as carbon dioxide.

Processes and apparatuses for operating a gas compressor

A bio-renewable conversion process for making fuel from bio-renewable feedstocks is combined with a hydrogen production process that includes recovery of CO. The integrated process uses a purge gas stream comprising hydrogen from the bio-renewable hydrocarbon production process in the hydrogen production process.

Integrated hydrogen production and bio-renewable conversion process

A three-product PSA system which produces three product streams from a feed gas mixture comprising a light key component, at least one heavy key component, and at least one intermediate key component is described. The three-product PSA system produces a high pressure product stream enriched in the light key component, a low pressure tail gas stream enriched in the at least one heavy key component, and an intermediate pressure vent gas stream enriched in the at least one intermediate key component.

Three-product pressure swing adsorption system

A process and apparatus for producing a hydrogen-enriched product and recovering COfrom an effluent stream from a hydrogen production process unit are described. The process utilizes a COrecovery system integrated with a PSA system that produces at least two product streams to recover additional hydrogen and COfrom the tail gas stream of a hydrogen PSA unit in the hydrogen production process.

Method of producing a hydrogen-enriched product and recovering COin a hydrogen production process unit

A process and apparatus for producing a hydrogen-enriched product and recovering COfrom an effluent stream from a hydrogen production unit are described. The effluent from the hydrogen production unit, which comprises a mixture of gases comprising hydrogen, carbon dioxide, water, and at least one of methane, carbon monoxide, nitrogen, and argon, is sent to a PSA system that produces at least two product streams for separation. The PSA system that produces at least two product streams separates the gas mixture into a high-pressure hydrogen stream enriched in hydrogen, optionally a second gas stream containing the majority of the impurities, and a low-pressure tail gas stream enriched in COand some impurities. The CO-rich tail gas stream is compressed and sent to a COrecovery unit, where a CO-enriched stream is recovered. The CO-depleted overhead gas stream is recycled to the PSA system that produces at least two product streams.

Method of recovering a hydrogen enriched product and CO2 in a hydrogen production unit

An adsorption process is provided to remove oxygen from a hydrogen stream through the use of a copper material in combination with layers of adsorbent to remove water and nitrogen from a hydrogen stream. This process is particularly useful for purification of hydrogen product gas from water electrolyzers with the hydrogen product gas having greater than 99.9 mol % purity.
