Abstract: 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.

Abstract: Disclosed is a pharmaceutical composition, comprising metronidazole or a pharmaceutically acceptable salt thereof, sucrose acetate isobutyrate (SAIB), and ethyl acetate. Also disclosed is a method treating or preventing a protozoal or bacterial infection or disease, comprising administering to a non-human subject in need thereof a therapeutically effective amount of the pharmaceutical composition.

Abstract: A bio-renewable conversion process for making fuel from bio-renewable feedstocks is combined with a hydrogen production process that includes recovery of CO2. The integrated process uses a purge gas stream comprising hydrogen from the bio-renewable hydrocarbon production process in the hydrogen production process.

Abstract: A process and apparatus for producing a hydrogen-enriched product and recovering CO2 from an effluent stream from a hydrogen production process unit are described. The process utilizes a CO2 recovery system integrated with a PSA system that produces at least two product streams to recover additional hydrogen and CO2 from the tail gas stream of a hydrogen PSA unit in the hydrogen production process.

Abstract: A process and apparatus for producing a hydrogen-enriched product and recovering CO2 from 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 CO2 and some impurities. The CO2-rich tail gas stream is compressed and sent to a CO2 recovery unit, where a CO2-enriched stream is recovered. The CO2-depleted overhead gas stream is recycled to the PSA system that produces at least two product streams.

Abstract: 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.
