  • Patent number: 10478770
    Abstract: Process and apparatus for producing helium, neon, or argon product gas using an adsorption separation unit having minimal dead end volumes. A second separation unit receives a stream enriched in helium, neon, or argon, and a stream is recycled from the second separation unit back to the adsorption separation unit in a controlled manner to maintain the concentration of the helium, neon, or argon in the feed to the separation unit within a targeted range.

  • Patent number: 9808755
    Abstract: Methods and apparatuses for separating CO2 and sulfur-containing compounds from a synthesis gas obtained from gasification of a carbonaceous feedstock. The primary separating steps are performed using a sour pressure swing adsorption (SPSA) system, followed by an acid gas enrichment system and a sulfur removal unit. The SPSA system includes multiple pressure equalization steps and a rinse step using a rinse gas that is supplied from a source other than directly from one of the adsorber beds of the SPSA system.

  • Patent number: 8778051
    Abstract: A process for separating a primary gas component from a feed gas mixture comprising the primary gas component and secondary gas components in four or more adsorption beds. The process comprises subjecting each of the four or more adsorption beds to a repetitive cycle. The repetitive cycle comprises, in sequence, a feed step, a pressure decreasing equalization step, a provide purge step, a blowdown step, a purge step, a pressure increasing equalization step, and a repressurization step. During the pressure decreasing equalization step, rinse gas is co-currently introduced simultaneous with the withdrawal of pressure equalization gas. Rinse gas is formed by compressing blowdown gas and/or purge gas effluent from the adsorption bed undergoing the purge step. The process is particularly suited for separating H2 from a reformate stream.

  • Patent number: 8551229
    Abstract: Hydrogen sulfide is removed from a hydrogen rich gas stream using adsorbents having a low loss of carbon dioxide adsorption capacity upon sulfur loading including high purity silica gels, titania or highly cross-linked, non-chemically reactive resins.

  • Patent number: 8337674
    Abstract: Helium is introduced as an additive to any of the oxygen streams introduced into an ozone generator, such as a dielectric discharge (cold plasma) ozone generator, where the effluent of the generator is directed to an adsorption process for separating the ozone from the oxygen. Also disclosed is an improved PSA cycle, which is designed to reduce the amount of make-up helium and oxygen required to sustain the ozone generation and recovery process.
