  • Publication number: 20230219869
    Abstract: There is provided a process for producing a target material-enriched product from a target material-comprising gaseous feed material, wherein the target material-comprising gaseous feed material includes a carrier agent-interacting material, comprising: treating the target material-comprising gaseous feed material for effecting depletion of the carrier agent-interacting material within the target material-comprising gaseous feed material, with effect that a carrier agent-interacting material-depleted gaseous material is produced; and fractionating the carrier agent-interacting material-depleted gaseous material via a membrane, with effect that a product is obtained that is enriched in the target material relative to the target material-comprising gaseous feed material. The membrane includes a carrier agent to which the carrier agent-interacting agent is detrimental in response to emplacement of the carrier agent-interacting agent in mass transfer communication with the carrier agent.

  • Publication number: 20180243697
    Abstract: There is provided a process for effecting separation of at least a gaseous permeate-disposed operative material from a gaseous supply material that is being supplied to a gaseous supply material receiving space that is disposed in mass transfer communication with a permeate receiving space through a membrane, the gaseous supply material including an operative material that defines a gaseous supply material-disposed operative material, and the membrane including a gel. The process includes replenishing liquid material that has become depleted from the gel.

  • Publication number: 20080302725
    Abstract: An apparatus for the adsorption of components of fluids or the catalytic reaction of components of fluids. The apparatus has numerous membranous elements formed as fibers, strands, strips, or the like. Each element possesses a desirable property such as the ability to adsorb certain components of a fluid or the ability to catalyze a particular chemical reaction. The elements are packaged into bundles of elements structured such that sufficient space exists between individual elements to allow for the flow of a fluid through the bundle. The bundle is contained within an impermeable casing containing one or more inlet ports and one or more outlet ports. The elements may have materials that are able to adsorb specific substances. The elements also may have materials that are able to catalyze certain chemical reactions.

  • Patent number: 7361800
    Abstract: Chitosan membranes chelated with silver or cuprous material may be used to separate olefins from a mixture of olefins and paraffins. The feed stream is humidified, demisted, treated to remove sulfur compounds and passed to a cell having a chitosan membrane containing chelated silver or cuprous compounds. The process has a reasonable flux rate and is operable at reasonable temperatures and pressures. The process could be used in an olefin separation train.
