    Abstract: A sweep membrane separator includes a membrane that is selectively permeable to a selected gas, the membrane including a retentate side and a permeate side. A mixed gas stream including the selected gas enters the sweep membrane separator and contacts the retentate side of the membrane. At least part of the selected gas separates from the mixed gas stream and passes through the membrane to the permeate side of the membrane. The mixed gas stream, minus the separated gas, exits the sweep membrane separator. A sweep gas at high pressure enters the sweep membrane separator and sweeps the selected gas from the permeate side of the membrane. A mixture of the sweep gas and the selected gas exits the sweep membrane separator at high pressure. The sweep membrane separator thereby separates the selected gas from the gas mixture and pressurizes the selected gas.

  • Publication number: 20150122814
    Abstract: A dehumidifier comprises: a first channel for transporting air at a first pressure; a second channel for transporting air at a second pressure lower than the first pressure; and a graphene oxide barrier separating the first channel and the second channel. The relatively lower pressure of air in the second channel causes water vapour to be drawn out of the air in the first channel.

    Abstract: The present disclosure relates to a method for removing carbon dioxide from hydrocarbons, the method comprising the steps of: (a) contacting a feed stream comprising hydrocarbons and carbon dioxide with one or more gas-separation membranes to produce a hydrocarbon-rich retentate gas stream and a permeate gas stream rich in carbon dioxide, the retentate gas stream containing less carbon dioxide relative to the feed stream; and (b) passing at least one of the retentate gas stream or the permeate gas stream through an absorption unit to produce a hydrocarbon-rich gas phase and a liquid absorbent phase containing said carbon dioxide. The present disclosure also relates to a system for doing the same.

  • Patent number: 9023133
    Abstract: A vacuum pumping arrangement is described for pumping a gas stream containing hydrogen or other hydrogen-containing gas. The arrangement comprises a pumping mechanism for receiving the gas stream and exhausting a pumped gas stream at a sub-atmospheric pressure, and, downstream from the pumping mechanism, an ionic conducting membrane having one side exposed to the pumped gas stream and another side exposed to oxygen or other source of oxygen. In one example, the membrane is permeable to hydrogen, which permeates across the membrane to react with oxygen adsorbed on the other surface of the membrane. In another example, the membrane is permeable to oxygen anions, which permeate across the membrane to react with hydrogen within the gas stream.
