  • Patent number: 8900435
    Abstract: Carbon dioxide can be separated from gas streams using ion exchange, such as in an electrochemical cell. An anion exchange membrane can be configured to increase the efficiency of the system and to permit the flow of the carbon-containing ions within the system while reducing diffusion of protons and/or hydroxyl ions. A gas stream containing carbon dioxide can be introduced to the system on the cathode side, while a source of hydrogen-containing molecules can be introduced on the anode side. Operation of the system can separate the carbon dioxide from the gas stream and provide it at a separate outlet.

  • Publication number: 20140339162
    Abstract: Electrocoagulation (EC) may remove oil and solids from oilfield water and other raw, untreated or unprocessed water as a pretreatment for increased boron removal efficiency using a subsequent boron selective resin. Boron selective resins are efficient for boron removal, but oil and solids in water lower the boron remove efficiency and capacity.

    Abstract: A method of producing an apparatus to remove ions from water is disclosed, wherein the apparatus includes a first electrode having a first current collector, a second electrode having a second current collector, and a spacer between the first and second electrodes to allow water to flow in between the electrodes. The method includes flushing water through the spacer and subsequently exerting a force on the stack so as to compress the first and second electrodes and the spacer. Exerting a force on the stack may result in a pressure of less than 5 bar, less than 2 bar, or between 1 bar and 0.5 bar, between the electrodes and the spacer.

  • Publication number: 20140311896
    Abstract: The present invention is related to the mining industry and treatment of mineral and materials that contain gold and silver. Specifically, it is related to a process to recover gold and silver, from copper thiosulfate solutions with a autogenerated electrolysis process. The advantages of the present invention, relative to those of the state of the technique, reside in the increased velocity compared with cementation using copper, without employing electric current. Our process is characterized by operating in an electrochemical autogeneration cell, in which the anode and cathode are connected in short circuit and the anodic and cathodic compartments are separated by an ion exchange membrane. Additionally, using a copper anode and the stripped solution as the anolyte, the levels of soluble copper are maintained stable, conserving the leaching power of the thiosulfate solutions, whereby it is possible to recycle them back to the leaching stage.
