  • Device for the separation of mercury from caustic soda in chlor-alkali plants
    Patent number: 8216444
    Abstract: The invention relates to a device for breaking the electrical continuity of the stream of caustic soda produced in mercury-cathode chlor-alkali plants. The device is comprised of a vessel internally subdivided into three compartments by two flow-conveying septa, the three compartments being in communication and defining a caustic soda tortuous flow-path allowing the centrifugal deposition of mercury microdroplets released by the upstream amalgam decomposer.
    Type: Grant

    Inventors: Giovanni Meneghini, Raffaello Bertin
  • End-box for mercury cathode alkali chloride electrolysis cell
    Patent number: 8202405
    Abstract: There is disclosed an inlet and outlet end-box design for mercury cathode chlor-alkali electrolysis cells of extended lifetime, comprising a composite mechanical structure consisting of a carbon steel bottom entirely supporting the mechanical solicitations, a plastic cover, and a hydraulic head device for washing the mercury and the amalgam. The device is partially extractable thereby allowing the withdrawal of foreign materials accumulated during operation with no need for opening the end-boxes.

  • Amalgam decomposer for mercury cathode cells for alkali chloride electrolysis
    Patent number: 8062712
    Abstract: The invention relates to an amalgam decomposer for mercury cathode chlor-alkali cells. The amalgam decomposer of the invention contains a filling of carbon steel rings whose external surface is provided with a catalytic coating for amalgam decomposition consisting of one or more electrically conductive metals carbides. The internal surface of the rings is free of catalytic coating and wettable by the amalgam, while the external carbide catalytic coating is not wettable by the amalgam thereby favoring hydrogen evolution.
