  • Patent number: 10165713
    Abstract: Conventional shielding materials are based on single material either toxic lead or barium based compounds and any matrix made therefrom contains only single phased barium based compounds, thereby posing limited radiation shielding capacity. Since brine sludge, an industrial toxic waste product, generated in chloralkali industry contains multiple compounds; there is a need to provide a process which enables the preparation of multi-phase based radiation shielding materials. In view of the above, the present invention provides advanced non-toxic radiation shielding materials utilizing tailored brine sludge and a process that enables conversion of toxic elements like chromium, zinc, copper and vanadium present in brine sludge into non-toxic shielding phases, thereby enabling to convert a toxic waste material into highly value added advanced radiation shielding materials possessing homogeneous radiation shielding matrix.

  • Patent number: 10145017
    Abstract: An efficient electrolysis system for sodium chlorate production may include round or oval cells, reactors, a product pump transfer, a buffer tank, a circulation pump, and explosive clad plate, all of which are connected by way of pipelines. Inlet and the outlet of each cell are separately connected with the reactor via titanium pipes, allowing the electrolyte to recirculate naturally between the cells and the reactors. The outlet of every cell is conical while each reactor includes a standard electrolytic unit with three to eight cells. The electrolytic units are modularly identical and symmetrically linked to the buffer tank. Within each unit, adjacent cells are connected with the explosive clad plates. The buffer tank may be divided into two parts—part A and part B—with part A connecting with the overflow port of the reactor via pipeline, and the part B connecting with the reactor via the circulation pump.

  • Publication number: 20090038956
    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 favouring hydrogen evolution.

  • Publication number: 20020008020
    Abstract: The invention concerns a motorized device for adjusting the interelectrodic gap in mercury cathode electrolysis cells, mainly consisting of a frame, to which a number of anodes are suspended, movable in the vertical direction by means of a single jackscrew driven by a gear motor acting on double levers. The jackscrew with the motor and the lever system are fixed to a main frame, supported on the cell bottom by means of supports positioned on adjustable columns, while the above mentioned movable frame (also called sub-frame) carrying the anodes, is connected to the lever arms by means of four hinged supports.

  • Patent number: 5589044
    Abstract: An electrode for mercury chlor-alkali electrolytic cells includes a plurality of activated electrode elements consisting of flat sections standing on edge and having recesses on their lateral surfaces which extend from the lower edge to the upper edge of the lateral surfaces. The recesses in the lateral surfaces promote the transport of the gas bubbles produced electrolytically away from the area of the electrode gap and achieve a boundary surface as free of gas bubbles as possible between the anode and the electrolyte in the area of the electrode gap for the purpose of improving the energy efficiency.
