  • Patent number: 7906089
    Abstract: Horizontal gas-liquid scrubbing systems and associated gas scrubbing methodologies are provided. In one embodiment, a horizontal duct scrubbing system includes a horizontally disposed housing having a waste gas inlet and a treated gas outlet, a liquid inlet manifold disposed within the horizontally disposed housing, the liquid inlet manifold comprising a plurality of nozzles oriented to spray a scrubbing liquor co-current to the flow of a gas stream flowing through the horizontally disposed housing, and a demister located proximal the treated gas outlet, where the horizontally disposed housing is substantially free of flow deflection members between the liquid inlet manifold and the demister. The gas stream may include sulfur dioxide, and the system may be capable of removing at least 71 vol. % sulfur dioxide from the gas stream.

  • Publication number: 20060254925
    Abstract: Methods and systems for controlling operating conditions of electrolytic cells are provided, particularly aluminum electrolytic cells. The method may includes the steps of measuring offgas temperature from the electrolytic cell, comparing the measured offgas temperature to a target offgas temperature, and completing a predetermined action in response to the comparing step. The predetermined action may include one or more of changing a feed rate of feed materials supplied to the electrolytic cell or inspecting a crust of the electrolytic cell for an undesired condition, such as a crust hole. The system may include an electrolytic cell adapted to contain a molten metal mixture, a hopper adapted to provide feed material to the electrolytic cell, a hood adapted to contain offgas from the electrolytic cell, an exhaust duct interconnected to the hood and containing a thermocouple for measuring offgas temperature, and a control panel for receiving temperature measurements from the thermocouple.
