  • Publication number: 20120118835
    Abstract: A wash column for processing a suspension of solid particles in a liquid comprising a bed forming chamber in which a packed bed of solid particles can be formed, filtrate extraction means for extracting liquid from the suspension as to form the packed bed of solid particles in the bed forming chamber, and a suspension supply line for supplying the suspension directly to an end of the bed forming chamber, wherein the suspension supply line ends in the bed forming chamber.

  • Patent number: 7425273
    Abstract: The invention relates to a method and apparatus for processing a suspension. According to the invention, a suspension is led into a washing column in which at least one filter element is present, so that near the filtering element, a packed bed of particles forms. The bed is disintegrated under the influence of the impulse of a washing liquid, while particles from the bed are incorporated in the washing liquid.

  • Patent number: 6355092
    Abstract: The invention relates to an apparatus for performing membrane gas/liquid absorption at elevated pressure, comprising a pressure vessel in which a membrane unit is provided for separate feed-through of the gas phase and the liquid phase, in such a way that exchange of components to be absorbed can take place between the gas phase and the liquid phase, the flow direction of the gas phase through the absorber being essentially perpendicular to the flow direction of the liquid phase through the absorber. The invention further relates to a method for performing gas/liquid membrane absorption employing this absorber, in particular for the absorption of CO2, H2S, mercury (vapor) and/or water (vapor) from a gas phase at elevated pressure. The invention finally relates to a method for refining natural gas using the absorber and method according to the invention.
