  • Publication number: 20180273154
    Abstract: Disclosed are a configuration system and a method for configuring a ballast water treatment system for treating ballast water of one or more ballast tanks in a vessel. The ballast water treatment system is configured to circulate ballast water between a tank outlet and a tank inlet of a first ballast tank. The method includes obtaining structural parameters of the first ballast tank. These structural parameters include a compartment number parameter indicative of a number of compartments in the first ballast tank. Control data for the ballast water treatment system based on the structural parameters is then determined. The control data includes a first volume parameter indicative of a first ballast water volume to be circulated. The control data is provided to the ballast water treatment system.

  • Patent number: 4224190
    Abstract: Alcohols are dehydrogenated to form ketones, using a catalyst containing liquid indium dispersed and retained in the pore structure of a porous carrier. The catalyst is prepared by mixing powdered In.sub.2 O.sub.3 and MgO, firing the mixture at 900.degree.-1150.degree. C. for 5-20 hours, and activating the catalyst by passing through a reducing gas.

  • Patent number: 4193894
    Abstract: A catalytic material for oxidation of sulfur dioxide to sulfur trioxide at any temperature above 300.degree. C., comprising a catalyst which at reaction conditions is a melt including sulfatized vanadium ions as the active catalytic component and two different promoters and which is dispersed in an inert porous carrier.The first promoter comprises cesium ions, optionally in combination with ions of another alkali metal such as sodium, potassium or rubidium, known to promote vanadium catalysts. The second promoter comprises ions of a metal such as aluminum, magnesium, yttrium or lanthanum, which does not promote formation of inactive V.sup.4 species and the oxide of which has a heat of formation greater than 100 kcal per oxygen atom and is at least partly soluble in the heavily sulfatized environment of the melt.
