  • Patent number: 9802838
    Abstract: A method and apparatus are disclosed for treating process water which is loaded with gaseous compounds and/or possibly with solids and comes from a wet-cleaning installation for cleaning process gas, e.g., from a melt-reduction subassembly or from a direct-reduction subassembly. Process water is introduced in a tank in a first process stage and degassed on the basis of reduced solubility of the dissolved compounds. The tank has, on its upper side, a gas-collecting chamber, in which the separated-off gases are collected and from which these are discharged. Likewise, the treated process water is discharged from the tank via a drainage means.

  • Patent number: 8097069
    Abstract: A pressurized container (10, 20) for containing oil and a gas dissolved therein at a constant overall average pressure at a pressure above atmospheric pressure comprising a means (11a, 11b, 11c, 11d, 21a, 21b, 21c, 21d) for introducing a local area of reduced pressure within the oil. Preferably the local area of reduced pressure result in the gas dissolved in the oil evolving from the oil. This enables gas to be evolved from the oil without needing to reduce the pressure of the entire volume of oil which the gas is to be evolved from. The evolved gas and remaining oil occupy a greater volume than did the gas containing oil and consequently the pressure in the vessel will increase. This will allow the gas to be drawn off while the overall pressure of the container (10, 20) is maintained.

  • Patent number: 7967892
    Abstract: A water deaerating system and method are provided. The first end of an open-ended conduit is placed beneath the surface of a body of oxygen-rich water. The conduit extends into a housing and where the second end of the conduit resides at a location in the housing that is above the surface of the body of oxygen-rich water. A vacuum is applied to a spatial region defined within the housing above the location of the second end of the conduit. The oxygen-rich water is pumped through the conduit and exits the second end of the conduit to enter the spatial region of the housing. The oxygen-rich water descends through the housing due to gravity. The oxygen-rich water's descension is interrupted and the vacuum operates to remove oxygen from the oxygen-rich water so-descending to generate oxygen-depleted water.

  • Patent number: 6171465
    Abstract: A longitudinally horizontal pressure vessel desalts a fluid mixture of oil, an emulsion of oil globules encapsulated in salt water casings, gas and/or free water. A vertical wall splits the vessel into a double length flow path extending from an inlet to separate outlets for discharging the gas, the free water and the oil. A plurality of vertical baffles at intervals between the inlet and the outlets are divided along horizontal lines into a lowermost perforated zone for passing free water, a lower central zone for blocking passage of the emulsion, an upper central perforated zone for stripping the salt water casing from the oil globules and for passing oil and an uppermost open zone for passing gas. The line dividing the lower and upper central zones of each baffle are higher than the corresponding line of each preceding baffle along the flow path extending from the inlet to the outlets.
