    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.

    Abstract: A method of separating includes mixing a fluid into a mixture that has been separated from an oil well stream and that includes water, oil, and gas. The mixture including the fluid is fed into a separator and allowed to separate into a water phase and an oil/fluid phase. The cleaned water phase is removed from the separator via an outlet for water. The oil/fluid phase is subjected to a separation step separating the oil/fluid into an oil phase and a gaseous phase, from which gaseous phase the fluid is recovered by a condensation step and recycled for injection into the mixture. The separator is a liquid-liquid/gas separator in which the pressure is in the range of 0.5 bar to 25 bar, while the mixture including the fluid is separated into the water phase and an oil/gas phase.

    Abstract: In some embodiments, a chamber may be configured to separate oil and gas. For example, the oil and gas may be separated as they exit a compressor, an oil storage tank, etc. In some embodiments, the gas may be a heavy gas and the oil may be compressor oil. One or more heated baffles may interact with the oil and gas to increase the velocity of the gas flow to inhibit the gas from absorbing into the oil. In some embodiments, when the compressor feeding the chamber is operating at a decreased compression rate, the chamber may continue to heat the oil to vaporize impurities out of the oil. The impurities may then be vented out of the chamber through the bleed valve to a gas inlet scrubber.

    Abstract: An apparatus for carrying out a three-phase separation during treatment of wastewater and sludge, which includes a gas collector (1) which traps gases that rise in the settling basin during the treatment process. The gas collector has an inclined outer surface (2, 3) which ensures that sewage sludge can slide down unhindered. The angle of inclination (?) can be adjusted in order to adapt the apparatus to different sewage sludges. The gas collector has a flexible tube (4) which is guided around a plurality of reversing or bending surfaces (5, 6, 7, 8) so that sections (10, 11) of the tube form the inclined outer surfaces (2, 3). Another section (15) of the tube defines the interior volume (V) of the gas collector. The resulting gas collector is simple to produce and effectively prevents the separation apparatus from becoming clogged by particles of sewage sludge adhering to the outer surfaces of the gas collector.

  • Patent number: 6843832
    Abstract: The compound/curvilinear immiscible liquid separator has a separator section with an outer, elongated, cylindrical shell aligned vertically opening into an upper transition section and vapor dome at the top and a lower transition section and solid/heavy crude containment section at the bottom. A center column is disposed in the axial center of the separator section and a plurality of serially connected curved plates are disposed between the outer shell and center column to define an elongated curvilinear flow path having reverse flow pathways. An oil-water-gas mixture is introduced into the separator section under pressure past heating coils and through the curvilinear path, the lighter density oil entering and being removed from the top of the center column, and heavier sludge and brine collecting in the containment section. Gases bubble up through the center column and are removed from the vapor dome.

  • Patent number: 6758886
    Abstract: A three-phase separator for separating off from a fluid gas and particles contained therein, includes at least one pair of two gas collection caps extending in a horizontal longitudinal direction (L) and each having a plate section. The plate sections converge in the downward direction. At the bottom ends the plate sections leave an inlet passage, elongated in the longitudinal direction, for the fluid containing particles and an outlet passage, elongated in the longitudinal direction, for settled particles. A discharge opening for fluid, opening into the settling chamber, is provided at a level higher than the inlet and outlet passages. The inlet passage and the outlet passage are located in the extension of one another, viewed in the longitudinal direction.

  • Patent number: 6706094
    Abstract: A system for rapid collection of large volumes of dissolved gases from groundwater pumps the water from a large-diameter passage through a small-diameter restrictor passage, and then into a flow-through collection chamber. The small-diameter passage causes a drop in the hydrostatic pressure of the groundwater traveling therein, causing spontaneous ebullition of gas bubbles which are then collected in the collection chamber. Testing reveals that the gases are collected in proportion to their presence in the groundwater, and thus the system allows accurate quantification of concentrations of dissolved gas in groundwater. The system may beneficially be made easily portable, thereby allowing its use in the field as well as in laboratory settings.

  • Publication number: 20030159581
    Abstract: A method and system for sea-based handling/treatment of fluid hydrocarbons (oil) with associated gas comprise a first separation step in a high-pressure separator (18) installed on the sea bed, from which is output an oil flow containing an essentially predefined percentage of residual gas. The oil containing residual gas is carried through a riser (22) up to a surface vessel/production ship (12), where it is subjected to a second separation step in a second separator (24) incorporated in a low-pressure surface plant on board the vessel (12), this separated residual gas being used as fuel for direct/indirect generation of electric power for the operation of the underwater and above-water sections of the system. Water and gas produced in the first separation step is returned to a suitable reservoir by the use of a multiphase pump.

  • Patent number: 6508859
    Abstract: A device for removing entrained air or gas from fluids includes a first chamber having a fluid inlet and an outlet, a second chamber, adjacent said first chamber, having a plurality of channels, a porous barrier separating the first chamber and the second chamber and a vent in fluid communication with the second chamber. The inlet is connected to the first chamber through at least one fluid passage. Fluid flows from the inlet, through the passage, and into the first chamber. A fluid dead zone adjacent the barrier assists an air or gas bubble to coalesce and pass through the barrier into the second chamber. The plurality of channels within the second chamber collect the air or gas and direct it to the vent in communication with the channels. A clip, or similar device, may be used to secure the device to medical equipment adjacent the patient or fluid source.

  • Patent number: 6346141
    Abstract: A system and method are provided for supplying breathable gas to an underwater habitat submerged in water. A flow of respired gas that includes metabolically-produced carbon dioxide is extracted from the underwater habitat and mixed with water from the surrounding environment. As a result of such mixing, carbon dioxide in the respired gas is substantially absorbed by the water while a first gas is produced. Moisture in the first gas is filtered out to produce a breathable gas which is then introduced back into the underwater habitat.
