    摘要： A flotation apparatus may include a flotation chamber having a side wall and a base, a stirrer, a sparging device associated with the stirrer, a first foam-collecting device arranged in an upper region of the flotation chamber for the purpose of collecting a foam product formed during the flotation process, and a charge line for charging the flotation chamber with pulp, wherein the charge line leads into the flotation chamber at a point above the stirrer and an ejector is present in the charge line. Further, a flotation method is performed in two stages inside a flotation chamber of a flotation apparatus, wherein an ejector is used in a first flotation stage and a stirrer is used in a second flotation stage.

    摘要： A fluid separation apparatus for separating a fluid mixture including at least two fluids having different densities comprising a vessel having a vortex generation zone located within a fluid reservoir which includes a vortex generation wall which increases the rotational velocity of a fluid mixture flowing through the vortex generation zone and directs the fluid mixture from the fluid inlet toward the upper surface of the fluid reservoir. The vessel also includes a fluid inlet which extends into the vortex generation zone; a first fluid outlet through which the less dense fluid exits the vessel; and a second fluid outlet through which the denser fluid exits the vessel. The apparatus further comprises a gas bubble generator which introduces gas bubbles into at least a portion of the fluid mixture before the fluid mixture enters the vessel through the fluid inlet.

    摘要： A pumpbox apparatus includes a reservoir volume having a first inlet for receiving a feedstock stream and a second inlet for receiving a water stream, the reservoir volume being in communication with a discharge outlet disposed to discharge accumulated liquid from the reservoir volume. The reservoir volume is operable to accumulate the feedstock stream and the water stream in the reservoir volume while withdrawing a discharge stream through the discharge outlet to cause a flow of liquid through the pumpbox. The first inlet defines a first flow velocity region between the first inlet and the second inlet and a second flow velocity region between the second inlet and the discharge outlet. The first flow velocity is lower than the second flow velocity to facilitate flotation of a low specific gravity portion of the feedstock through the first region toward an upper surface of the liquid accumulated in the reservoir volume.

    摘要： In reviewing the oil industry for the past 30 years there has been a need for a low maintenance, low cost, space saving Induced Gas Flotation Cell. With this said, a method has been invented to do this by making several changes in the present design philosophy of induced Gas flotation. First by providing a cylindrical vessel we have made a stronger unit with better structural integrity, and minimizing the opportunity for accelerated corrosion, secondly by changing the vital operations of the unit, specifically the recirculation rate of the system, lowering the overall discharge flow and increasing the discharge pressure we have been able to increase retention time and increase bubble dispersion, part and parcel with this change is the addition of multiple Eductors in each cell providing greater gasification per cell. The combination of these changes provides a greater overall efficiency thus the overboard water quality is improved using a smaller vessel to accomplish the objective. As important, is the placement of the Eductor in the vessel creating a rolling effect to move separated oil to a spillover point for collection. Thus the collection point is improved by eliminating costly mechanical wipers and using multiple adjustable spillover weirs in each cell to recover the collected oil contaminant. during the process and will help preclude upset and or surge conditions from affecting the water quality at the effluent. The overall design and combined affect of these important features makes this an improvement over all conventional technology used today. The above features are a marked advancement, when taken in combination, to current induced gas flotation technology.
