    Abstract: A system for treating produced water, for example from a SAGD bitumen production operation, has a treatment unit using chemical oxidation (CO) or electromagnetic treatment (ET) to destroy or degrade organics in the produced water. The treatment module may use CO or ET in combination with biological treatment or sorption processes or both. When the treatment module is used upstream of a steam generator, it reduces fouling in the steam generator and in any blowdown water treatment device. A brine concentrator or a crystallizer may be used to treat the blowdown water. The treatment module may be used in combination with a nanofiltration (NF) or reverse osmosis (RO) membrane filter. Optionally, the produced water may be treated with an ET process such as microwaves directly upstream of a steam generator or upstream of a concentrator or crystallizer in a blowdown water stream.

    Abstract: There is a method of facilitating the consolidation of fine tailings through the application of an electrical current. The fine tailings include a combination of at least some water and some clay particles. Electrodes are placed into contact with the fine tailings. An AC voltage with a DC offset is applied to the electrodes to separate water from the clay particles and to induce movement of the separated water to a collection area. The separated clay particles can consolidate more readily than unseparated clay particles. In an embodiment, the fine tailings are mixed fine oil sands extraction tailings which include residual hydrocarbons. In an embodiment, the application of an AC voltage with a DC offset across the electrodes includes applying an AC voltage of about 1 V/cm and a DC offset of about ½ V/cm.

  • Publication number: 20140353252
    Abstract: A method of supplying engineered water for drilling or hydraulic fracturing of wells, where the water comes from either fresh sources or is recycled from drilling or hydraulic fracturing operations whereby the water is treated for example with a mechanical vapor recompression unit or other treating apparatuses and methods to significantly reduce the concentration of constituents that are deleterious to drilling or hydraulic fracturing chemistries while keeping desirable constituents, such as semi-volatile antimicrobial constituents. The final composition of the engineered water is designed to contain constituents that are optimal for drilling or hydraulic fracturing operations.

  • Patent number: 8900460
    Abstract: A method for processing interface emulsion, water, and solids contained within a separator vessel that comprises the steps of continually extracting those components from the vessel and then passing them through a gas flotation cell. The cell, which is preferably a vertical induced gas flotation cell, separates the oil and water contained in the interface emulsion and discharges recovered oil from an upper portion of the cell and treated water from a bottom portion of the cell. The recovered oil and treated water may be further processed and recycled to the vessel or sent elsewhere. The treated water may also be recycled to the cell or sent to a process sewer. Fuel gas residing in an upper portion of the cell may be cooled and passed through a splitter. All the steps of the method comprise a closed system with no air emissions.

  • Patent number: 8889404
    Abstract: A method and apparatus for producing biogas from organic matter including a container (1) which is charged with fermentation substrate by a delivery system (13), and at least two stirring mechanisms (2) arranged in the container, the stirring mechanisms having propellers (3) which are rotated and generate mostly horizontal currents of the fermentation substrate in the container. The propeller diameters, the propeller geometries, and the positions of the propellers in the container are selected such that a shared mixing zone of the medium is generated in the container. Data for determining the mean speed and/or the viscosity of the medium in the mixing zone are detected and transmitted to a control unit (4) which varies actuating variables which modify the power input of the stirring mechanism into the mixing zone and/or the composition and/or the flow behavior of the container contents.

  • Publication number: 20140326676
    Abstract: A system and process for treating water wherein water to be treated is directed to an inlet zone and from the inlet zone to a mixing zone. A flotation zone receives water from the mixing zone. A clarified water collection area is disposed adjacent the flotation zone for receiving clarified water from the flotation zone. There is provided one or more spray nozzles disposed in the mixing zone for injecting pressurized water into the mixing zone and generating air bubbles in the mixing zone such that the air bubbles are mixed with the water to be treated. A perforated plate separates the inlet zone and the mixing zone and includes an array of openings through which water to be treated passes as the water to be treated moves from the inlet zone to the mixing zone. The openings in the perforated plate give rise to a homogeneous mixture of the water to be treated and the air bubbles that result from the pressurized water being injected into the mixing zone by the one or more spray nozzles.

  • Patent number: 8877065
    Abstract: A skim tank includes a flow-control structure that forces a solid-depleted phase of a mixed-phase feed into a toroidal motion within the container to thereby provide an up-flow movement within the structure. Most preferably, at least a portion of the solid-depleted phase is recirculated to further increase up-flow movement within the structure.

  • Patent number: 8834724
    Abstract: 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.

  • Patent number: 8828240
    Abstract: A method to purify water includes the steps of providing a septic tank to hold unpurified water and having an outlet to provide a water stream for processing, and processing the water in an electrocoagulation and flocculation reactor that uses electrical energy to convert dissolved solid material in the water stream into suspended particulate form that can be subsequently filtered and separated out. The method continues with introducing air into the water stream to promote aerobic processing of contaminants and to assist in agglomeration and flocculation of suspended solid material, filtering the water stream to separate suspended solid material from the stream and to adsorb some of its dissolved contaminants, and processing the water stream with a reverse osmosis processor that provides a reject stream that provides water back to the septic tank and a recycle stream that provides unpurified water back to the water stream exiting the septic tank.

  • Patent number: 8821826
    Abstract: A method for regenerating silicon from silicon waste includes: placing and mixing silicon waste, a solvent having pH of approximately 5 to approximately 6, and a surfactant within a container; and injecting air into the container to separate floating matters and precipitates. Accordingly, since silicon is easily separated from the silicon waste, the regeneration yield of silicon is increased. Since the regenerated silicon is recyclable, it may be possible to obtain important substitution effect of high-purity silicon the entire amount of which depends on import. Moreover, environmental pollution may be reduced because the amount of the silicon waste disposed of by burial is decreased.
