  • Patent number: 8590713
    Abstract: A centrifugal separator having a separation chamber and a collection chamber utilizes an axially-oriented structure which extends from the spin structure, or spin plate, up and into the vortex finder. The axially-oriented structure decreases turbulence within portion of the separator in axial adjacency with the spin structure, including the separation chamber in which the solids are collected. The reduction of turbulence substantially reduces the entrainment of solids in the rising stream of liquid flowing to the vortex finder, and thus increases the efficiency of the separator. The spin structure may comprise a truncated cone mounted with a portion of the truncated cone in the separation chamber and the remainder in the collection chamber.

  • Patent number: 8506824
    Abstract: A method for treating waste water and sewage by introducing high pressure wash water or other fluids including gas into a housing of a hydro-cyclone and creating a cyclone with an enhanced and controllable vortex for increased removal of putrescible materials. Waste water and sewage is introduced into the housing and into the cyclone vortex. By the very high centrifugal force generated, suspended inorganic grit is quickly separated from the wash water and organic matter. The water with organic matter is then discharged typically out of the top of the housing, for returning to a water treatment plant for further processing. At this time, the separated inorganic grit, as a concentrated grit liquid, is typically funneled downwardly by gravity through a bottom of the hydro-cyclone housing for waste discharge removal.

  • Patent number: 8480606
    Abstract: A system is disclosed for removing gas bubbles from blood during circulatory assist procedures. Such bubbles are generated, along with particulate matter, in an extracorporeal circulatory bypass system by the pump, oxygenator and other components. Current filters are inefficient at removing small bubbles that can cause neurological defects and renal and other organ failures in the patient. An active filter apparatus and method is disclosed that forces the bubbles to the center of the system where they are removed from the blood before the blood exits the filter. The filter comprises an axially elongate cylindrical shell with a blood inlet, a blood outlet and a gas outlet. A motor driven impeller spins the blood within the shell and forces the gas toward the center by centripetal force, utilizing the buoyancy effects of the bubbles in blood, whereby the bubbles can be bled off at the center of the filter.

    Abstract: Systems and methods for separating sand and other solids from oil and other fluids produced from a well. The present systems and methods introduce the fluids at relatively high speed into a generally cylindrical separation chamber. The fluids flow in a generally circular path within the chamber, causing the solids and higher density fluid/media to be urged outward from the axis of the chamber as the fluids flow from the upper portion of the chamber. Because the solids become concentrated at the outer wall of the chamber, the fluid in a central portion of the chamber is substantially free of the solids, and can be removed from the chamber via a fluid outlet. The solids concentrated at the outer wall of the chamber continue to move downward into an accumulation chamber in which the fluid speed is reduced, allowing the solids to settle out of the fluid.

The filtering system includes a cylindrical outer casing with the pipe of the water to be filtered penetrating tangentially through its base, using centrifugal force in the first filtering stage to separate the particles with greater density. Then the liquid takes a helicoidal path and passes through different filtering devices, such as mesh or rings with the filtered and, therefore, clean water finally being collected in an appropriately perforated central pipe that comes out of the filter through the center of its lower base. The system is used for the cleaning of liquids, basically water, in agriculture for localized irrigation, in industry, or the environment.

  • Patent number: 8147845
    Abstract: Reovirus can be used to selectively remove ras-mediated neoplastic cells from a cellular composition. It is of particular interest to purge autographs which may contain neoplastic cells with reovirus before transplanting the autographs back into the recipient, thereby reducing the risk of introducing or reintroducing neoplastic cells into the recipient.

  • Patent number: 8147757
    Abstract: The present invention describes a system and method for accurately measuring the concentration of a substance within a filter housing. A concentration sensor and a communications device are coupled so as to be able to measure and transmit the concentration of a particular substance within the filter housing while in use. This system can comprise a single component, integrating both the communication device and the concentration sensor. Alternatively, the system can comprise separate sensor and transmitter components, in communication with one another. In yet another embodiment, a storage element can be added to the system, thereby allowing the device to store a set of concentration values. The use of this device is beneficial to many applications. For example, the ability to read concentration values in situ allows integrity tests to be performed without additional equipment.

  • Patent number: 8137567
    Abstract: A method for fluid remediation and removing particulates from an aqueous stream is described herein. The method can use a separation component and a clarifier component. A slurry can flow to a scalping shaker which can separate the slurry, forming a first effluent. The first effluent can flow from the scalping shaker to a first section and can be agitated. The first effluent can be pumped to a mud cleaner and cleaned, forming a second effluent. The second effluent can flow into a second section and can be agitated. The second effluent can be pumped to a desilter and can be desilted, forming a third effluent. The third effluent can flow to a third section. The third effluent can be pumped to a second tank of the clarifier component. The third effluent can be decelerated within the second tank, forming a clean effluent.

  • Patent number: 8096425
    Abstract: An extraction system and process for extracting bitumen from a slurry containing bitumen, solids and water. The system comprises a cyclone separation facility for separating the slurry into a solids component stream and a bitumen froth stream with the bitumen froth stream including water and fine solids. The bitumen froth stream is then delivered to a froth concentration facility for separating the bitumen froth stream into a final bitumen enriched froth stream, and a water and fine solids stream. The final bitumen enriched froth stream is suitable for further processing. The system of the present invention is preferably mobile so that the cyclone extraction facility and the froth concentration facility can move with the mine face at an oil sands mining site, however, it is also contemplated that the system can be retrofitted to existing fixed treatment facilities to improve the operational efficiency of such fixed facilities.

  • Patent number: 8097051
    Abstract: A separator for liquids, in particular condensate, from liquid-loaded compressed gases-generally serves, by coarse separation of condensate from the compressed gases, to protect downstream prefilters of cold dryers or adsorption dryers against overload due to condensate. In the separator of the invention, in a pot-shaped housing, a separator element in the form of a hollow cylinder is arranged, which consists of a multiplicity of flow chicanes formed from guiding bodies and impact bodies. The moisture-loaded gases are passed from the interior of the hollow cylinder to the exterior via these flow chicanes, condensate separating off on the chicanes and collecting in the collecting space.

    Abstract: A method and apparatus for dewatering a mixture of granulate and water are disclosed. In accordance with one example of the system described herein, the apparatus includes a casing as well as hollow sieve body with side walls formed as a sieve, the sieve body being arranged in the casing and suspended thereto. The sieve body tapers towards the bottom, and a clearance is formed between the casing and sieve body. For delivering the granulate-water mixture an inlet is arranged in the upper part of the sieve body. A corresponding outlet for the dewatered granulate is located at the bottom of the sieve body. The inlet is arranged in the sieve body and the sieve is formed such that the water laterally escapes through the sieve into the clearance due to centrifugal and gravitational forces when passing through the sieve body from top to bottom.
