  • Patent number: 8551335
    Abstract: A dual stage filter includes an outer filter with a first media and an inner filter with a second media. A barrier is between the first media and the second media. The barrier directs fluid flow between the first and second media. The barrier creates a flow path between the first and second media, such that a working fluid, which is desired to pass through the first and second media, is directed by the barrier and flows through the second media, and such that another fluid, which is not desired to pass through the second media, is directed by the barrier and separates from the working fluid. Using the barrier, the dual stage filter can employ either or both upward flow and downward flow to achieve efficient fluid separation, for example fuel water separation in an engine fuel filter.

  • Patent number: 8257585
    Abstract: A debris catcher uses induced circulation from a venturi to urge debris laden flow into the lower end of a housing. An inlet tube maintains velocity so as to keep the debris moving with the fluid stream as it goes up the inlet tube. A screen fits over the open end of the inlet tube and runs down around the inlet tube toward the entrance of the debris laden fluid into the lower end of the housing. There is a clearance around the cylindrical portion of the screen so some flow can exit that way. There is also an open exit through the top of the screen that can be reached after the fluid stream makes two hairpin turns. Many modules can be stacked. Each module has a large screen area for flow to exit and progressive modules can have smaller screen openings in an uphole flow direction.

  • Patent number: 8153850
    Abstract: According to an embodiment, a biomass conversion subsystem produces methane and/or alcohol and residual biomass. A pyrolysis or a gasification subsystem is used to produce thermal energy and/or process gasses. The thermal energy may be stored thermal energy in the form of a pyrolysis oil. A fuel conversion subsystem produces liquid hydrocarbon fuels from the methane and/or alcohol using thermal energy and/or process gasses produced by the gasification or pyrolysis subsystem. Because the biomass production system integrates the residual products from biomass conversion and the residual thermal energy from pyrolysis or gasification, the overall efficiency of the integrated biomass production system is greatly enhanced.

  • Publication number: 20120067807
    Abstract: A waste/sediment collecting container has a front vertical wall, a back vertical wall, two side vertical walls, and a sloped bottom surface. Along the lowest portion of the sloped floor surface lays a debris grate which allows water and pieces of sediment to pass through (but prevents larger pieces of waste from passing). The collection container includes a sump directly beneath the debris grate for collecting heavy sediment which passes through the grate. Sloped walls along the sides of the sump lead to U-traps on both sides of the container that allow liquid to pass through but prevent any solid waste from leaving the sump. Solid waste may be removed from the sump by removing the threaded service cap from the drain hole. Located beyond the traps are filter chambers having drain holes for inserting sediment filters which liquid passes through and exits the container.

  • Publication number: 20080149553
    Abstract: A separator provides improvements for better separation of an effluent into constituent parts and greater ease of use. A tapered basket provides improved flow and better filtration. A baffle directs effluent into the basket with greater force. An asymmetrical flange prevents mis-orientation the basket and baffle. An improved oil valve provides a locking mechanism to prevent dislodging of the valve during cleaning. An alternative valve uses a sensor to sense an oil/water interface and close the oil valve appropriately. A top seal prevents leakage of effluent at connection points with the lid of the housing. An underground unit allows below floor level installation of the separator. A bidirectional unit can be reversed to provide flow in either direction. A dual purpose tank can be used to store both separated oil and oil from operations for common removal.

  • Patent number: 6666968
    Abstract: An oil filter assembly has an outer canister in which full flow and bypass flow filtration sections are operatively housed in a nested relationship. Oil forced into the canister has imparted thereto a vortex flow pattern which forces contaminant particles in the oil away from the full flow filter section before the oil passes therethrough. The bypass filtration section is disposed within the full flow filtration section and creates a second vortex flow pattern in the oil which induces a small portion thereof to flow through a bypass filter element while at the same time causing the entire balance of the oil to bypass this filter element and be discharged from the canister after having traversed the filtering portion of only the full flow filtration portion of the filter assembly.

  • Patent number: 6103107
    Abstract: Ferrofluid coated particles resulting from a ferrofluid materials separation process are washed with a solvent which is the same material as the liquid carrier employed in the ferrofluid. The result is a "dirty" solvent which is a very weak ferrofluid. The dirty solvent is then filtered or centrifuged to remove dust particles and other impurities and then the solvent is recovered by distillation in a distillation unit. The solvent can then be reused in the materials reclamation process. The residue in the distillation unit is surfactant-coated particles of ferrofluid. This residue is mixed with either clean or unprocessed solvent in the right proportion and the slurry is passed through an attritor to convert it to a high grade ferrofluid. The ferrofluid can also be reused in the materials separation process.

  • Patent number: 3948767
    Abstract: A method and apparatus are provided for separating oily particles from an emulsion thereof in an aqueous liquid. The emulsion is passed through a bed of oleophilic granules supported on a foraminous support, the oleophilic granules, by virtue of their density, pressing against the foraminous support and the bed is unconfined downstream thereof so that the granules in the bed are fluidized by the passage of liquid therethrough. The oily particles are removed from the emulsion by the oleophilic granules in the bed, and the oily material accumulates and agglomerates and is transported out of the bed by the passage of liquid therethrough. The movement of the liquid then carries the oily droplets which are formed in the bed and deposits them upon a screen positioned downstream of the bed, the aqueous liquid passing through the screen in purified form. The oil accumulates on the screen and is propelled by the moving liquid into an oil reservoir positioned downstream of the screen.

These large oil drops are then intercepted and extracted by a steeply inclined screen and caused to flow to storage in the form of a fine oil film propelled by the force of the flow of the aqueous liquid through the screen.
