    Abstract: A grit removal system for tanks with a need to remove settled solids (e.g., anaerobic digester tank) is described. The system is especially suitable for a large tank, preferably having a flat floor, and it works well while submerged under a liquid. Specifically, a periphery-driven rack & pinion mechanism drives a shaft to rotate about a center pivot, and scrapes settled solids towards tank periphery, where the solids fall into a pit on the tank floor. A drainage opening inside the pit, when opened by a valve, is used to flush out the solids through a standpipe into a settlement tank for final dewatering and solid disposal. The system is compatible for continuous tank operation, and is useful for stirring tanks requiring periodic sediment removal.

  • Patent number: 8623221
    Abstract: A sand separator for capturing sand and rock debris from recovered natural gas fracturing fluid includes a cylindrical, high-pressure-rated vessel disposed vertically and immediately downstream of the gas wellhead. High pressure fracturing fluid enters the top of the separator into an inner flue extending coaxially downward to terminate a spaced distance above the bottom of the vessel. Transverse baffles spaced apart along the length of the flue extend through the flue to the inner walls of the vessel to keep the flue centered within the separator. As the fluid enters the separator, openings through the flue near the vessel inlet permit lighter weight and gaseous constituents to escape the fluid and bypass the flue, thereby reducing the velocity of the fluid remaining inside the flue. As the remaining fluid falls to the bottom of the vessel, it further slows as it reverses direction to rise between the flue and the vessel walls.

  • Patent number: 8444851
    Abstract: The system is for the reception and transport of dry lime mud from a continuously operating pressurized filter in a causticization process. A tube valve is used as an outlet from the pressurized process. The tube valve has a minimum length that is twice a diameter of the tube. A column of lime mud can be held within it as a pressure lock. The column of lime mud can be caused to descend through the tube valve by controlling a difference in pressure between an inner surface and an outer surface of the tube such that the diameter of the tube expands essentially uniformly along its length by 5-10% or by at least 4-6 millimeters.

  • Patent number: 8236185
    Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.

  • Patent number: 8225944
    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.

  • Publication number: 20120152864
    Abstract: A separator for separating oils from waste water and solids. Waste liquids are drained into a baffle tube of the separator so that the oils rise and the waste water and solids migrate to the bottom of the separator. A collection head having a restriction is located at the bottom of the separator and is adapted for suctioning the waste water and the solids therein and carrying the same to a discharge outlet of the separator. Waste liquids drained into the separator provide the hydraulic force to accelerate the waste water and solids into the collection head. Liquids drained into the separator also provide the hydraulic force that allows the oils to be drained from the top of the separator.

  • Publication number: 20120012540
    Abstract: A grit removal system for tanks with a need to remove settled solids (e.g., anaerobic digester tank) is described. The system is especially suitable for a large tank, preferably having a flat floor, and it works well while submerged under a liquid. Specifically, a periphery-driven rack & pinion mechanism drives a shaft to rotate about a center pivot, and scrapes settled solids towards tank periphery, where the solids fall into a pit on the tank floor. A drainage opening inside the pit, when opened by a valve, is used to flush out the solids through a standpipe into a settlement tank for final dewatering and solid disposal. The system is compatible for continuous tank operation, and is useful for stirring tanks requiring periodic sediment removal.
