摘要： Provided is a centrifuge media separator for separating blast particulate from fine particulate carried by air flowing from a blast cabinet and through the media separator. The centrifuge media separator comprises an upper panel, a lower panel, and an outer wall. The upper panel has a central opening formed therein. The outer wall is configured in a truncated logarithmic shape and which extends between the upper and lower panels. The outer wall has at least one particulate escape aperture formed therein. The upper panel, lower panel and outer wall collectively define a curvilinear air passageway having an inlet and an outlet. An air foil extends from the outer wall in to the air passageway. The distance than the air foil extends in to the air passageway is adjustable. The inlet is configured to allow a flow of air to enter the air passageway and circulate therethrough toward the outlet. The escape aperture is configured to exhaust the blast particulate out of the passageway. The central opening is configured to exhaust the fine particulate out of the passageway.

摘要： Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a pumping pressure created by the porous media of the rotating coalescer to maintain positive recirculation of filtered blowby gases through a potential leak gap between a static housing inlet and a spinning component of the rotating coalescer. In some arrangements, the porous media is fibrous media. The filter media may be pleated or non-pleated. The positive recirculation caused by the pressure balance prevents unfiltered blowby gases from bypassing the media of the rotating coalescer from the upstream side to the downstream side of the filter media through the gap. During operation, the pressure balance between the upstream side and downstream side of the filter media maintains the positive recirculation, which in turn maintains a high filtration efficiency.

摘要： Methods of recirculating clean air in an atmosphere of an enclosure comprise directing an input air stream from the atmosphere of the enclosure through a coiled duct at a rate sufficient to stratify the input air stream within the coiled duct according to a molecular weight of components of the input air stream and to form a heavy fraction stream and a light fraction stream, wherein the heavy fraction stream is relatively enriched in carbon dioxide as compared to the light fraction stream; withdrawing the heavy fraction stream from the coiled duct; and returning the light fraction stream from the coiled duct to the atmosphere of the enclosure.

摘要： The present invention relates to a process for producing sodium bicarbonate crystals. Sodium carbonate derived from TRONA ore is mixed with a treated mother liquor produced in a downstream process to form a sodium carbonate solution. The sodium carbonate solution is subjected to a crystallization process that produces sodium bicarbonate crystals. The sodium bicarbonate crystals are separated from the sodium carbonate solution to form a mother liquor that includes silica. To remove the silica in the mother liquor, the mother liquor is directed to a reactor where an aluminum salt is mixed with the mother liquor to precipitate hydrous aluminum oxide which adsorbs silica thereon. The hydrous aluminum oxide with adsorbed silica is removed from the mother liquor. This produces the treated mother liquor that is mixed with the sodium carbonate and which forms the sodium carbonate solutions.

摘要： An offloading vacuum system. The system has a tank to capture debris from an excavation site. The debris is pulled into the tank due to a blower pulling air into an attached hose. An internal conveyor within the tank conveys material to an offloading hub. The offloading hub has a ground-facing door which opens to deposit debris into an external conveyor. The external conveyor, when deployed, can move debris from below the tank to a dump container with a wall greater than a height of the tank.
