Patent number: 7115157Abstract: Novel gas separation apparatus and methods are provided that help reduce the amount of process gas lost through the discharge outlet of either a cyclone separating gas/solid mixtures or a hydroclone separating gas/liquid mixtures. Significant savings are realized by minimizing losses and neutralization costs. A cyclone or hydroclone is placed within a containment vessel that creates a contained atmosphere common to both the gas outlet and the discharge outlet of the cyclone or hydroclone. Process gas mixed with the solids or mixed with the liquids in the discharge underflow are displaced from the discharge underflow and contained within the containment vessel. The displacement of the process gas is facilitated by an introduction of a small amount of purge gas to the discharge underflow exiting the cyclone or hydroclone via the discharge outlet.Type: GrantFiled: February 27, 2004Date of Patent: October 3, 2006Assignee: Tronox, LLCInventors: Harry Eugene Flynn, Robert O.

Patent number: 6616719Abstract: An air-liquid separating method and apparatus for compressed air. The high pressure air output from an air compressor is transferred through a transfer tube to pass through the cooling tube of a cooling tank. The cooling tube has a diameter larger than that of the transfer tube so that the high pressure air goes from a smaller room into a larger room and the pressure is relieved. The temperature of the high pressure air is lowered due to relief of the pressure and the pressure of the vapor is, approximately the saturated vapor pressure. The cooled high pressure air is further transferred to an air-liquid separating tank. The temperature of the air is lowered to the dew point due to further relief of pressure. At this time, the vapor contained in the high pressure air is condensed into liquid water which drops onto the bottom of the air-liquid separating tank and separates from the air.Type: GrantFiled: March 22, 2002Date of Patent: September 9, 2003Inventors: Yung Yung Sun, Chuan Ching Cheng

Patent number: 5918576Abstract: An air cleaner for an engine of the type utilized to power a motorcycle comprises a housing having an air inlet and air outlet, and an interior divided into first and second chambers. The outlet is connected to an air passage leading to the engine. The first chamber communicates with air outside of the housing though air inlet apertures. Air drawn into the first chamber is routed through a duct to the second chamber. The second chamber communicates with the outlet through a passage extending from the second chamber through the first chamber. An air filter element is positioned within the second chamber about the entrance to the passage extending to the air outlet. The air cleaner is mounted to the engine of the motorcycle with the air inlet facing the engine. The outlet of the air cleaner is connected to an air passage leading to the combustion chambers of the engine.Type: GrantFiled: October 3, 1996Date of Patent: July 6, 1999Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Hisahiro Ohoka, Masato Suzuki

Patent number: 5900159Abstract: The present invention relates to a method for separating liquid from a slurry of solid particles and liquid contained in a vessel in the presence of a gas, which comprises degasifying the slurry and passing the degasified slurry through a cross-flow filter, and separating the degasified slurry into the liquid and a concentrated slurry. The present invention further relates to a process for the preparation of heavy hydrocarbons, which process comprises contacting a synthesis gas in a reactor vessel with a slurry of solid catalyst particles and a liquid, thereby producing heavy hydrocarbons, and separating the liquid containing heavy hydrocarbons from the slurry by the said method.Type: GrantFiled: February 25, 1997Date of Patent: May 4, 1999Assignee: Shell Oil CompanyInventors: Dirk Coenraad Engel, Geert Van Der Honing

Patent number: 5853579Abstract: A treatment system is provided which can treat solid materials and/or liquid materials. Preferably, a separator initially separates liquid and solid materials, and the solid materials are deposited upon a substrate within a microwave cavity. Liquids remaining with the solid materials drain through the substrate, and the solid materials are subjected to microwaves. The liquids exiting the separator are preferably also passed through a filter assembly which retains any suspended particles remaining in the liquid, and subjects the particles to microwaves. Exhaust filters can also be provided for the microwave cavities, and the exhaust filters can also be subject to microwaves to incinerate any particles remaining in the exhaust gas. Fire tube arrangements for incinerating solid materials retained or extracted by substrates or filters are also provided.Type: GrantFiled: November 26, 1996Date of Patent: December 29, 1998Assignee: Wastech International Inc.Inventors: John M.

Patent number: 5779744Abstract: An air/liquid separator is provided in a hollow, preferably transparent, removable lid on a recovery tank of a wet pickup suction cleaner. The lid has a wall therein dividing the lid into an inlet/separating chamber and an exit chamber. Liquid and dirt entrained working air enters the inlet chamber and flows horizontally across the inlet chamber over a plurality of discharge openings passing through the lid bottom plate, such that the stream of dirty liquid and air is redirected downward through the discharge openings into the recovery tank. The plurality of discharge openings in the lid bottom plate are arranged generally progressively along the stream of liquid and air entering and flowing across the inlet chamber. The discharge openings preferably increase in size moving downstream in the inlet chamber, i.e. away from the entry into the inlet chamber. The exit chamber fluidly communicates with the interior of the recovery tank through an exit opening passing through the lid bottom plate.Type: GrantFiled: May 9, 1997Date of Patent: July 14, 1998Assignee: The Hoover CompanyInventors: David G.
