    Abstract: An improved lifting mechanism for an apparatus for continuously feeding solid particles into a pressure vessel of the type disclosed in U.S. Pat. No. 4,125,384, the lifting mechanism comprising an elongated cylindrical housing assembly operatively disposed with its axis extending at an angle to the horizontal and to the vertical. The housing assembly includes end structures closing the upper and lower ends thereof, a water and particle inlet for pressure communication with the pressure vessel of the apparatus leading downwardly into the interior of the housing assembly adjacent the closed lower end thereof and a particle outlet for pressure communication with the container of the apparatus leading downwardly from the interior of the housing assembly adjacent the closed upper end thereof. A particle supporting plate extends longitudinally within the cylindrical housing assembly between the end portions thereof and is fixedly mounted along the sides thereof between horizontally spaced diametrically opposed portions of the housing assembly. A pair of parallel endless chains have upper operative flights which extend along opposite sides of the upper surface of the plate, lower parallel return flights and arcuate ends trained about sprockets carried by the housing assembly at the ends of the plate. A series of spaced perforated particle moving structures extend between the chains and are operable during the movement of the chains through their operative flight to move therewith over the upper surface of the plate and upwardly through the space thereover defined by the upper periphery of the housing assembly so that particles introduced into the lower portion of the space through the inlet are moved positively inwardly through the liquid free surface and then discharged through the outlet in a condition in which the liquid has been substantially drained therefrom.

    Abstract: A method and apparatus supply ozone containing gas under superatmospheric pressure to an ozone delignification device. The speed of a water ring compressor is controlled so that it compresses as much ozone gas per unit time at desired superatmospheric pressure as the ozone delignification unit utilizes, with essentially no excess. The ozone containing gas is fed from the water ring compressor through a separator buffer tank which levels out pressure pulses and separates cooling water from compressed ozone gas prior to the gas entering the ozone delignification unit. The gas passes through a control valve controlled by a mass flowmeter which senses the amount of cellulose pulp fed to the ozone delignification unit. The speed control of the compressor may be provided by a differential pressure controller connected across the control valve.

    Abstract: A system and method for feeding comminuted cellulosic fibrous material such as wood chips to the top of a treatment vessel such as a continuous digester provide enhanced simplicity, operability, and maintainability by eliminating the high pressure transfer device conventionally used in the prior art. Instead of a high pressure transfer device the steamed and slurried chips are pressurized using one or more slurry pumps located at least thirty feet below the top of the treatment vessel and for pressurizing the slurry to a pressure of at least about 10 bar gauge. A return line from the top of the digester may, but need not necessarily, be operatively connected to the one or more pumps and if connected to the pumps the pressure in the return line may be reduced utilizing a pressure reduction valve and/or a flash tank. During pressurized transferring of the slurry from the pumps to a treatment vessel (which may be as little about 10 feet or as much as about a half a mile away) treatment liquid is provided which contains at least some active pumping chemical including sodium hydroxide, sodium sulfide; polysulfide, anthraquinone or their equivalents or derivatives; surfactants, enzymes, or chelants; or combinations thereof. Pseudo-countercurrent circulation of treatment liquids may be provided between stations.

    Abstract: In a method of bleaching medium consistency pulp with ozone using a mixer, ozone containing gas and about 6-15% consistency pulp are fed to the mixer, and then discharged in a first, preferably vertical, path. The mixture of pulp and ozone moves in a first part of the vertical path a time period of about 1-5 seconds at a velocity of about 1-5 m/s so that the gas and pulp do not separate during movement in this first part, and the vast majority of the pulp brightening reaction between the ozone and pulp takes place. This is preferably accomplished by passing the mixture upwardly in a small diameter conduit having a height of about 3-20 meters. Then the velocity of the pulp is slowed while still moving in the first path, preferably by feeding it directly to a much larger diameter (e. g. 1.5-10 times) conduit, so the height of the unit may be kept under 100 feet. The pulp flows in the large diameter conduit for about 0.5-5 minutes so that residual reactions take place.

    Abstract: Methane is produced from peat by solubilizing the phenolic polymers therein, and oxidizing the solute to produce short chain molecules. The short chain molecules are fermented to produce a gas that this scrubbed to remove CO.sub.2 to produce methane. Solubilizing takes place in a vertically oriented pressurized vessel that is circular in cross-section and divided into a number of regular vertically elongated compartments, each comprising a circular sector in cross-section, and extending the majority the height of the vessel. Slurried peat is fed into the top of one compartment while another compartment is being emptied from the bottom, the compartment being filled or emptied being progressively changed in response to rotation of a central shaft in the vessel. Oxidation of solubilized peat takes place in a structure that transports the solubilized peat in a substantially vertical wave path from an inlet to an outlet with oxygen being introduced at the bottoms of segments of the wave path, and CO.sub.2 being withdrawn from the tops of segments of the wave path while the solubilized peat is maintained at a pressure above atmospheric. Coolant is circulated around the wave path to remove the exothermic heat of reaction, and the coolant is flashed into steam used elsewhere in the process.

    Abstract: A slurry of recycled cellulose fibers is deinked by introducing the slurry into the first end of a vortex, sparging gas radially inwardly into the slurry to cause gas bubbles to attach to contaminants and ink particles to form an aerated slurry, discharging the aerated slurry from near the second end of the vortex into a separation vessel, effecting separation of a foam of ink laden gas bubbles from the cellulose fiber slurry in the separation vessel, and removing from the separation vessel the foam with associated ink and contaminants in a first stream, and de-inked cellulose fiber slurry in a second stream. The separation vessel is typically a foam separating vessel with separation effected by flotation, and by discharging the foam. The slurry is introduced into the flotation vessel below the liquid level in it. The slurry typically has a consistency of about 0.5-2%, and the gas to slurry volume ratio during sparging may be 0.1-1 to 1.0 (e.g. 0.2-0.7 to 1, or 0.3-0.4 to 1). The foam separating vessel may be cylindrical with a shower head at the top, and rejects therefrom directed to a rejects tank. Sparging takes place in a hydrocyclone with an outlet that may or may not be restricted; a rejects outlet may extend from a first end of the hydrocyclone to a rejects tank.

    Abstract: A method and apparatus are provided for the dehydration of low rank coal, such as lignite. The coal is formed into particles having a size of less than about 4 inches, is subjected to atmospheric steaming, and then preheating with steam at a pressure of about 20-100 psig. The particles are then entrained in liquid and fed to a high pressure feeder at which they are transferred to a high pressure circulation loop, at a pressure of between about 300-1500 psig. The particles and liquid are fed to a liquid/particles separator at the top of a vertical dehydrating vessel, and the particles at the top of the vessel are contacted by saturated steam. Condensed steam and particles flow downwardly in the dehydration vessel, and are subjected to a counter-current wash at the bottom of the vessel. A slurry of liquid and particles discharged from the bottom of the dehydration vessel has the pressure thereof gradually reduced in a second high pressure feeder, and is transferred to a low pressure loop at a pressure of between about 20-100 psig. The liquid and particles are separated, and then the particles are subjected to evaporative cooling.
