摘要： Low temperature steaming and slurrying of wood chips results in significant improvement in treatment, the chips being maintained at a temperature below 110.degree. C. (more desirably at about 105.degree. C. or less, and most desirably at about 100.degree. C. or less) until actually heated to cooking temperature. Steaming may be accomplished utilizing a vertical chip bin with one dimensional convergence and side relief or a horizontal steaming vessel, the steaming device connected to a high pressure feeder. A pump having an NPSHR less than the NPSHA may be used for drawing slurry into the high pressure feeder from the steaming device, or a pump may be disposed between the steaming device and the high pressure feeder for forcing slurry into the high pressure feeder through a conduit including a radiused elbow. The steaming is practiced at a pressure of 5 psig or less, preferably substantially atmospheric steaming is practiced. The pulp produced typically has strength properties at least about 10% greater than the pulp produced from material where it is steamed and slurried at temperatures in excess of 110.degree. C.

摘要： A system for feeding wood chips entrained in cooking liquor to a high pressure feeder connected to a continuous digester includes a vertical treatment (e.g. steaming) vessel, a metering device connected to the discharge from the steaming vessel, a generally vertical chip chute extending downwardly from the metering device, and a slurry pump having an inlet. The slurry pump pumps the slurry from an outlet thereof to a high pressure feeder low pressure inlet. In order to minimize the effect of changes in liquid volume upon the operation of the system, and to provide separate control of liquor volume and chip volume, a substantially vertical liquor tank having a top and bottom the bottom including a discharge opening above the slurry pump inlet is provided. A conduit directly connects the liquor tank discharge opening with the slurry pump inlet. A pressure isolating device may be used in the system if it is to operate at superatmospheric pressure rather than atmospheric pressure.

摘要： 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.

摘要： A multi-stage pressure diffuser is provided for treating paper pulp or similar comminuted cellulosic fibrous material. Two different subvolumes are defined within the annular screen of the pressure diffuser by a tubular baffle hung from adjacent the top of the vessel, and a transverse wall near the middle of the vessel. Wash liquid is introduced into the top stage, extracted liquid passes through the bottom of the baffle, and is removed through a liquid outlet at the top of the vessel. That removed liquid is then reintroduced into the bottom stage as wash liquid, and the extracted liquid from the bottom stage is discharged from the vessel at the bottom. The screen assembly may be blanked at the area of the transverse wall dividing the subvolumes from each other, in order to minimize the possibility of mixing of the extraction flows in the different stages.

摘要： A chip bin for wood chips in a continuous digester system includes internal steaming that is controlled in response to both the interior temperature across the level of chips in the bin, and the level of chips in the bin, so as to substantially prevent cool, non-condensible gas-laden chips from accumulating at the top of the chip column in the bin, and to substantially prevent steam blow-through. The temperature probe used in the chip bin has a temperature sensing portion with a length of about ten to twenty feet instead of the conventional five foot length, and extends across the level of the chips to a position about five feet below the level of chips. Control of steam added to the bin is provided utilizing a controller which controls the position of one or more valves in one or more steam conduits, each valve having multiple open positions and a closed position. A vacuum and pressure relief device is disposed in a non-condensible gases vent from the bin which minimizes the potential for gross gas flow variations across it. The relief device includes a solid interior peripheral portion of the vent, a gate mounted for pivotal movement by a pivot shaft, and a casing which is a cylindrical sector (having a sector angle of about 30.degree.-60.degree.) in which the gate pivots. The casing is mounted in the solid interior peripheral portion and a brush seal is provided between the gate and the cylindrical sector casing.

摘要： In a pulp treatment vessel, such as a kraft pulp continuous vertical digester, a cellulose slurry is caused to flow in the vessel interior in a flow path. A substantially annular void is formed at at least one point along the flow path, and dilution or treatment liquor is introduced into the substantially annular void so that the liquor is substantially uniformly distributed about the periphery of or into the slurry. The annular void may be formed by a step out in the vessel, and the uniform introduction of dilution liquor may be accomplished utilizing one or more openings, such as a plurality of openings substantially evenly spaced around the substantially annular void, e.g. using a screen surface. The screen surface may be substantially vertical or conical.

摘要： Dense, tramp material, is efficiently separated in a comminuted cellulosic fibrous material feed system, for example in a chemical cellulose digester feed system, in a simple but effective matter. By merely utilizing a generally vertical conduit and a slurry flow within it (which may be augmented by high speed liquid introduction), that is caused to turn in a radiused path, centrifugal force allows separation of the tramp material into a cavity beneath the radius transition without requiring any mechanical element to engage the slurry. Appropriate purges, baffles, and discharge mechanisms may be provided. Alternatively, a tramp material separator may be built into an otherwise conventional metering screw in a digester feed system, or one or more centrifugal separators can be provided downstream of the slurry pump in a chip slurry transport system or digester feed system.

摘要： The sulfide ion concentration and sulfidity of kraft cooking liquor during kraft cooking of cellulose pulp is selectively increased. After treatment in a first treatment zone in which impregnation or kraft cooking takes place using a kraft cooking liquor having a first sulfide ion concentration and sulfidity, black liquor is extracted from the material, liquid is withdrawn from the material and dilution liquid is added to the withdrawn liquid and the withdrawn liquid with dilution liquid is reintroduced. In a second treatment zone after the first zone a second kraft cooking liquor is introduced having a second sulfide ion concentration and sulfidity greater than the first sulfide ion concentration and sulfidity (typically by about 20-50%), including by manipulating controlling the flow rate of extraction and the flow rates of withdrawal of liquid and addition of dilution liquid. The pressure of the continuous digester is controlled in a unique manner that avoids disruptions to the column of pulp continuously moving downwardly in the digester, anywhere in the digester, but particularly avoids non-uniform, unstable material in the countercurrent washing zone. The pressure is controlled by withdrawing liquid from, and introducing liquor into, the digester at at least one additional extraction-dilution loop aside from the main extraction of the digester and the wash dilution liquid introduction mechanism below the wash screens. Pressure can also be maintained (e.g. at about 130-170 psi) by also controlling the amount of wash dilution liquor, and by varying the extraction flow.
