摘要： A fiber mat is formed on a screen cylinder of a pressurized fiber filtering device used to filter particles from a liquid stream. The fiber mat is a fine particle filter to remove small particles from the liquid stream. The fiber mat is formed by injecting cellulosic fibers into the liquid stream flowing into the fiber filtering device. These fibers collect on the screen cylinder as the liquid flows through the cylinder. The collection of fibers forms the fine filtering mat.

摘要： Chemical pulp is produced from a slurry of comminuted cellulosic fibrous material using a beneficial additive such as AQ, or polysulfide. In the first treatment zone the effective alkali concentration and temperature conditions are such so that substantially no alkali degradation of the cellulose occurs, but so that the material is effectively impregnated with the additive. Then the material is treated with an alkaline cooking liquor, at cooking temperature, to produce a chemical cellulose pulp with higher yield or strength than if the low temperature, low alkali, additive pretreatment was not practiced. Typical alkali and temperature conditions in the first zone are less than 10 g/l expressed as NaOH; and between about 80-130° C., e.g. about 80-110° C. The first zone is preferably a feed system (which may include a separate impregnation vessel) for a continuous digester, while cooking is in a continuous digester.

摘要： Kraft pulp of increased strength and bleachability may be produced with decreased consumption of effective alkali, and at a lower H factor, by keeping the dissolved organic material (DOM) concentration low substantially through the entire kraft cook, including by extracting high DOM liquid from at least one part of a continuous digester and replacing it with much lower level DOM liquid. Existing pulp mills having two-vessel hydraulic, one-vessel hydraulic, or other systems may be retrofit to provide for extractions and additions of low DOM dilution liquor (including substantially DOM-free white liquor). Also, commercial size batch digesters (8 tons per day of pulp or more) can be operated with low DOM liquor to produce increased strength pulp. Using dilution with low DOM liquor also results in reduced H factor and effective alkali consumption, and increased bleachability.

摘要： 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.

摘要： In minimizing effluents from a cellulose pulp mill, liquid effluents from a bleach plant are concentrated, and then incinerated to produce a residue including sodium, sulfate, and sodium chloride. This residue is distilled with sulfuric acid to produce gaseous hydrogen chloride and remaining residue, the HCl being used in chloride dioxide production for the bleach plant, while the remaining residue is passed to the recovery loop (e.g. recovery boiler). Sulfur containing gases from the non-condensible gas system may be combusted to produce gaseous sulfur dioxide, which is then converted to sulfuric acid, to distill the residue. Where a non-chlorine bleach plant is provided, the liquid effluents may be concentrated in evaporators and then passed directly to the recovery boiler. The liquid streams in the mill are managed by a cascade principle to reserve the cleanest water for only those processes where it is needed while minimizing its use where it is not necessary.

摘要： A hydraulic accumulator prevents oil with gas entrained in it from exiting the accumulator. The accumulator comprises a completely static structure which provides laminar flow of oil from a gas pad to the accumulator outlet. The laminar flow is preferably provided by a plurality of tubes disposed between the gas pad and the outlet, each tube having a substantially greater length than the largest cross-sectional dimension. The tubes are preferably rigid and circular in cross-section, and the passageways defined between the tubes also have a substantially greater length than the largest cross-sectional dimension. The accumulator can either be a low pressure accumulator or a high pressure accumulator. With a high pressure accumulator it is desirable to provide a float switch or like sensor to ensure that the tubes within a tube bundle are always fully immersed in oil. The accumulator is particularly useful in association with an atmospheric or pressure diffuser for treating paper pulp, which includes one or more screens which are hydraulically reciprocated.

摘要： A deinking system for use with recycled paper pulp includes a number of gas sparged hydrocyclones mounted around the outer periphery of a foam separation vessel, with the slurry outlet from each hydrocyclone introducing slurry into the vessel below the level of liquid in the vessel, and above the accepts outlet from the bottom of the vessel. An annular trough is provided adjacent the top and outer periphery of the vessel, and has a bottom sloping to one or more drain outlets. The hydrocyclone discharge conduits into the vessel are tangential to cause bubble-releasing swirling of the slurry in the vessel. The cyclone preferably is pedestal-less, and has a single gas inlet, and a deflector within the annular air jacket of the hydrocyclone. At least one substantially conical substantially uniform back pressure generator may be disposed in the hydrocyclone slurry outlet, a foam conveyance and breaking device may be associated with the drain outlet from the trough, and a foam and rejects handling tank connected to the foam conveyance and breaking device and including a substantially spiral downwardly extending feed ramp may also be provided.
