Abstract: 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.

Abstract: In the feeding of a slurry of comminuted cellulosic fibrous material to a digester (continuous or batch) in the production of chemical pulp, one of the tanks used in the feed system (which preferably includes a high pressure feeder) may be eliminated without consequent loss of its function by providing a single tank with the combined functions of controlling the level of liquid in a slurrying conduit which supplies slurry to a slurry pump, and storing and substantially continuously supplying liquid to a make-up liquid pump connected to the digester. The single tank preferably surrounds the slurrying conduit and is substantially concentric, and in liquid communication, with it. A gap of 3-48 inches may be provided between the bottom of the conduit and a connection to the slurry pump. A screen or strainer may be provided in the gap, which is substantially surrounded by the tank. The return system from the low pressure outlet of the high pressure feeder to the slurrying device (like the conduit and tank surrounding it, or a conventional clip tube) may be devoid of one or more of an in-line drainer, level tank, centrifugal separator, and surge tank.

Abstract: The flow of a liquid slurry of comminuted cellulosic fibrous material (e.g. wood chips) in a vertical vessel is made more uniform by providing a plurality of vertically spaced sets of either substantially continuous or discontinuous protrusions which extend inwardly from the internal surface of the vessel a maximum distance of between about 2-12 inches. A preferred vessel is a continuous or batch digester. The protrusions may have an arcuate, rectangular, isosceles or scalene triangular, right triangular, or trapezoidal cross-section, and may be spaced from each other vertically between about 1-12 feet, and have a height of between about 1-3 feet. Discontinuous protrusions have a preferred arcuate spacing of between 1-10 feet.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining and applying a distribution of oxidizing agents in delignification of a pulp bleaching cycle. The method obtains an incoming kappa value of an unbleached pulp slurry and a target kappa value expected for a bleached pulp slurry. A model generates a sequence kappa factor based on these values, and a total equivalent chlorine (TEC) factor from the sequence kappa factor and the incoming kappa value. Scenarios are simulated using the TEC factor, each scenario specifying a unique distribution of dosage targets for oxidizing agents and having a total consumption score for the oxidizing agents that is determined based on the dosage targets for the oxidizing agents. A scenario with the lowest total consumption score is selected, and the model applies the dosage targets of oxidizing agents for the selected scenario during the pulp bleaching cycle.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing material processing. In one aspect, a method includes collecting, from a set of sensors, a set of current manufacturing conditions. Based on the set of current manufacturing conditions collected from the sensors, a set of current qualities of a material currently being processed by manufacturing equipment is determined. A baseline production measure for processing the material according to the set of current qualities is obtained. A candidate set of manufacturing conditions that provide an improved production measure relative to the baseline production measure is determined. A set of candidate qualities for the material produced under the candidate set of manufacturing conditions is determined. A visualization that presents both of the set of candidate qualities of the material and the set of current qualities of the material currently being processed is generated.
