摘要： Systems and methods as disclosed herein automatically provide real-time dosing corrections for an industrial process wherein enzyme blends are applied to natural fibers for pulp/paper production. An initial enzyme blend (e.g., enzymes and supporting formulation components, as relevant) and respective dose rates are selected to be applied based on expected fiber surface substrate characterization, expected fiber quality characterization, the physical conditions of the system being treated, respective characteristics of the initially selected enzyme blend components, etc. Upon application of the initial enzyme blend, online sensors provide real-time feedback data corresponding to measured actual values for the fiber surface substrate characterization and fiber quality characterization. A replacement enzyme blend (enzymes and supporting formulation components) and respective dose rates thereof is dynamically selected based on the feedback data. The enzyme dosing stage can be optimized responsive to product changes and/or variations in fiber sources/blend and/or physical conditions, substantially in real time.

摘要： Systems and methods are disclosed herein for contextual data analysis and proactive intervention in industrial plant processes. Each of multiple data streams in an industrial plant are mapped to a common hierarchical data structure, wherein the data streams correspond to respective values or states associated with unit operations, assets, and process streams in the plant. The mapped data streams define hierarchical process relationships between subsets of the unit operations, assets, and process streams. Real-time data is collected to populate at least one level of the hierarchical data structure for certain data streams, wherein future outcomes are predicted for downstream operations based on the collected real-time data for at least one data stream, and at least one other data stream having a defined hierarchical process relationship therewith. Upon ascertaining that predicted future outcomes correspond to issues requiring intervention, output signals are generated based thereon for operator alerts and/or automated control.

摘要： A chemical product consumption monitoring device using force sensors integrated into a sealed sensor housing for retrofit installation on liquid or solid product chemical feeding systems used in water treatment. The sensor design is flexible and can be used with products having different form factors such as discs, bottles, pellets, or pails. The sensor is used to monitor the product consumption rate based on weight or percentage for inventory management by forecasting replenishment scheduling and provide a process for automatic ordering. By combining the product consumption measurement with other sensor data from the dispenser, chemical delivery system, or process, allows tracking dispenser performance and alarming if malfunctioning. Additionally, using data from different sources provides remote visibility for scheduling maintenance and troubleshooting.

摘要： Various embodiments of the present disclosure relate to proactive dosing optimization chemical feed units producing an output solution (such as an oxidizing biocide) therefrom. Online sensors generate signals corresponding to directly measured variables for respective process components. Information is selectively retrieved from models relating combinations of input variables to respective industrial process states, wherein various current process states may be indirectly determined based on directly measured variables for respective system components. An output feedback signal is automatically generated corresponding to a detected intervention event based on the indirectly determined process state. A controller may receive the signal and implement, e.g., regulation of oxidizing biocide feed for optimization of end products and/or performance metrics.

摘要： Methods to improve water treatment for industrial uses are described. One method involves admixing source water, such as from a river or other flowing source or body of water, with a at least one water-soluble cationic polymer and at least one chloramine and a coagulant and/or flocculant to provide a treated water. The at least one water-soluble cationic polymer and at least one chloramine are present in an effective amount to improve water treatment efficiency, such as in allowing use of reduced amounts of coagulant and/or flocculant, and/or reduced suspended solids, turbidity, and/or color clarification.

摘要： A method is provided for decision support in regulating an adhesive coating applied to Yankee dryers. Online sensors are configured to continuously measure stock characteristics, and additional sensors provide actual stock flow rate and machine speed. A controller predicts potential natural coating application from a fibrous sheet generated from the stock to the Yankee dryer surface, substantially in real time, based on the measured characteristics and sensed actual machine values. An output signal may be provided to a display unit, wherein an optimal adhesive coating feed rate may be determined and displayed for operator decision support. The controller may in an automatic mode be configured to regulate the adhesive coating feed rate based on a comparison of one or more determined optimal values associated with respective actual values. The method may include identifying fiber source changes in real time, and predicting a natural coating potential based partly on predetermined correlations.

摘要： Methods to preserve starch present in pulp are provided and also methods to control calcium precipitation and/or scaling in digesters or BOD systems. The methods can be performed as part of a papermaking process. Process water containing pulp can be treated with a chloramine. Process water containing pulp with native starch can receive a double treatment with at least one biocide, such as chloramine, and at least one oxidant, such as sodium hypochlorite. The treatment can be performed in any suitable manner. The treatment can be performed at one or more stages or locations in a papermaking system. A target residual chloramine value or range can be achieved by the treatment. Packaging sheets/boards and other paper products manufactured using the methods provided exhibit superior strength and other desirable characteristics.
