Pixact measurement technology can be utilized in several production phases and process operations of The Pulp & Paper industry
The Pulp & Paper industry can utilize Pixact measurement technology in several production phases and process operations. The Pixact online measurement systems for solid particles（including fibers, fines, impurities and precipitates）and gas content estimate enable the replacement of laboratory analyses with online quality monitoring and process control to optimize, e.g., energy consumption and chemical dosage. Pixact applications range from the early stages of pulp production to the water treatment facilities in the paper mill. In the following, four Pixact products and their applications in the pulp and paper industry are presented.
The Pixact Stock Monitoring PSM is designed for the analysis of impurities and color of flowing pulp suspension. The PSM system is installed directly on the process line. The system provides real-time measurement data without the need for preparing samples for analysis.
Pixact Particle Monitoring PPM technology can be used for the analysis of fiber characteristic in pulp and paper applications. Optimized analysis algorithms are developed for both traditional fiber and micro-fibrillated fibers. In online applications the PPM system is equipped with an automatic dilution station. The system produces real-time data on fiber size and morphology, such as: Fiber length and width, Fibrillation index, Fiber morphology（kinks and curls）and others.
The Pixact Particle Monitoring technology can be applied various filtrates and water treatment processes in pulp and paper production to produce in-depth measurement data on particle populations far beyond the capabilities of the traditional turbidity measurement. For example, in white-water analysis, the measurement system is equipped with a dilution unit and installed on the paper machine white-water circulation to analyse particle populations. The PPM classifies detected particles into categories, such as: Micro-particles, fines, fibers and flocs.
Pixact Bubble Monitoring technology is designed for the online analysis of bubble suspensions. The measurement system is applicable to any type of gas dispersion: It can be used from the detection of individual gas bubbles in liquid to the analysis of high gas content foams. Application in the Pulp & Paper industry include: detection or air in stock preparation, analysis of oxygen dispersion in delignification, analysis of the performance of flotation, analysis of foam quality in foam-laid forming and molded pulp.
Pixact Crystallization Monitoring technology can also be used to optimize its evaporation crystallization process and energy efficiency significantly.
