Purpose and goal
The goal of the project is to develop, evaluate methodologies that allow for the analysis of the entire produced area in paper or board production. The methodologies are based on visual and infrared imaging. The data will be synchronised and converted into product property maps, which are then used to analyse the property variation. This allows for the identification of the origin of the variation.
Expected results and effects
Three methods of analysis were developed based on IR-measurements and data from six paper and board mills. Three applications were identified: process diagnostics to reduce variations, new method to reach the correct operating modes more quickly, and more accurate quality classification over the entire area produced. The first two improve product quality and process efficiency, thus reduce resource use. The latter enables new business based on information, to be used by customers, for easier and more resource efficient conversion, printing and packaging production.
Planned approach and implementation
Six mill trials have been planned and executed by a consortium consisting of RISE, six mills producing different products, ABB and KTH. Under collaborative expertise on surface inspection and quality control systems as well as signals and systems, methodology was developed to process and synchronize data and convert it into property maps. The resulting methodology was applied to varying degrees for the various mills, depending on their basis. Respective industry participants have since been given the opportunity to analyze the conditions for further implementation.
