Bioske
Development of sub-processes of the bioproduct mill based on new measurement techniques
The new technical value of the project is the introduction of remote monitoring of new continuous measurements and the use of data sets analysis in the monitoring of fiber line operations and trial runs on fiber line, as well as the use of advanced modeling technologies in research activities.
An important part of the project is the strong involvement of the forest industry as a so-called “research platform” and project financier, so that the research results made in the Fiber Laboratory’s analytical and pilot environments can be scaled close to the industrial scale.
Project background
The Fiber Laboratory has long been carrying out studies to improve the operation of the various sub-processes of the bioproduct mill, as well as developing and implementing the new measurement and modeling technology needed in the studies. The activities in question have created an extensive knowledge environment and an industrial consortium.
A significant part of the project is new continuous measuring devices including advanced remote monitoring and management systems, their utilization in research, and implementation in understanding, improving and controlling the operation of sub-processes in bioproduct mills.
However, extensive experience of mill conditions is required for the operation and use of the model, especially in the main market area from mills manufacturing eucalyptus.
The best progress has been made in process and modeling expertise with regard to the oxygen phase and the washing of the surrounding brown stock. In addition to these, this project focuses in particular on the use of ozone in cellulosic delignification and the regulation of molecular mass. In addition, in relation to precipitates, we delve deeper into the mechanisms of precipitates in theory as well as in practice.
Key measures of the project
The project is divided into the following work packages, which strongly support each other:
WP 1. Oxygen delignification and brown stock washing
WP 2. Development of measurement technology
WP 3. Precipitations
WP 4. Ozone studies
Objectives
The primary objective of the Bioske project is to bring new measurements to bioproduct mills, which can be applied for research purposes to study the scientific and practical operation of processes, process optimization and control. In addition, the aim is to create new basic information, especially related to the operation of oxygen delignification and washing phases. Most importantly, bring the new measurements to remote monitoring and develop real-time on-line monitoring and analysis of data sets. The secondary goal is to improve the efficiency of processes, to produce information for the design and implementation of better processes, and to gain new measurement and modeling technology as well as gained know-how for the day-to-day operations of factories.
As a result of the project new expertise is created, research services and internationality of the Fiber Laboratory are developed as well as implementing cooperation between the Fibre Laboratory and the participating companies and strengthening the South Savo RDI and business activities.
