UNIFORM NON-UNIFORMITY – WHAT CAN WE LEARN FROM CONTINUOUS OPERATION OF TMP REFINING PROCESS
A joint project is ongoing in Sweden and Norway with several parties with the goal to reduce energy input by 25％ at maintained quality levels in high consistency chip refining. The refiner used in the project is an 82″Metso CD refiner. The first step in this project, which is to establish references, is reported here. It is evident that similar pulp properties could be achieved over a wide range of specific energy input. Reference samples have been collected at 10 occasions in blow line and after latency chest respectively. 40 pulp samples have been analyzed as duplicates in five laboratories. Single tests can be misleading while duplicates improve the correlation between tested properties. Data reconciliation will further increase the accuracy in the tests. A great amount of the variations in the pulp and fiber properties could be explained by three independent common factors. The independent factors reflect fiber bonding, fiber length and shives content, respectively
