Screening, Cleaning and Bleaching - Mechanical Pulps - PPE122
Credits: 4 (Independent Study)
This course deals with the technical aspects of pulp purification and includes the processes of pulp screening, pulp cleaning and pulp bleaching. The technologies of each of these types of processes will be investigated though the major emphases will be placed on bleaching. Screening requirements, equipment and basic theories will be covered. Process conditions, fundamental flow diagrams and material balances will be studied. Removal of contaminants from pulp by cleaning systems will be studied in terms of equipment and process conditions. Pulp bleaching for mechanical pulps will be studied in terms of basic theories, process types, conditions and process flows.
