1. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability
Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER
2. Influence of Polymeric Multilayer Treatment on Out-of Plane Properties of CTMP-Based Paperboard
Sammanfattning : .... LÄS MER
3. High temperature CTMP from birch
Sammanfattning : This thesis is intended to contribute to understanding of the chemithermomechanical pulping of birch intended for high freeness grades. It focuses on the effects that conditions during pre‐treatment, i.e. LÄS MER
4. Process modelling in pulp and paper manufacture : Application studies with aspects of energy efficiency and product quality
Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, board and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER
5. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping
Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER
