1. Displacement Washing in the Sulfate Pulp Mill
Sammanfattning : Displacement washing is an operation in which it is possible to wash solid-phase particles with a minimum of water. In a sulfate pulp mill, the main application is the pulp washing, but lime mud washing also occurs in the chemical recovery. The washing consumes a great deal of water. LÄS MER
2. Energy efficiency measures in a kraft pulp mill converted to a biorefinery producing ethanol
Sammanfattning : Large scale, sustainable production of ethanol biofuel will most likely require commercialization of processes using lignocellulosic raw materials. To date no commercial plant exists however, due to the difficulties in reaching production costs that can compete with 1st generation ethanol and fossil fuels. LÄS MER
3. Analysing different technology pathways for the pulp and paper industry in a European energy systems perspective
Sammanfattning : For the pulp and paper industry (PPI), earlier research has shown that there are many technology pathways, proven and new, available for improvement of energy efficiency and additional sales of (new) products. Some pathways can only be implemented in kraft mills, e.g. black liquor gasification (BLG), but some can be implemented industry-wide, e. LÄS MER
4. Bonding Ability Distribution of Fibers in Mechanical Pulp Furnishes
Sammanfattning : This thesis presents a method of measuring the distribution of fiber bonding ability in mechanical pulp furnishes. The method is intended for industrial use, where today only average values are used to describe fiber bonding ability, despite the differences in morphology of the fibers entering the mill. LÄS MER
