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
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

Sammanfattning : Large scale, sustainable production of biofuels will require commercialization ofprocesses using lignocellulosic feedstocks. These processes are still notcompetitive with existing pathways, however. The competitiveness oflignocellulosic biofuel production plants could potentially be improved if theywere integrated with already existing facilities. LÄS MER
5. Analysing strategic energy-related investments in process industries : applied studies at a pulp and board mill
Sammanfattning : The potential to reduce energy demand in industrial applications is often substantiaL Since energy cost represents a considerable share of the value added in several categories of process industries, a great potential exists for cutting costs through investment, for instance in energy efficiency improvements. However, industrial energy systems form complex relations not only within the industrial unit, but also in the interaction with their surroundings. LÄS MER
