The main objective of this thesis is to develop a systematic methodology for cost-effective thermal integration of production plant sections and the utility system of an industrial site. A production plant section is a subprocess of a production process that transforms materials into intermediate or end products. A production process is built up from a(More)
Simultaneous precipitation (SP) using iron sulfates in the secondary treatment of elemental chlorine-free (ECF) kraft pulp mill wastewater was studied. In short-term pilot plant studies phosphorus reduction was improved from 58% up to 81% by adding 10 mg(Fe)/L ferrous sulfate in the activated sludge (AS) process. The phosphorus reduction in full-scale(More)
The integration of different energy systems, e.g., industrial and municipal, is potentially important for the efficient utilization of energy. It is important that the tools for analysing this type of integration can handle the energy systems on different levels, e.g., regional, site, plant and process levels. In this work, a framework for investigating the(More)
