Abstract [en]

This thesis has been carried out on behalf of SCA Packaging Munksund. The company had problems with their sealingwater which has not held the requested quality, further there were problems with large consumption of raw water. The aim of the project was to get an overview of the management system for sealingwater in paper mill, as well as to find a solution to the sealingwater problem. With help of quantitative method the project was split up into two parts, investigation and action, this to achieve its purpose. The results of the investigation gave a sketch of sealingwater system and a compilation of all the devices that are connected to this. The results of the water analysis showed that there were unnecessarily large water consumption, high water temperatures and large amounts of pollutants in the sealingwater. A number of solutions to the problems were developed. Through optimization of the water flow a reduction in water consumption up to 83% can be achieved. If self-cleaning automatic filters were installed, it would increase purity of the sealingwater. A reduction of sealing water temperature from the current (46° C) to 20° C would give a reduced energy consumption of about 16 000 MWh/year.
