Metso Power Oy, located in Finland, began a new project in 2002 to design and build a new flue gas treatment operation within the new power plant for client, Kotkan Energia Oy, located in Kotka, Finland. Metso Power had to design the flue gas treatment plant to fit into the section of the new plant, which was pre-determined by Kotkan Energia. The fact that the location of the flue gas treatment plant was selected in advance, added to the complexity of the project. It was necessary to fit the equipment into a limited space.
