CTS Engtec upgrades pulp dryer at Stora Enso's Kaukopää mill in Imatra, Finland

KOUVOLA, Finland, Aug. 25, 2011 (Press Release) - The KU 1 pulp drying machine in Stora Enso's Kaukopää plant in Imatra is being upgraded, with the aim of improving the fibre balance in the production of the Imatra plant. The productive capacity of the drying machine will be increased by about 30% for all pulp types.

CTS Engtec is overseeing the planning of the upgrade process. The project includes process, plant, electric, automation, heating and ventilation, and structural design as well as the project management for the design stage.

The targets of the project include changes to pulp preparation and the wire and press sections, raising the steam pressure of the drying cabinet, the improvement of recirculation fans and ventilation, modification to the sheeter, upgrading of the wrapping machine, modification to the dropping device, updating of the automation system, improvement to the baling line, and upgrading of the bale management and bale storage systems.

The increased drying capacity in turn enables the Imatra chemical pulp mill to improve its overall capacity and minimize production and quality inconsistencies. A more uniform quality of chemical pulp contributes to the reduction of the grammage of the final product. An increase in chemical pulp production will improve the energy consumption of the whole company.

The upgraded pulp dryer will be in use at the end of 2011.
