METSO DELIVERS NEW INNOVATIVE FLOTATION TECHNOLOGY TO KERÄYSKUITU IN FINLAND

Metso Corporation's Fiber and Paper Technology business area Valmet and Keräyskuitu Oy have signed a delivery contract covering a new flotation system for the Keräyskuitu deinking plant in Kotka, Finland. The start-up of the new system is scheduled for year-end 2000.

The new system is designed to use old newspapers (ONP) and magazines (OMG) as main raw materials for producing pulp for newsprint and magazine paper producers. The capacity of the line is 340 ADMT/D.

The heart of the new Keräyskuitu flotation system is the new innovative Valmet flotation cell. The new system includes two innovative primary MuSTCell 105 units with one secondary MuSTCell 30 unit. Prior to the supplier selection, Keräyskuitu operated a pilot MuSTCell unit for several months with excellent results. In particular, the air dispersion operation principle represents a new solution differing from the other systems existing in the market. Additionally, the MuSTCell utilizes the specific weight difference of the pulp in internal flows instead of pumping.

Valmet's delivery is a complete turn-key project, including all key flotation system equipment and process piping, instrumentation, electrification, mechanical engineering, training and start-up services.

The order represents a breakthrough for Valmet into the deinking market. With this new technology, Valmet`s range of recycled fiber and deinking technologies enables deliveries of complete lines.

Keräyskuitu Oy is owned by Stora Enso Oyj, Myllykoski Paper Oy and Metsä-Serla Corporation.
