Aker Kvaerner wins contract for board mill in Sweden

Dec. 15, 2003 -- Kvaerner Power has signed a contract for the supply of equipment, machinery and services to Stora Enso's Skoghall Mill in Sweden, worth a combined total of more than EUR 100 million.

Stora Enso is modernizing its Skoghall board mill located in Central Sweden to ensure the cost effective production and to achieve world class environmental and energy efficiency performance.

Kvaerner Power will supply a new RECOX™ recovery boiler rated at 2,200 tons dry solids/day.

The mill's present evaporation plant will be replaced with a new EVAPSTM evaporation plant from Kvaerner Power. It is designed for evaporation of black liquor and liquor from the CTMP process and the total evaporation capacity will be 750 tons of water/hour. The plant will use TUBEL® technology as well as conventional falling film technology.

Skoghall mill's strong odorous gases will be burned in Kvaerner Power's NCG treatment system (Non-Condensable Gas) whereas weak gases will be burned in the new recovery boiler.

The mill's existing oil fired boiler will be converted to a bubbling fluidized bed boiler to burn biofuels such as bark, forest residue and sawmill waste. The new power boiler will produce energy for the mill's processes with a thermal capacity of 136 MW.

The recovery boiler and evaporation plant will be completed by autumn 2005 and the power boiler conversion will be commissioned in the summer of 2006.

The supply involves the joint resources of Kvaerner Power's units in Sweden and Finland.
