Metsä Fibre Restarts Its Joutseno Pulp Mill after Annual Maintenance Downtime

The exceptional length of the shutdown was due to extensive upgrades that were geared towards improving the Joutseno pulp mill's environmental performance.

July 7, 2014 - Metsä Fibre on July 3 said that it restarted its Joutseno pulp mill in Finland at the beginning of July after an annual maintenance shutdown of more than three weeks.

The exceptional length of the shutdown was due to extensive upgrades that were geared towards improving the mill's environmental performance. During the shutdown, the base and air system of the recovery boiler were replaced, which will improve the boiler's combustion management and, therefore, lead to a reduction in NOx emissions (nitrogen oxides), Metsä Fibre explained.

In addition, the chip silo and chip heating systems were upgraded according to the mill's current capacity. The project will significantly reduce any odour emissions from the chip silo. Chips are heated in the silo using pure steam that is generated using secondary heat from the boiler. Exhaust gases from the silo are burned off after processing, Metsä Fibre said.

The Joutseno mill has the capacity to produce 690,000 tons per year of softwood pulp.
