Valmet receives order from Holmen for softwood line rebuild at Iggesund mill

Valmet will deliver equipment and services for a rebuild of the soft wood pulp line at Holmen‘s Iggesund mill in Sweden. The rebuild will improve production stability, cut variable costs and increase pulp production capacity by 15 percent equally to 50,000 tonnes. The works will be implemented in two stages during 2015 and 2016.

The order is included in Valmet’s first quarter 2015 orders received. The value of the order will not be disclosed.

“We have a good experience since we have had Valmet presses in our mill for many years. This rebuild will eliminate bottle necks in the process and increase pulp capacity. We will also cut variable costs which will strengthen our competitiveness”, says Olov Winblad von Walter, Mill Director, Iggesund.

“This rebuild is the first step towards a press based bleach plant. The high outlet consistency makes the process easier to control and the volume of effluent will be less than for washers with lower discharge consistencies. Also water and chemical consumption will be minimized. We are looking forward to a good co-operation in this project”, says Mikael Gustafsson, Sales Manager, Valmet.

 Technical information about Valmet’s delivery

The scope of the Valmet delivery includes main machinery, basic engineering and erection. In the first stage, two pressure diffusers will be rebuilt, one in the cooking plant and one in the brown stock washing, where also a new TwinRoll press, will be installed. In the second stage, the oxygen delignification stage will be extended into a two-stage OxyTrac system, which will make it possible to still reach lower kappa numbers in case of a further production increase. In the bleach plant two new TwinRoll presses will be installed.
