GRAZ, 13-Nov-2017 — /EuropaWire/ — International technology Group ANDRITZ has received an order from Iggesund Paperboard AB, a member of the HOLMEN GROUP, to supply a new evaporation plant and rebuild an existing evaporation plant for the pulp mill in Iggesund.

Start-up of the new plant is scheduled for the second quarter of 2019 and of the rebuild for the fourth quarter of 2019.

The new 7-effect high dry solids evaporation plant will have a capacity of 350 t/h evaporated water. It will replace an old ANDRITZ evaporation line from the 1970’s and significantly enhance energy efficiency at the Iggesund mill. The state-of-the-art technology of the evaporation plant will improve the cleanliness of the condensates produced, which are reused in other processes in the pulp mill.

The existing evaporation plant will be rebuilt and upgraded to 220 t/h with modern ANDRITZ lamella technology in effects 1 and 2 in order to meet and exceed the plant’s original design data.

ANDRITZ’s lamella technology ensures the desired steam economy at all times, reduced energy consumption by circulation pumps, as well as higher black liquor concentration and stability, thus leading to increased and stabilized power production in the recovery boiler. It also provides optimized vapor condensate quality that contributes towards lower energy and chemical consumption. This reduces the mill’s operational costs. In addition, shorter and fewer washing cycles enhance the overall availability and production.

Olov Winblad von Walter, Mill Director at Iggesund mill: “The clear advantages of ANDRITZ’s lamella technology as well as the excellent cooperation with ANDRITZ in previous projects were decisive factors for Iggesund Paperboard to award the order to ANDRITZ.”

Iggesund Paperboard is part of the Swedish forest industry group Holmen, one of the world’s most sustainable companies and listed in the United Nations Global Compact Index. The Iggesund Mill produces high-quality bleached paperboard under the brand name Invercote™, sold in more than 100 countries.
