ANDRITZ to rebuild bleach plant at Stora Enso’s Skutskär Mill, Sweden

ANDRITZ has received an order from Stora Enso to rebuild bleach plant no. 4 at its Skutskär Mill in Sweden. Start-up is scheduled for the second quarter of 2023.

The investment in new bleaching technology will increase the capacity of the mill and support Stora Enso’s ambitious climate targets. In addition, it will improve operational performance, enhance the overall efficiency of mill maintenance and thus reduce the site’s carbon footprint.

Delivery is on EPC basis and includes the installation of two COMPACT PRESS wash presses, a new reactor, an effluent fiber filter, and MC equipment – all from ANDRITZ.

The COMPACT PRESS wash press is characterized by its small footprint and high availability, including extremely good washing efficiency, thus ensuring high-quality production and highest pulp cleanliness.

For added sustainability and circularity, the mill will reuse the Stora Enso Oulu mill’s bleaching reactor (also supplied by ANDRITZ) and some of the mixers there.

ANDRITZ was also selected to replace an existing wash filter in Fiberline 3 after the brown stock screen room with a second-hand press from the Altri Celbi mill, previously owned by Stora Enso.

This order once again confirms the excellent business relationship between ANDRITZ and Stora Enso.

The Skutskär mill has an annual production capacity of 540,000 tons and produces fluff, hardwood and softwood kraft pulp.
