ANDRITZ will convert the mill’s continuous digester to Downflow Lo-Solids cooking technology and add a TurboFeed chip pumping system to improve the feed to the digester, and will add a vapor reboiler to further reduce odorous emissions. ANDRITZ will also deliver a pressure diffuser washer for the brownstock area.

This upgrade is a follow-up order to the recovery boiler that was delivered by ANDRITZ and started up successfully at Frantschach in 2013. Mondi’s investment will help to improve the use of resources and further increase the mill’s energy efficiency and competitiveness.
