International technology Group ANDRITZ has received an order from Stora Enso to supply a new sludge dewatering line for thickening and dewatering of fibrous sludges for the board mill Skoghall, Sweden. With a capacity of up to 750,000 tons per year, Skoghall is one of the world’s largest producers of liquid packaging board. Start-up of the new ANDRITZ plant is scheduled for April 2014. The order comprises delivery of a gravity table and a sludge screw press to process up to 50 tons of mixed sludge per day, thus significantly increasing the capacity of the existing sludge dewatering plants. The sludge to be dewatered consists of a mixture of fibrous and biological sludges, as well as chemical sludges from the mill’s CTMP line. The ANDRITZ sludge screw press dewaters the mixed sludge to the highest possible dryness that can be achieved today by mechanical means. In order to meet the new process requirements resulting from this plant extension, Stora Enso’s order also includes the rebuild of an existing ANDRITZ belt press supplied in 1989. Due to the higher final dryness achieved through the dewatering lines in the future, Stora Enso Skoghall will be able to feed a higher amount of dewatered sludge to the power boiler and operate it with greater energy efficiency. http://www.andritz.com/group/gr-news/gr-news-detail.htm?id=25712 Project Name ANDRITZ to supply new sludge dewatering plant to Stora Enso, Sweden Location Sweden Commence 2013 Completion -NA- Estimated Investment -NA- Capacity -NA- Key Players ANDRITZ
