10 Stora Enso has invested 211 M in energy and environment for the continued development of the Skoghall Mill Goals for Energy 2005 To create a basis for the continued development of paperboard production To improve energy efficiency To reduce emissions to air and water Project scope Recovery boiler Evaporation plant CTMP evaporation plant Malodorous gas system Tall oil plant Rebuild of steam system and turbines Control room Conversion of the oil boiler into a biofuel boiler Fuel-handling system 10

11 Energy 2005 improves energy efficiency The more efficient use of energy and the increased use of bio fuel will reduce oil consumption by m 3 /a. The share of biofuels of Skoghalls fuel mix is expected to increase to 93 % in The degree of self-sufficiency in electrical power will increase from 15% to 35%, which is the equivalent to the production of MWh/a The Skoghall Mill is now one of the biggest producers of electrical power in region. 11

13 Energy 2005 a contribution to reduced climate impact Energy 2005 makes a considerable contribution to reducing fossil carbon dioxide emissions The change has an impact on a global climate context, where it is a large single contribution ton CO 2 /a Emissions of fossil CO 2-75 % The reduction corresponds to the emissions from cars in this region, where persons lives 0 Skoghall Mill 2004 Skoghall Mill est

16 Start up of the recovery area in autumn 2005 was a success Evaporation plant The plant was started at a stop in the pulp mill. After 6 hours liquor was delivered. Very good operational economy. Recovery boiler Flying start up. Pulp was produced during the start up. Board machines produced 2600 tonnes during start up day, which was a production record. More steam production than before resulting in a decreased oil consumption of 85 m 3 /d. 16

17 Start up of fuel handling and bio fuel boiler in summer 2006 was also a success! Fuel handling Good mix of different fuel types High availability Bio fuel boiler Good load regulation performance with bio fuel Good start up and high availability Emissions in level with expected 17

22 CTMP mill (mechanical pulp) (CTMP=Chemi Thermo Mechanical Pulp) Mechanical separtion of fibers in big refiners. The process gives % wood yield, but has a very high electrical power consumption. CTMP fibers provides bulk and by that stiffness in the board. Capacity t.p.a. Back 22

23 Sulphate pulp mill (chemical pulp) Chemical separation of fibers in the pulping process (cooking). The process gives 50 % wood yield, but chemicals and energy are recovered. The total strength of the fibers can be used in the board. Capacity t.p.a. Back 23

24 Chemical and energy recovery Back The recovery area in a sulphate pulp mill is a producer of energy as well as being a chemical plant for recovering cooking chemicals. 24
