Development at Oulu Mill being evaluated by Stora Enso


A


feasibility study and an environmental impact assessment (EIA) is being carried


out by Stora Enso for a possible multi-million investment at its Oulu Mill on the Baltic coast of Finland. The feasibility study and the EIA are evaluating the potential for converting the paper mill to packaging board production. The study is expected to be


concluded by the end of 2018, and the EIA process is expected to take a minimum of six months. Currently, Oulu Mill has


capacity for 360,000 tons of chemical softwood pulp and two fine paper machines with capacity to make 1.08 million tons of woodfree coated papers. The potential investment would include a new chemi-thermomechanical pulp


(CTMP) plant, a brown-based cartonboard line with a capacity of 450,000 tons per year and a kraftliner line with a capacity of 400,000 tons per year. The conversion of Oulu Mill


would, if completed, enable Stora Enso to further improve its position in the growing consumer board and packaging product businesses and take a major step in its transformation. If the project goes ahead the


Pöyry to provide basic engineering for Finnpulp mill


Finnpulp has signed a basic engineering partnership agreement with Finland’s Pöyry Oyj for the €1.4-billion bio- production mill – expected to be the world’s largest using softwood pulp – planned for construction in Sorsasalo, Kuopio.


The bio-production mill will be the world’s first to utilise intelligent processes and artificial intelligence from the start, says Finnpulp. The basic engineering will take into account the requirements of optimisation in the digital ecosystem from raw material, supply chain and back


office to the quality and quantity of production. Pöyry Oyj’s basic engineering includes preparation of the construction stage of the mill’s processes, technologies and mill site layouts. This phase, which has now been started, will last to the first quarter of 2019, after


capital expenditure of about €700 million will be spread from 2019 to 2021. Stora Enso says this would fall within the group’s long-term capital expenditure policy of keeping capital expenditure into fixed assets approximately at the level of depreciation. The production on the new lines would start during 2020. Paper production at Oulu Mill will continue at least until early 2020.


which Finnpulp will have binding offers of bio-production mill’s main machinery, which enables the final construction decision to be made. The annual pulp production


capacity of the bio-production mill will be 1.2 million tons. It will also produce 60,000 tons of tall oil and one terawatt-hour (TWh) bioelectricity to the domestic power grid. The mill will use 6.7 million cubic metres of raw wood per year.


Sustainable energy initiatives at Nettingsdorf mill


Smurfit Kappa is having a recovery boiler and a pre- evaporation plant installed by Andritz at its Nettingsdorf kraftliner mill in Austria. The investments are part of Smurfit Kappa’s Future Energy Project, which involves the implementation of sustainable energy initiatives at the Nettingsdorf mill. Start-up of the pre-evaporation plant and the new recovery boiler is scheduled for mid-2019 and mid-2020, respectively. The HERB recovery boiler will


have a higher energy output while reducing emissions. Advanced features of the boiler include a smelt spout robot, an advanced soot-blowing control with a hanging parts’ weight change indicator, and a process simulator. To improve energy


efficiency at the mill, the new pre-evaporation plant will include Mechanical Vapor Recompression (MVR) technology to increase evaporation capacity at the mill. MVR units operate with very low


specific energy consumption and also produce clean condensate that will be reused in other mill processes to minimize consumption of fresh water. The key component in the press section is a new PrimePress X shoe press with a PrimeSteam VIB steam blow-box for profiling in order to achieve the required dryness. The first dryer group will be rebuilt as a single tier with new PrimeRun Jet and PrimeRun D stabiliser boxes. Ropeless tail threading will be added to the pre-dryer and after-dryer


sections. Between the dryer sections, a new PrimeFilm film press will be installed including contactless, high-intensity drying. Furthermore, the after-dryer section will be equipped with a new PM hood and a new dry broke pulper. At the end of PM2, a complete


new re-moisturizing system – PrimeSpray VIB – for both paper sides will be included. Finally, the moisturised paper will be wound using a complete new PrimeReel CenterDrive reeling system.
