Smooth installation of TwinRoll press during annual shutdown


a TwinRoll Evolution press supplied by Valmet was installed. Lars Harrysson, project leader


D


at Södra, said that the installation and commissioning were highly successful, and that the schedule was maintained throughout the project. “Everything has worked out, and everyone has done their utmost to get the new press installed and running,” he said. Södra Cell Mönsterås is Södra’s


biggest pulp mill with a capacity of 750,000 tonnes per year. In


addition to electricity, the mill delivers district heating to the city of Mönsterås and to Södra’s sawmill in the area. The mill also supplies tall oil for biodiesel. Södra is in a period of substantial investments and plans to invest more than €30 million in the pulp mill in Mönsterås in the


two years to the end of 2016 to improve energy usage and increase productivity. Olof Hellström, one of Södra’s


project managers, added: “The new wash press will play an important role in our process to secure a grade of pulp that meets customer requirements and to


First OptiConcept M board making line for North America


Pratt Industries recently started up its new US container board mill at Valparaiso in Indiana when the PM16 production line came on stream. Built on a greenfield site, the mill


is first in North America to have an OptiConcept M machine from Valmet installed. Anthony Pratt, global chairman of Pratt Industries, commented:


“PM 16 is at one of the industry’s most efficient paper mills, employing 120 people to make 370,000 tons a year, twice the productivity of many competitor mills. It is the world’s most environmentally-friendly paper mill and a showcase for the latest in 21st century paper-making technology.” The Valmet OptiConcept M


board making line is designed to use less water, electricity and raw materials. “That’s important not only for our environment but also for our customers who realize the importance of sustainable packaging,” added Pratt. Pratt Industries is America’s fifth-largest corrugated packaging producer and the world’s largest, privately-held 100 per cent


The Valmet OptiConcept M containerboard production line was started up in October for Pratt Industries at the Valparaiso mill in Indiana


recycled paper and packaging company, with more than 5,200 employees. Since its founding 25 years ago it has built production facilities in more than 20 states.


Bleaching system upgrade for Rottneros pulp mill


A new high-consistency bleaching system is being supplied by Valmet to the Rottneros pulp mill in Sweden. It is the first step in a larger


rebuild project at the mill, called Agenda 500, with the long-term goal of increasing both availability and production volume of the


January/February 2016


two Rottneros pulp mills to reach a capacity of 500,000 tons per year.


“In our investment project we


aim to increase capacity and lower our chemical consumption. We have had a long and good relationship with Valmet over the years, which is one of the reasons


for choosing them as supplier,” says Nils Hauri, production manager at Rottneros mill. Valmet will supply the machinery and provide erection, training, commissioning and start- up services. The bleaching system consists of a chemical mixer and a bleaching tower, two washing


stages with screw presses and pumps. This project aims to lower the peroxide consumption, increase capacity and keep maintenance costs to a minimum. Rottneros produces market pulp with an annual output of just under 350,000 tonnes of pulp, produced at two mills in Sweden.


uring the yearly shutdown at Södra Cell’s Mönsterås pulp mill in Sweden,


achieve improved availability.” The installation was carried out in September last year. Mikael Johansson, project manager at Valmet, commented: “The shutdown in Mönsterås was well planned which created the best possible conditions and enabled the efficient installation. Slightly more than one day after the start-up, the press was up and running in nominal production of soft wood pulp, with a dryness that was well above the promised. The training was an important piece in the success. Committed and interested operators enabled a quick knowledge transfer.”
