A Valmet-delivered TwinRoll Evolution press was successfully installed at Södra Cell‘s Mönsterås pulp mill in Sweden during the yearly shutdown in the end of September. This is the 85th TwinRoll Evolution press Valmet has delivered since the model was launched in 2009.
“The new wash press will play an important role in our process to secure a grade of pulp that meets customer requirements and to achieve improved availability,” says Olof Hellström, one of Södra’s project managers.
Lars Harrysson, project leader 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,” says Harrysson.
“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,” says Mikael Johansson, Project Manager at Valmet.
