Metsa Fiber位于芬兰Joutseno浆厂世界最大的单一多硫化物制浆生产线已经开机。该生产线由安德里茨提供多硫化物制备技术和提高针叶木浆产能的蒸煮器改造技术。据Joutseno浆厂总经理兼项目经理Risto Joronen介绍,采用多硫化物蒸煮液能够提高浆料的某些特性,最终惠及纸厂用户。好处之一是降低磨浆机能耗,从而降低纸厂的运营成本。由于浆料中含有一定量半纤维素,在一定程度上也能增强纤维间的结合力。Joutseno浆厂通过改造也增加 Metsa Fiber’s largest single polysulfide pulping line in the Joutseno pulp mill in Finland has been started. The production line consists of ANDRITZ’s polysulfide preparation technology and digester modification technology to increase the production of softwood pulp. According to Risto Joronen, general manager and project manager of the Joutseno pulp mill, the use of polysulfide cooking liquor can improve certain characteristics of the pulp and ultimately benefit mill users. One of the benefits is to reduce the energy consumption of the refiner, thereby reducing the mill’s operating costs. Since the slurry contains a certain amount of hemicellulose, the binding force between the fibers can also be enhanced to some extent. Joutseno pulp mill also increased through renovation
