Valmet to supply cooking and fiberline to Sun Paper’s Beihai mill in China

Finland-headed forest industry and energy technology provider Valmet Oyj has announced that it will supply cooking and fiberline to Guangxi Sun Paper Co., Ltd’s new Beihai mill in China. The pulp mill will have a capacity of 800 000 air-dried tonnes (adt) per annum of bleached hardwood kraft pulp.

The Guangxi Sun Paper greenfield hardwood pulp and paper mill under construction in Beihai, China will eventually have a total pulp and paper capacity of 3.5 million tonnes annually.

Sun Paper is one of the subsidiaries of Shandong Sun Holdings Group, which was founded in 1982. Currently Sun Paper has two mills in China’s Shandong province. The company also operates a pulp mill in Laos with a 300 000 tonnes per annum dissolving pulp line and a 400 000 tonnes per annum year recycled pulp line.

In July 2019, Sun Paper established a wholly-owned subsidiary, Guangxi Sun Paper, to build an integrated pulp and paper mill in Beihai.

Valmet’s delivery is part of Sun Paper’s new greenfield mill in Beihai, which will eventually have a total pulp and paper capacity of 3.5 million tonnes annually.

Our overall target of the project is to build a world-class mill. We wanted to choose advanced and reliable technology that has little impact on the environment at the same time as it performs with high quality and efficiency and has low operating costs. We chose Valmet because they met our goals well in this project. We have also had a good collaboration in all previous projects, said Yanjun Cao, Vice General Manager, Sun Paper.

The order, the value of which has not been disclosed, complements the fine paper machine, automation, and recovery boiler order which Valmet announced in April 2020.

We had many discussions with the customer, and we managed to offer a concept that fits their needs well with a tight delivery schedule and long-term cooperation. All our earlier pulp mill references were also contributing factors to this important order, said Xiangdong Zhu, Area President, China, Valmet.

The scope of Valmet’s supply includes main equipment and process design for continuous cooking, deknotting, screening, brown stock washing, oxygen delignification, and three-stage elementally chlorine-free (ECF) bleaching. Corresponding spare parts and site services are also a part of the scope.

The cooking and fiberline will feature leading process technology, including the latest developments in our continuous cooking technology, to reach excellent efficiency in energy and raw material utilization. A high end-product quality with low effluent flows and high environmental performance will be secured with the latest generation of TwinRoll wash presses throughout the fiberline in combination with Valmet’s screening, oxygen, and bleaching technology, said Eva Engelfeldt, Senior Sales Manager, Fiber Processing Business Unit, Valmet.
