International technology Group Andritz received an order from Swedish pulp and paper manfufacturer Billerud AB to supply a flue gas treatment system for its Gruvön mill in Sweden.

The system will allow the mill to increase the output of its soda recovery boiler while at the same time reducing emissions. The recovered soda is reused in the pulp manufacturing process.

Andritz will supply an electrostatic precipitator (ESP) including its proven switched integrated rectifier technology (SIR) for maximum operational efficiency. Andritz has won more than 20 ESP lines since integrating this product into its portfolio in 2021.

The new precipitator will be installed in addition to the two existing ESPs, allowing Gruvön mill to increase the capacity of its soda recovery boiler by over 30% while keeping particulate matter emissions well below 15 mg/Nm3. The Andritz ESP solution will enable the mill to continue its profitable operations while complying with the strict local environmental regulations.

Andritz's scope also comprises all auxiliaries for ESP connection as well as mechanical erection, insulation, supervision of construction, and commissioning. Handover is scheduled for the Q2 2024.

Billerud is a globally leading company in superior paper and packaging materials. The company operates a total of ten production units, of which six in Sweden.

Andritz Pulp & Paper provides sustainable technology, automation, and service solutions for the production of all types of pulp, paper, board and tissue.
