There will be 14,000 tons of CO2 emissions per year that the pulp mill will eliminate by replacing oil with electricity.

Norway.- Vafos Pulp, a Norwegian producer of unbleached pulp for cardboard manufacturing, will switch its oil-fired intensive drying process for electricity, greatly reducing the plant’s carbon emissions. The company will replace a nine megawatt (MW) oil-fired boiler with electric heaters, controlled by ABB technology.

The Kragerø pulp mill, which produces 80,000 tons of pulp each year, will remove 14,000 tons of CO2 annually from mid-2022. That’s the equivalent of the annual emissions of about 7,000 combustion engine cars.

New air heaters require a significant amount of energy and managing them is key to keeping the plant safe, operating efficiently and minimizing downtime. They are regulated by ten ABB DCT880 power controllers to manage the power supplied to the electric heater elements.

The controllers are container-mounted and use a power optimizer feature to create a constant load that minimizes interruptions to the local power grid. The integration of the systems was a joint effort between ABB and Norwegian system integrators EAS and Actemium Electro.

DCT880 power controllers are a long life product and contain the latest interface and control technology. This will allow operators at the Kragerø plant to control the drying process more precisely than when using oil. The switch to electricity also means the facility will no longer need on-site oil storage.

“The era of burning heavy oil in Norway is over,” says Roar Paulsrud, CEO of Vafos Pulp. “Customers expect us to be part of the green transition with sustainable production. It is also important that our industry helps reduce emissions here in Norway.”

“The project in Kragerø is a great example of how organizations can decarbonize by using modern electrical alternatives,” says Lars-Fredrik Mathiesen, director of ABB Motion in Norway. “As Norway’s grid is being powered almost entirely by renewable energy, moves like this one by Vafos Pulp lead the way for others in the industry, and will be key to achieving the government’s goal of cutting CO2 emissions in half. by 2030”.
