ANDRITZ white liquor plants

Improved efficiency means a lower carbon footprint. How can this be achieved in the white liquor plant? Improved efficiency leads to less overall energy use which in turn means the lowering of carbon footprint. In the search for improvements in white liquor plant operations ANDRITZ has developed a uniquely simplified and ultimately more efficient technology, LimeDry-H, for improved lime mud feeding.

Biomass Gasification for Lime Kilns — Going fossil fuel free is an urgent sustainability topic that has become even more critical due to the current global energy crisis. It is clear we must reduce our dependence on fossil fuel.

We have heard a lot about the possibility of “foreseeing digitally” when it comes to processes in the pulp and paper industry, but now it’s actually happening. Metsä Fibre’s Äänekoski bioproduct mill in Finland is predicting the future utilizing the latest digital technology from ANDRITZ for its white liquor plant.

Increasing capacity of the lime kiln is time consuming and costly as it usually involves the lengthening of the existing kiln shell, or even a replacement with a larger diameter. ANDRITZ experts have approached the challenge from a completely different angle, and now a capacity increase of up to 40% can be achieved at much lower costs.

The pulp making process hasn’t inherently changed over the years; however, ANDRITZ has had a lot of success with reinventing processes and technology in and around mills to increase capacity, improve quality, and cut operating costs. The LimeWhite-H White Liquor Disc Filter is another game-changing development.

The largest engineering projects northern Sweden has ever seen was completed recently with the doubling of capacity at SCA Östrand’s softwood kraft pulp mill. The project – named Helios after the God of the Sun in Greek mythology – is now setting a new global benchmark in high-performance pulp production. ANDRITZ supplied some of the latest key technology to the completely rebuilt mill.
