ANDRITZ: upgrades tissue machines at Sofidel, Sweden, to use bio-sing gas for drying – a first in the tissue industry
In order to be able to replace the heating process from the LPG (Liquefied Petroleum Gas) that is currently used to burn bio-gas instead, the burners at PM3 and PM4 in the Kisa mill will be replaced and the combustion chamber in the hood of PM3 will be replaced. upgraded by ANDRITZ Novimpianti. This will ensure a uniform flow of gas and thus enable efficient and consistent drying of the tissue. When the upgrade is complete, PM3 will use 100 percent biosyngas for paper drying, while the PM4 burner will be partially powered by biosyngas.
This investment is part of Sofidel’s goal of reducing CO emissions by 8,500 tonnes annually. The biosyngas used for the heating process will be generated in a thermochemical conversion plant at the Kisa plant, using locally produced chips as biofuel.
ANDRITZ Novimpianti’s role at Kisa is based on its many years of experience in air and energy systems for tissue, paper and board. ANDRITZ Novimpianti’s CEO Luca Linari says: “This is the first time that bio-singing gas will be used to dry paper and represents an important step towards making the entire paper industry more sustainable.. And ANDRITZ is very proud to support Sofidel in its initiative to reduce CO₂ emissions. “
Sofidel’s chief technology officer Davide Mainardi says: “The adoption of bio-singing gas in Kisa is an important part of our sustainability roadmap. This initiative with ANDRITZ Novimpianti, Meva Energy and the University of Pisa provides concrete benefits that will yield results in a relatively short time frame. It will also help to give us confidence that our interim target of a 40 percent reduction in CO₂ emissions by 2030 compared to the base year 2018 are possible with technology that is already available. ”
