Separation of a portion of the mill's total lignin production off-loads the recovery boiler and allows an increase in pulp production capacity. The lignin recovered will be used for internal and external applications.
"This project is a potential game changer for the pulp and paper industry because it will allow pulp mills to have a new, more profitable value stream from a product that was traditionally burned in a recovery boiler," says Gene Christiansen, GM–Business Development Innovations at Metso's Power Business Line for North America in Charlotte, N.C.
The LignoBoost project is based on the 24 tpd demonstration plant in Bäckhammar in Sweden. The Bäckhammar plant is owned and operated by Innventia since 2006. In 2008, Metso acquired the LignoBoost Technology from Innventia and the companies have since then been working together on commercialization of the process.
