Metso to Deliver Lignin Separation Technology to Domtar's Plymouth Mill
Comment Print
Helsinki, Finland, 15 December 2011 -- Metso will supply the world’s first commercial installation of LignoBoost technology to Domtar in North America. The equipment will be intergrated with the Plymouth, North Carolina, pulp mill. The process separates and collects lignin from pulping liquor. This order is an important breakthrough for Metso’s patented technology. The value of the order is not disclosed.

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 ... will allow pulp mills to have a new more profitable value stream from a product that was traditionally burned in a recovery boiler,” said Gene Christiansen, general manager – Business Development Innovations at Metso’s Power Business Line for North America in Charlotte, North Carolina.

The LignoBoost project is based on the 24 ton per day demonstration plant in Bäckhammar in Sweden. The Bäckhammar plant ha been owned and operated by Innventia since 2006. In 2008, Metso acquired the technology from Innventia and the companies have since then been working together on the commercialization of the process.

The plant will be in commercial operation at Plymouth in early 2013.The order is included in the Energy and Environmental Technology’s fourth quarter 2011 orders received.
