LD Celulose puts into operation new pulp mill in Brazil

LD Celulose S.A, a joint venture between the Austrian company Lenzing and the Brazilian company Dexco, invested about $1.3 billion in a 500,000 tonne/year dissolving wood pulp mill in the Triângulo Mineiro region in Brazil. Valmet delivered the key process islands and integrated automation solutions for the mill. The equipment operations and the production ramp-up in the new mill have now successfully started.

Valmet delivered the project with extended scope of supply. Detailed engineering for the project was started in the beginning of 2020 and the installation works at the site in the beginning of 2021.

Valmet's complete delivery included a fiber line, a pulp drying and baling line, an evaporation plant, ash crystallization, a white liquor plant, mill-wide automation system, analyzers and training simulators for all process areas.

The mill-wide automation system, Valmet DNA, stands out with its innovativeness being built on the latest virtualization technology, allowing a completely new way to operate the mill and integration with analyzers.

Valmet Operator Training Simulator (OTS) will be used in all process islands, from the beginning to the end of production, with a total of 14 process areas. An innovative fact of the project is that its wood handling area is the first in Brazil to use OTS technology. Another highlight is the presence of simulators for the areas of water treatment, water treatment for boilers, effluent treatment and turbines, commonly little explored in the OTS.

Valmet is a leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries.
