Valmet plans for increasing the sustainability of the pulp mill

BioCMPC project’s main targets are to increase the pulp mill’s sustainability and modernize the production technology. The project will include new control and environmental management measures across the mill. The project has been carefully designed based on CMPC’s mission to produce and market wood sustainably, pulp, paper, and tissue products of first-rate quality that are competitive, add value and create development opportunities for its employees and local communities.

“CMPC has chosen the most environmentally efficient and sustainable solutions. Valmet’s delivery offers our unique offering full benefits consisting of process technology, automation, and services. We will continue the excellent cooperation by improving the mill performance and including more industrial internet solutions combined with expert services on-site and remotely,” says Celso Tacla, Area President, South America, Valmet.

“We provide the mill with our latest technological innovations designed for high efficiency, which will allow the mill to be one of the most sustainable mills in Brazil with low environmental impact. The project will have a significant employment impact both for our engineering, production, and project execution in Brazil and the Nordics,” says Bertel Karlstedt, Business Line President, Pulp and Energy, Valmet.

“Valmet was chosen to be the key technology and automation provider for the BioCMPC project, and we are very happy to participate in this innovative and modern project. All equipment and solutions included in this project represent proven technology that provides better environmental performance and increased production efficiency.

Technical information about the delivery

Valmet’s delivery for the Guaíba pulp mill line 2 modernization will include rebuilding the pulp drying, fiber line, evaporation and white liquor plant, a new recovery boiler and new ash treatment, and extended distributed control system including advanced industrial internet features. Spare parts packages support technology delivery. The upgraded line is optimized for high reliability and performance with low environmental impact.

The upgrade of the pulp drying line will increase the drying and baling capacity and performance with the same high operational safety requirements that guide Valmet’s projects. The upgrade includes improvements to screening and drying, automatic tail threading, and an additional baling line.

The fiber line upgrade includes- 

  • Cooking plant technology update.
  • Fiber line improvements in brown stock and post-oxygen washing.
  • A new additional bleaching stage.

The upgrade allows the flexibility to minimize water usage and effluent generation, improving the sustainability of fiber lines and environmental KPIs.

The recovery island modernization includes a capacity increase of the recausticizing and lime kiln. An evaporation plant upgrades to eight effects, a new high-power recovery boiler with electrostatic precipitators (ESP), and ash treatment with Ash Leaching Duo technology. The recovery island modernization emphasizes high energy efficiency and low emissions. The collection and handling of the mill’s odorous gases are further improved with NCG upgrades across process islands.

The automation delivery includes Valmet DNA distributed control system, advanced process controls (APC) for selected process areas, analyzers, and online measurements.

The delivery is supported with extensive Valmet Industrial Internet (VII) services package with on-site and remote expert support.
