Valmet and CMPC have signed a letter of intent (LOI) for Valmet to deliver key technology for the BioCMPC project. The target of the project is to increase the production capacity of the Guaíba pulp mill’s line 2 from 1.5 million ADt/y (air dry tonnes per year) to 1.85 million ADt/y. The modernization is expected to start operation in the 4Q 2023.
Valmet and CMPC target to finalize the contract during October 2021.
This expansion project, BioCMPC, targets both to increase the production capacity of the Guaíba mill and also improve the environmental performance with for example increased production of renewable electricity and minimized water usage in pulp production process.
Valmet’s delivery for the Guaíba pulp mill line 2 modernization will include rebuild of the pulp drying, fiberline, evaporation and white liquor plant, a new recovery boiler and new ash treatment, extended distributed control system including advanced industrial internet features. The technology delivery is supported by spare parts packages. The upgraded line is optimized for high reliability and performance with low environmental impact.
The pulp drying line upgrade will increase the drying and baling capacity and performance with the same high operational safety requirements that always guide Valmet’s projects. The upgrade includes improvements to screening and drying, automatic tail threading and an additional baling line.
The fiberline upgrade includes cooking plant technology update, fiberline improvements in brown stock and post oxygen washing and a new additional bleaching stage. The upgrade gives flexibility to minimize water usage and effluent generation improving the fiberline sustainability and environmental KPIs.
The white liquor plant upgrade includes capacity increase of the recaustisizing and lime kiln. The modernized lime kiln electrostatic precipitator (ESP) and lime mud disc filter will ensure low emissions.
