Valmet and CMPC have signed a letter of intent (LOI) for Valmet to deliver key technology for the BioCMPC project. The project’s target 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 fourth quarter of 2023.

Valmet and CMPC aim 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 the pulp production process.

“Valmet delivered the CMPC’s Guaíba mill line 2 in 2015, and the mill has been a showcase for many of our technologies. Over these years, we have introduced value-adding industrial internet solutions and offer our expert mill maintenance services. To be chosen as the main partner for this remarkable project reinforces Valmet’s commitment for a more sustainable future,” says Celso Tacla, area president, South America, Valmet.

“With this project we will continue delivering the best technology available combined with leading automation and industrial internet solutions for efficient and even more sustainable pulp production. This delivery will feature our latest technology to lower water usage, reduce emissions and eliminate odorous gases. Our experts will support optimizing the mill performance both onsite and remotely,” says Bertel Karlstedt, business line president, Pulp & Energy, Valmet.

Technical information about the Valmet delivery

Valmet’s delivery for the Guaíba pulp mill line 2 modernization will include rebuilding 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. 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 fiberline upgrade includes-

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

The upgrade gives the flexibility to minimize water usage and effluent generation, improving the fiberline sustainability and environmental KPIs.

The white liquor plant upgrade includes the capacity increase of the recausticizing and lime kiln. The modernized lime kiln electrostatic precipitator (ESP) and lime mud disc filter will ensure low emissions.

The evaporation plant will be upgraded to process 2,000 t water per hour. The eight-effect design provides a high steam economy and features a robust and reliable Valmet Tubel design. Improved condensate treatment will lower the water consumption of the mill.

The new recovery boiler will have a design capacity of 1,900 tds/d (tonnes dry solids per day) and will feature several high-power features for low energy consumption and high steam generation. The delivery also includes electrostatic precipitators (ESP) tailored for recovery boiler conditions. The recovery boiler ash will be treated with Ash Leaching Duo technology offering easy operation and improved leaching efficiency to maximize cooking chemicals recovery.

The CMPC Guaíba mill has already been the benchmark of the industry as an odorless mill. The collection and handling of the mill’s odorous gases is 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 onsite and remote expert support. The VII services include Valmet performance center support, data discovery, dynamic centerline advisor, performance monitoring tools, and operator training simulator.

 

2023 promises an interesting ride for print in India

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. While the print and packaging industries have been resilient in the past 33 months since the pandemic lockdown of 25 March 2020, the commercial printing and newspaper industries have yet to recover their pre-Covid trajectory.

The fragmented commercial printing industry faces substantial challenges as does the newspaper industry. While digital short-run printing and the signage industry seem to be recovering a bit faster, ultimately their growth will also be moderated by the progress of the overall economy. On the other hand book printing exports are doing well but they too face several supply-chain and logistics challenges.

The price of publication papers including newsprint has been high in the past year while availability is diminished by several mills shutting down their publication paper and newsprint machines in the past four years. Indian paper mills are also exporting many types of paper and have raised prices for Indian printers. To some extent, this has helped in the recovery of the digital printing industry with its on-demand short-run and low-wastage paradigm.

Ultimately digital print and other digital channels will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future. For instance, there is no alternative to a rise in textbook consumption but this segment will only reach normality in the next financial year beginning on 1 April 2023.

Thus while the new normal is a moving target and many commercial printers look to diversification, we believe that our target audiences may shift and change. Like them, we will also have to adapt with agility to keep up with their business and technical information needs.

Our 2023 media kit is ready, and it is the right time to take stock and reconnect with your potential markets and customers. Print is the glue for the growth of liberal education, new industry, and an emerging economy. We seek your participation in what promises to be an interesting ride.
