Successful Bracell ‘Project Star’ startup for ANDRITZ
Austria-headed international technology group Andritz AG (ANDRITZ) has successfully started up key production equipment for the first of two state-of-the-art hardwood pulp production lines supplied for Bracell’s ‘Project Star’ in Lençóis Paulista, São Paulo, Brazil. The second line is expected to be started up by the end of September 2021.
In April 2019, Bracell Group, which is part of Singapore-based RGEP, officially launched ‘Project Star’, to increase annual production capacity at its Lençóis Paulista pulp mill.
According to ANDRITZ, the mill features two flexible, “environmentally-friendly” hardwood fiberlines for an annual capacity of 2.6 to 2.8 million tonnes of bleached kraft pulp or 1.5 million tonnes of dissolving pulp made from sustainably cultivated eucalyptus.
The ANDRITZ A-ConFlex continuous kraft and dissolving pulping technology enables flexibility in the production of high-quality dissolving pulp and kraft pulp.
With a capacity of 13 000 tonnes per day, the ANDRITZ HERB recovery boiler is the largest in the world. It will make the mill self-sufficient in energy supply and still supply around 180 MW of renewable electricity to the Brazilian power grid.
The scope of supply includes:
- a complete, high-capacity wood processing plant, enhanced with state-of-the-art ANDRITZ IIoT Smart Woodyard solutions to ensure optimum chip quality;
- two flexible fiberlines with DD-Washer technology;
- the world’s largest EvoDry Pulp Drying System, with two energy-efficient pulp drying lines and equipped with the Metris DryQ smart pulp drying solution and Metris remote connection to ensure a fast start-up;
- an ANDRITZ HERB recovery boiler;
- a non-condensable gas (NCG) treatment system.
With this delivery, ANDRITZ says that it “again confirms its position as the only technology supplier with solid references and experience in the continuous cooking of dissolving pulp.”
