At the same time, this pioneering project has raised the degree of plant automation and increased the operating reliability.

Even when the COVID-19 pandemic was at its most serious in Portugal, Papeleira Coreboard – utilizing remote assistance from ANDRITZ – still managed to start up its new, state-of-the-art LC pulping system.

Increasing capacity of the lime kiln is time consuming and costly as it usually involves the lengthening of the existing kiln shell, or even a replacement with a larger diameter. ANDRITZ experts have approached the challenge from a completely different angle, and now a capacity increase of up to 40% can be achieved at much lower costs.

Brazilian pulp and paper giant Klabin is further closing the circular sustainability loop at its Puma I and Puma II projects in the south of the country. Soon it will be making its own sulfuric acid from captured non-condensable gases at its Ortigueira mill site. ANDRITZ expertise is paving the way.

ANDRITZ played a major part in Stora Enso’s Oulu mill success in reaching a new era as the mill was converted from fine paper to kraftliner production. The virgin fiberbased kraftliner produced by the mill will serve the strongly growing global packaging market.

Mondi Swiecie’s integrated mill in Poland needed to increase its pulp capacity by 25% to meet growing demand from its five five paper machines using virgin fiber. The solution was a complex but hugely successful combination of utilizing older equipment at the same time as installing new, state-of-the-art technology from ANDRITZ.

ANDRITZ has created a simple but remarkably effective way to improve energy efficiency of the pulp mill, at the same time increasing the mill overall evaporation capacity. The DEvap is a small digester evaporator unit integrated into the cooking plant.

Suzano’s pulp mill in São Paulo has generated significant savings in the plant’s evaporation process by using the Metris UX technology from ANDRITZ for the digital transformation of its processes.

ANDRITZ is once again providing opportunities for pulp producers to increase the range of added value bio-products in their product portfolios with its A-ConCrystal™ continuous technology for microcrystalline cellulose (MCC) production. There is still an increasing demand for the use of MCC in several fields of applications, strengthening the position of being one of the fastest growing areas in the use of specialty celluloses.

Suzano Imperatriz, located in Maranhão, northern Brazil, is one of the new breed of giant pulp mills. The mill has recently undergone a number of improvements including the implementation of a smart bleaching system from ANDRITZ that is making a real difference when it comes to chemical consumption.

Running a pulp mill successfully requires that all processes, technology, and equipment work in harmony across the entire system with the whole chain being only as strong as its weakest link. Metris DryQ™ is the new intelligent solution from ANDRITZ, designed for monitoring data from drying systems, helping to strengthen a vital link in the production chain to optimize the drying performance.

Arauco’s MAPA project in Horcones, Chile is now in full swing; the earthmoving and foundation building has almost been completed and the civil works have started. ANDRITZ is a major supplier to the project and has been closely working together with Arauco, which will see the Chilean company become the third largest producer of eucalyptus pulp in the world. Start-up is scheduled for the first quarter of 2021.

Stora Enso’s Imatra Mill, located in eastern Finland, is one of the world’s largest producers of liquid packaging board.
