- International technology group ANDRITZ has successfully started up a new
pulp mill for the Brazilian pulp producer Suzano in the municipality of
Ribas do Rio Pardo, Mato Grosso do Sul state. When fully operational, it
will be the world’s largest single-line eucalyptus pulp mill with an annual
production capacity of 2.55 million tons. It will also be one of the few
pulp mills in the world to run without fossil fuels, based on a raw material
of 100% planted trees. It will be energy self-sufficient, producing surplus
green power for its local suppliers and the national grid. “This new pulp
mill will increase our production capacity while significantly reducing our
environmental impact, supporting our financial and environmental goals. The
cutting-edge technologies applied are in line with our commitment to
sustainability and innovation. Trust and reliability are essential in a
project like this, and we found both in our partnership with
ANDRITZ,” says Maurício Miranda, Director of Engineering at Suzano and
responsible for the construction of the mill. ANDRITZ supplied a highly
resource-efficient pulp mill with leading technologies for fiber production
and chemical recovery on an EPCC basis (Engineering, Procurement,
Construction, Civil Works). The scope of supply included a complete wood
processing plant with five chipping lines, the world’s largest single-line
fiberline (capacity over 8,000 adt/d) with unique washing and bleaching
technology based on DD-Washers, an innovative pulp drying system with two
energy-efficient pulp drying lines, an energy-efficient black liquor
evaporation plant, a HERB recovery boiler to maximize steam production for
power generation, a biomass power boiler based on the high-performance
ANDRITZ EcoFluid Bubbling Fluidized Bed (BFB) technology, and a complete
white liquor plant with recausticizing plant and two lime kilns. To enhance
the mill’s environmental performance, ANDRITZ is also supplying gasification
plants to enable fossil-free operation of the lime kilns and a SulfoLoop
sulfuric acid plant to produce commercial grade sulfuric acid from the
mill’s concentrated odorous gases and elemental sulfur. This will recycle
sulfur from the waste streams and make the mill completely self-sufficient
in sulfuric acid. “We are honored that Suzano has chosen us as their EPCC
partner for the implementation of this flagship project, using our most
advanced technologies for efficiency and circularity,” says ANDRITZ
Executive Boa August 8, 2024 - International technology group ANDRITZ has successfully started a new pulp mill for Brazilian pulp producer Suzano in Ribas do Rio Pardo, Mato Grosso do Sul. When fully operational, it will be the world’s largest single-line eucalyptus pulp mill with an annual production capacity of 2.55 million tons. Notably, the mill will operate without fossil fuels, being energy self-sufficient and producing surplus green power for local suppliers and the national grid. ANDRITZ supplied the mill under an Engineering, Procurement, Construction, and Civil Works (EPCC) basis. The supply included advanced technologies for fiber production, chemical recovery, pulp drying, and power generation. The mill's design aims to enhance environmental performance with features like gasification plants for fossil-free lime kiln operation and a SulfoLoop sulfuric acid plant to recycle sulfur from waste streams. “This new pulp mill will increase our production capacity while significantly reducing our environmental impact, supporting our financial and environmental goals,” said Maurício Miranda, Director of Engineering at Suzano. ANDRITZ Executive Board Member Jarno Nymark expressed pride in Suzano's choice of ANDRITZ as their EPCC partner, emphasizing the use of advanced technologies for efficiency and circularity in this flagship project. January 18, 2023 - ANDRITZ has received an order from Brazilian pulp producer Suzano to deliver a SulfoLoop concentrated sulfuric acid plant for its new pulp mill that Suzano is building in the municipality of Ribas do Rio Pardo, state of Mato Grosso do Sul. The pulp mill, delivered by ANDRITZ, is in the construction phase with start-up scheduled for the second half of 2024.The sulfuric acid plant will have the capacity to produce 153 tons of commercial grade (>97%) sulfuric acid per day from the pulp mill’s concentrated odorous gases and elemental sulfur - thus making the mill completely self-sufficient in sulfuric acid and recycling sulfur from the waste streams. The ANDRITZ SulfoLoop solution is based on the Wet-gas Sulfuric Acid (WSA) technology for converting wet, sulfur-rich gases and elemental sulfur into sulfuric acid.The sulfuric acid mill will help the new Suzano mill in Ribas do Rio Pardo to control the sodium and sulfur (Na/S) balance and the sulfidity of the pulp mill. Also, the resource-efficiency of the mill will be improved because less sulfate needs to be discharged due to the optimized Na/S balance. An added advantage is that there is no need for hazardous sulfuric acid transport to the mill, which results in a major reduction in the truck transportation volume. The sulfuric acid plant also meets very strict air emission limits and therefore brings a significant improvement to the overall footprint of the new Suzano plant in Ribas do Rio Pardo.This order once again confirms the excellent business relationship between ANDRITZ and Suzano. Currently ANDRITZ is in the process of supplying all pulp mill technology and process equipment for the new Suzano plant in Ribas do Rio Pardo. Once completed, the pulp mill will be the world’s largest plant with a single eucalyptus pulp production line.SulfoLoop sulfuric acid plants are part of the company’s CircleToZero initiative, which includes new technologies aimed at optimizing pulp mill side streams. This global initiative for pulp and paper customers brings together the continuous development and improvement of existing ANDRITZ technology solutions with an ambitious innovation goal for the future: To eliminate unused side streams, create new added-value products, and lay the foundation for zero emissions and zero waste production. |
