(PRESS RELEASE) GRAZ, 18-Jan-2023 — /EuropaWire/ — ANDRITZ, an international technology group based in Austria active in the supplies of plants, has received an order from Brazilian pulp producer Suzano to deliver a SulfoLoop concentrated sulfuric acid plant for its new pulp mill in Ribas do Rio Pardo, Brazil. The plant, which is part of ANDRITZ’s CircleToZero product portfolio, 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. This will make the mill completely self-sufficient in sulfuric acid and recycling sulfur from the waste streams.

The SulfoLoop solution is based on the Wet-gas Sulfuric Acid (WSA) technology, which converts 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 control the sodium and sulfur (Na/S) balance and the sulfidity of the pulp mill, and improve resource-efficiency by reducing the amount of sulfate discharged. Additionally, the sulfuric acid plant will reduce the need for hazardous sulfuric acid transport to the mill, resulting in a significant reduction in 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 confirms the excellent business relationship between ANDRITZ and Suzano, with ANDRITZ currently in the process of supplying all pulp mill technology and process equipment for the new Suzano plant. Once completed, the pulp mill will be the world’s largest plant with a single eucalyptus pulp production line.
