Klabin starts up the world’s first commercial-grade, concentrated sulfuric acid plant in a pulp mill

Klabin has successfully started up a sulfuric acid plant supplied by ANDRITZ at its Ortigueira/PR plant in Brazil. The plant is a world first and has the capacity to produce 150 tons of commercial-grade sulfuric acid per day from concentrated odorous gases and elemental sulfur. It serves the pulp lines at Klabin’s Puma Unit and makes the site completely self-sufficient in sulfuric acid by recycling sulfur from the waste streams.
