Andritz has received an order from the Brazilian pulp and paper company Suzano to deliver an energy-efficient Ash ReCrystallization (ARC) plant for the recovery boilers at its eucalyptus kraft pulp mill in Barra do Riacho, Brazil. The estimated start-up date for the ARC plant is the first half of 2022.

The Andritz ARC plant removes the harmful chloride and potassium from the ElectroStatic Precipitator (ESP) ash and returns valuable chemicals to the chemical recovery cycle. The plant to be supplied is designed to handle 550 tons of ESP ash daily.

Featuring the new energy recovery technology, the ARC plant will optimize energy efficiency significantly. This technology is also based on an enhanced evaporative crystallization concept that will improve the recovery process.

Suzano is the largest pulp and paper company in Latin America and a leader in the paperboard market.
