Valmet to supply ash treatment system to LD Celulose in Brazil

Espoo, Finland - Valmet will supply an ash crystallizer plant with a capacity of 300 tons of ash per day to LD Celulose S.A. in Brazil. The ash crystallizer delivery is part of Lenzing’s and Duratex’s joint venture LD Celulose’s project to build a new 500,000 ton/year dissolving pulp mill in Minas Gerais state, Brazil.

In January, Valmet announced an extensive technology and automation delivery for the project. The new mill is scheduled to start up in 2022. The order was included in Valmet’s orders received of the first quarter 2020. The value of the order is not disclosed. The value of a delivery of this size and scope is typically around EUR 10-15 million.

“Our new pulp mill will have a positive socio-economic impact throughout the region. When choosing partners for this project we have emphasized reliability, energy efficiency and best environmental practices. We chose Valmet to deliver their ash crystallization solution because the Valmet-concept will fulfill our request in the best way,” said Roland Feiner, chemical recovery implementation manager, LD Celulose.

“Our ash crystallization technology is well suited for large pulp mills and represents proven technology that provides the mill with better environmental performance and increased production efficiency,” said Fernando Scucuglia, director, pulp and energy, South America, Valmet.

The Valmet ash crystallizer will have capacity of 300 tons of ash per day and will recover mill chemicals and remove non-process elements, primarily chloride and potassium, from the mill’s liquor cycle.

“This will be the third ash crystallization system delivery from Valmet. Our largest installation with a capacity of 920 tons ash per day is in Indonesia and another 480 tons per day ash crystallizer in China. This third installation will be a standalone plant, which means that it will have a high degree of independence from other mill processes,” said Fredrik Kall, director for evaporation, ash and bio- technologies, pulp and energy business line, Valmet.

LD Celulose’s upcoming 500,000 ton/year dissolving pulp mill is located in the cities of Indianópolis and Araguari in Minas Gerais state in Brazil. With this new addition of ash treatment system, Valmet’s total delivery includes now a fibre line, a pulp drying and baling line, an evaporation plant, a white liquor plant, an ash crystallization plant and a mill-wide automation system.
