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. The new mill is scheduled to start up in 2022.
The value of the order is not disclosed. The value of a delivery of this size and scope is typically around Euro 10-15 million.
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,” tells 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 fiber line, a pulp drying and baling line, an evaporation plant, a white liquor plant, an ash crystallization plant and a mill-wide automation system.
LD Celulose is a joint venture where Lenzing holds a 51% and Duratex a 49% stake.
Valmet is the leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries.
