Valmet will deliver a new recovery boiler, an ash crystallization plant, and an odorous gas handling system to Klabin’s Monte Alegre pulp and paper mill as part of Klabin’s announced modernization project. The delivery includes automation and flow control solutions consisting of extensive optimization systems and control valves. The new equipment is estimated to be taken into operation by the end of 2026. The order is included in Valmet's orders received of the third quarter 2024. The value of the order will not be disclosed. The value of an order of this size with extended scope is typically above EUR 100 million. The delivery is part of Klabin’s investment of BRL 1.7 billion (about EUR 285 million) that seeks the operational continuity of the Monte Alegre mill. “Klabin Monte Alegre mill modernization project aims to increase the efficiency, competitiveness, and sustainability of the mill, the largest paperboard producer in Brazil. We strategically chose Valmet because of its technology, suitable interface with the recovery plants, and a good plan for implementation and assembly,” says Edemilson Schroeder Pagano, General Project and Engineering Manager, Klabin. “The new recovery boiler and ash crystallization system represent high-technology solutions that will give performance and optimized OPEX for Klabin’s Monte Alegre mill. This new project reinforces the long-lasting partnership between Klabin and Valmet in developing sustainable solutions together. All of us at Valmet are proud to be part of this significant modernization project,” says Fernando Scucuglia, Pulp & Energy Director, South America, Valmet. “The new recovery boiler and ash crystallization with connected optimizers will improve the mill's safety and operational reliability. The collection, handling, and incineration of non-condensable gases will also help reduce the environmental impacts,” says Jussi Mäntyniemi, Vice President, Recovery, Pulp and Energy, Valmet. Technical details of the delivery The Valmet Recovery Boiler includes several high-power features to maximize energy efficiency. Leading safety solutions and advanced process controls for optimized performance and high-performance predictability support the operation. The boiler will have a capacity of 1,950 tonnes of dry solids per day (tDS/d). The Valmet Ash Crystallization Plant for ash treatment will have the capacity to process 140 tonnes of ash per day. The ash treatment is an integral part of the mill’s chemical recovery cycle, removing chloride and potassium from the liquor cycle, thus reducing corrosion and ash accumulation in the boiler. The high-efficiency system guarantees continued operation of the recovery boiler for long periods and low maintenance and operating costs. The delivery also includes Valmet NCG solutions, covering the collection and handling of the mill’s odorous gases. The new equipment will be enhanced with an automation scope that will optimize the performance with a comprehensive combination of advanced monitoring and prediction applications, such as a boiler diagnostic camera system, an ash analyzer, and Valmet Industrial Internet applications, including a complete package of advanced process controls, a Recovery Boiler Optimizer and Valmet Training Simulators. They will provide continuous operation, autonomous controls, and high-performance predictability. In addition, 140 Neles and Jamesbury valves will be delivered, including globe valves equipped with ND9000 smart positioners and Axiom on/off valve controllers as part of Valmet's offering, guaranteeing safety and reliability to the new recovery boiler.
