On October 10, 2024, Tenova, renowned for its sustainable technologies, announced its partnership with Delna, part of the ArcelorMittal CLN Distribuzione Italia Group. The contract entails the installation of an Acid Regeneration Plant at Delna’s facility in Brivio, Italy, with an impressive capacity of 2,000 liters per hour. This project represents a significant step toward enhancing the environmental performance of Delna’s operations, particularly in the area of acid waste management.
Delna, a key player in the pickling service of coils and wire rods, recognizes the need for sustainable practices in the steel industry. By collaborating with Tenova, the company aims to recover waste acid utilized in its pickling line, thereby minimizing its environmental footprint. The ARP is expected to streamline the regeneration of acid, ensuring that the production process adheres to modern sustainability standards while improving operational efficiency.
The ARP will be equipped with Tenova’s innovative BLUEdriven™ technology, which includes advanced package solutions designed for optimal performance. This cutting-edge system will be governed by a tailored monitoring process, enhancing production flexibility and optimizing operational costs. By utilizing the BLUEdriven™ FlexCapacity process, Delna can adjust its steel production in response to market demands while maintaining continuous and stable ARP operation. This adaptability not only optimizes energy consumption but also contributes to the plant's overall ecological footprint.
An integral feature of the ARP is the ZeroWaste fully automated process, which effectively recycles rinsing and scrubber water from the pickling operation. This approach recovers chlorides within the production cycle, facilitating a closed-loop system that significantly boosts plant efficiency. Furthermore, the modular design of the ARP enables future enhancements without the need for substantial equipment modifications, allowing for continued growth and adaptability.
The BLUEdriven™ Emission Control system sets a new benchmark for Best Available Technology in the industry. This sophisticated system ensures compliance with stringent emission regulations by incorporating a multiple-stage cleaning process that produces effluent-free results, thereby preventing any environmental contamination. Such proactive measures highlight Tenova's commitment to advancing sustainability in industrial processes.
To facilitate real-time monitoring and performance optimization, the ARP will be integrated with Tenova Edge, the company's Industrial Internet of Things gateway. This connectivity will enable Delna to access customized dashboards displaying key performance indicators related to ARP operations. After the plant's commissioning, Tenova will extend technical and technological support for 24 months, both remotely and on-site, ensuring ongoing optimization of the plant's performance.
The collaboration between Tenova and Delna underscores a shared commitment to environmental sustainability and eco-friendly practices within the steel industry. Gabriele Fabbi, Plant Manager at Delna, noted that this project enhances the company's dedication to sustainable operations, while Gregor Kappacher, Project Director at Tenova Austria, highlighted the importance of protecting the sensitive environment surrounding the plant, located near a national park. Through their innovative technologies, Tenova and Delna aim to set a precedent for sustainable practices in steelmaking, ensuring that economic growth and environmental responsibility go hand in hand.
