Tenova has been awarded a contract to supply an Acid Regeneration Plant (ARP) to Delna S.p.A., a subsidiary of the ArcelorMittal CLN Distribuzione Italia Group. The ARP will serve Delna’s pickling plant in Brivio, Italy, with a processing capacity of 2,000 liters per hour.
The installation of this advanced ARP reflects Delna’s continued investment in eco-friendly technologies. Utilizing Tenova Italimpianti’s expertise, a prominent supplier of technologies for heat treatment, reheating, and acid regeneration, the ARP will regenerate waste acid from Delna’s pickling line, contributing significantly to the facility's sustainability efforts by reducing its environmental footprint.
The plant will be equipped with Tenova’s BLUEdriven™ package, which includes advanced monitoring and control systems to enhance production flexibility and optimize operational costs, while ensuring minimal environmental impact. The BLUEdriven™ FlexCapacity process is a key feature, offering the ability to adjust production to meet varying market demands without interrupting ARP operations, thus ensuring energy efficiency and extending the plant’s operational lifespan.
Incorporating the ZeroWaste fully automated process, the new ARP will recycle rinsing and scrubber water from the pickling process, effectively recovering chlorides and closing the production loop. This approach not only improves plant efficiency but also allows for future upgrades through a modular systemic design without requiring extensive equipment modifications.
The environmental benefits of the project have been a focus from the outset. “The challenge of this specific project is the location of the plant itself, which is surrounded by a national park. Since the beginning, both the customer’s and Tenova’s goal has been the protection of the sensitive environment,” stated Gregor Kappacher, Project Director at Tenova Austria. “Thanks to our expertise and sustainable technology, we have designed a plant that fully complies with the latest environmental standards, while being cost-effective and flexible for future development.”
The ARP will also feature the BLUEdriven™ Emission Control system, which is designed to meet the strictest emission regulations. Its multiple-stage cleaning process ensures an effluent-free operation, resulting in zero environmental contamination. Additionally, the plant will integrate Tenova Edge, an IIoT gateway that connects the ARP to Tenova’s digital platform, providing Delna with tailored dashboards that monitor key performance indicators.
Tenova will offer ongoing technical and technological support for 24 months after the ARP's completion, both on-site and remotely, to optimize performance continuously.
“With this project, Delna, already a key player in the Italian and European steel industry, further enhances its commitment to environmental sustainability and eco-friendly processes,” commented Gabriele Fabbi, Plant Manager at Delna.
