Tenova to supply an Acid Regeneration Plant for Delna in Italy

Castellanza – Tenova, a leading developer and provider of sustainable solutions for the green transition of the metals industry, has been awarded a contract by Delna S.p.A., an ArcelorMittal CLN Distribuzione Italia Group company and primary provider of pickling service of coils and wire rod, for its plant in Brivio, Italy, for an Acid Regeneration Plant (ARP) with a capacity of 2.000 l/h.

Thanks to this partnership and the innovative technologies of Tenova Italimpianti, the leading technologies and equipment supplier for reheating, heat treatment, strip processing, and acid regeneration plants, Delna’s investment will boost the green transition of its plant, recovering the waste acid used in its pickling line and therefore minimizing its environmental footprint.

The new ARP will be equipped with the BLUEdriven™ cutting-edge package solutions that will be controlled by a customized monitoring process, increasing production flexibility and optimizing operative costs, while guaranteeing minimal environmental impact.

The BLUEdriven™ FlexCapacity process provides unique and significant capacity flexibility that allows adjustments to steel production according to demand, while the ARP’s operation remains uninterrupted and stable. This configuration optimizes energy consumption, reduces the plant’s ecological footprint, and extends its lifetime.

The ZeroWaste fully automated process recycles the rinsing and scrubber water from the pickling process at different concentrations, recovering the available chlorides of the production cycle and closing the loop. It will also enable plant efficiency at a superior level. Additionally, the modular systemic design will allow for further improvements to the plant without major modifications to its equipment.

The BLUEdriven™ Emission Control system will set a new level of Best Available Technology (BAT). It allows to comply with the strictest emission values: its effluent-free, multiple-stage cleaning section will result in no environmental contamination.

The ARP will be equipped with Tenova Edge, the Tenova IIoT gateway which allows the connection of the ARP to Tenova’s IIoT Platform. Tenova will provide Delna with tailored dashboards, showing KPIs related to the ARP operation.

After completion, Tenova will provide technical and technological support for 24 months, both remotely and on-site, with the aim of continuously optimizing performance.

“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.

“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.”
