Valmet will deliver a comprehensive package of critical valves and valve automation solutions to a lithium project run by Sibanye-Stillwater’s subsidiary Keliber Oy in Kokkola, Finland.

The order is included in Valmet’s orders received of the third quarter 2023. Valmet’s full scope delivery to the lithium project also includes the Valmet DNA automation system. The order was announced in April 2023.

The construction of the lithium refinery started in March 2023 and the production ramp-up is planned for the second half of 2025.

“The production of battery chemicals is a new and demanding industry. Our aim is to develop a sustainable operation to produce battery-grade lithium hydroxide. We therefore also expect our partners to deliver both the technologically most reliable, environmentally efficient solutions and know our production requirements well. Valmet has strong experience in delivering valve solutions to demanding chemical processes, as well as a comprehensive product portfolio that matches our production. It’s also important to us that original spare parts, as well as maintenance and expert services, are easily and timely available to us in all stages of production,” says Juha Kerttula, Electrical and Automation Manager of Keliber.

“The selection of optimal valves and actuators specifically for the requirements of each process can contribute to the operational reliability of production, a reduction in water consumption, energy efficiency, and minimized emissions or impurities. With seamless integration between valves and the Valmet DNA automation system, we will be able to identify potential issues in the process very broadly and thus improve reliability in the customer’s process throughout the lifecycle. We are honored by Keliber’s trust and look forward to our collaboration in this landmark operation,” says Marko Lindeman, Director, Finland and Baltics at Valmet’s Flow Control business line.
