Poing near Munich, June 18, 2026 – With the challenging refurbishment of the flue gas desulfurization plant at the Fenne power plant in Völklingen, Germany, REMA TIP TOP demonstrates the effectiveness of its solutions in industrial corrosion protection. The project was carried out by TIP TOP Oberflächenschutz Elbe and serves as a prime example of how a technically reliable and economically viable solution can be implemented even under challenging conditions. Thanks to this measure, safe operation of the power plant is ensured until the planned end of coal-fired power generation.
Applications in the field of flue gas desulfurization—a key process for reducing sulfur dioxide in exhaust gases—place high demands on the material. In this environment, components are constantly exposed to high levels of stress caused by moisture, chemical influences, and corrosive media. Steel structures in particular, such as scrubbers and ducts, therefore require effective protection against corrosion, wear, and chemical stress.
At the Fenne power plant, the washers were completely re-lined with rubber by REMA TIP TOP. The proven CHEMOLINE 4B system was used, with a coating thickness of 4 millimeters applied over an area of approximately 2,400 square meters. In areas subject to particularly high stress, a two-layer application with a total thickness of 8 millimeters was implemented. In addition, the raw gas duct was completely lined over an area of approximately 535 square meters using the COROFLAKE 23 coating system.
“The requirements for flue gas desulfurization systems are clearly defined, yet technically demanding. A key factor is a protective coating that remains permanently impermeable and durable, functioning reliably even under varying operating conditions,” says Markus Potyka, Senior Construction Manager and Coating Inspector at TIP TOP Oberflächenschutz Elbe. “Our materials are characterized in particular by their high diffusion resistance, thereby offering effective protection against the penetration of corrosive media.”
The main challenge of this project concerned the general conditions. REMA TIP TOP was
called in at short notice to join an already ongoing project and took on the planning and
implementation within a significantly shortened time frame. The project was carried out on-site
on a 24/7 basis and was organized by the construction management, project management,
application engineering, and quality assurance teams. “Taking on and executing the project at
short notice under significant time pressure demonstrates our operational strength in project
execution,” explains Michael Meyer, Project Manager at TIP TOP Oberflächenschutz Elbe.
“The close collaboration among all departments involved – from technical design to on-site
implementation – was crucial.”
auf der Baustelle.“
The Fenne Power Plant is a long-standing industrial site in the Saarland region of Germany. It consists of several plant complexes. In the future, the power plant will operate on a limited schedule. This places additional demands on the durability of the protective systems because the constant start-up and shutdown cycles cause significant corrosion-related wear. For the operator, this approach offers clear economic benefits. At the same time, the plant underwent technical refurbishment to ensure safe operation in the coming years. Although rubber lining in power plants is declining due to the phase-out of coal, Asia and Africa are growth markets where REMA TIP TOP’s expertise is in demand.
The project also highlights REMA TIP TOP’s strategic focus on “Surface Protection.” In addition to the quality of the materials, emphasis is placed on rapid responsiveness, detailed project preparation, and structured implementation, even under demanding conditions. "Our market differentiation does not stem solely from the product itself, but also from the combination of material expertise, engineering, and speed of implementation," says Michael Meyer. "This integration is especially crucial to the success of complex maintenance projects."
