Meeting the demands of a changing energy landscape
The energy sector is undergoing a fundamental transformation with power plants required to operate flexibly with frequent start-ups, shutdowns and preservation periods. These demanding conditions have made traditional water-steam cycle treatments insufficient.
Kurita’s Cetamine® Technology, based on Film Forming Amines, addresses this challenge by providing advanced corrosion protection specifically for cycling and intermittent plant operation.
This innovative treatment integrates with existing chemical programs. As a result, operators benefit from improved system protection, reduced turbine coupling times and improved water and energy efficiency.

Enhancing Steam Cycle Reliability with Cetamine® in Intermittently Operating Power Plants
Cetamine® is Kurita’s patented corrosion inhibitor designed for intermittently operating power plants. It forms a protective film in the water-steam cycle, mitigating flow-accelerated corrosion (FAC) and safeguarding systems with ferrous and mixed metallurgy components.
Plant operators benefit from reduced iron oxide transport during cycling and stop-start operations, enabling faster start-ups and shorter turbine coupling times.
Widely used in plants that experience frequent shutdowns and start-ups, Cetamine® is an ideal solution for both wet and dry lay-up preservation. After implementation, plants retain full operational flexibility without compromising steam quality.
Cetamine® consistently delivers significantly lower total iron levels during start-up compared to conventional treatments such as AVT(O) or AVT(R). This improvement often enables reduced blow-down rates, leading to measurable savings in water and energy consumption. In turn, this lowers the environmental footprint and supports power producers in achieving their sustainability goals.
