4. The final application with Belzona 1391
60 metre tall process CO2 absorber tower required corrosion protection
The applications were carried out in accordance with Belzona Know-How Leaflet TCC-3. The customer pad welded deeply pitted areas. Less damaged areas were filled and smoothed with Belzona 1311 before coating with Belzona 1391.
The process tower had worked previously without internal linning until the discovery of major erosion / corrosion defects. The first application of Belzona was carried out in 2014 and the condition was inspected every year. The last inspection in 2016 has reported no degradation of Belzona linning.
