Repair and Rebuild of Acid Neutralization Trench Lines in Power Plant

Industry: Power

Area of Application: Acid Neutralization Trench

Products Used: Duromar DF 1301 + DuroFil + Duromar DF-4301

Protection Against: Acidic Water Mixed with Solvents

Problem:

Acid resistant tiles that were installed along the neutralization trench lines of a Thermal Power Plant had completely worn out within a span of 12 months. This as a result had caused severe corrosion across the civil & concrete areas of the DM plant, forcing the plant maintenance teams to replace and repair the acid-resistant tiles frequently. The drastic increase in downtime & maintenance costs required the plant to adopt a more bulletproof protective flooring system that would help overcome the damages incurred and ensure the smooth operation of the DM Plant.

Damaged acid Neutralization Trench lines

Solution:

On inspecting the damages andassessing the problems, Arudrareckoned to redo the entire civil worksusing a 100% solid, 3-part epoxy grout(Duromar DuroFil) along with a top layerof the acid-resistant epoxy liner(Duromar DF – 4301). The existing tiles were removedthroughout the trench and the severelydamaged portions were rebuilt withReinforced Cement Concrete (RCC).

The concrete surface was then thoroughly prepared to ensure a clean and rough finish was achieved and Duromar DF – 1301 concrete sealant was applied to ensure all the concrete pinholes/seepages were sealed. Duromar DuroFil, a specially formulated100% solid epoxy grout used in rebuildings everely chemically attacked concrete floors and secondary containment areas were then built up to a thickness of 6mm – 7mm throughout the trench lines.

Surface Preparation Of Trench

Durofil Epoxy Grout & Rebuilt

Result:

Installation of DuroFil followed by Duromar DF – 4301 successfully helped provide a solid foundation and outstanding acid/chemical resistance for the neutralization trench, covering a surface area of approximately 50 m².

This expert Duromar 100% Solid (Zero VOC) Epoxy grout & rebuild solution not only helpedsolve a range of operational & maintenance issues but also greatly helped inenhancing the Asset Life of these concrete areas exposed to aggressive chemical environments.

Arudra successfully executed this challenging installation within a span of 7 days,providing the end-user with risk-free operations for years to come.
