Project Success: Chemical Cleaning of HRSG (Process Side)
We are proud to share the successful completion of our latest Chemical Cleaning activity for a Heat Recovery Steam Generator (HRSG) process side.
Our Objective:
Remove deposits, scaling, and corrosion products
Eliminate oil, grease, and construction debris
Improve heat transfer efficiency and operational reliability
Our Approach:
β
Pre-Cleaning Inspection β Thorough assessment of tubes, headers, and internals
β
Circulation Setup β Isolation, temporary piping, leak testing & DM water flushing
β
Chemical Cleaning Process:
Degreasing / Alkaline Cleaning (NaOH + Surfactant)
Acid Cleaning / Descaling (Inhibited HCl / Citric Acid)
Neutralization & Passivation (Sodium Nitrite + Ammonia)
β
Post-Cleaning Inspection β Borescope inspection, sample analysis & cleanliness verification
Safety First:
π‘οΈ Full PPE | Area barricading | Continuous HSE monitoring | Emergency neutralization on standby
Results Achieved:
βοΈ Heavy deposits & scale successfully removed
βοΈ Improved water circulation & reduced pressure drop
βοΈ Heat transfer efficiency increased
βοΈ System restored to safe & reliable operating condition
π‘ Conclusion: The HRSG has been restored to safe, efficient, and reliable operating condition, ensuring long-term performance and plant reliability.
