Chemical Cleaning
Why Is Chemical Cleaning Important?
Industrial systems that handle water, steam, or process fluids build up scale, fouling, and corrosion deposits over time. Here is why removing them chemically matters:
- Even a 1 mm scale layer on boiler tubes can increase fuel consumption by up to 7 percent, and chemical cleaning dissolves deposits to bring surfaces back to bare metal.
- Deposits create hot spots, restrict flow, and cause under-deposit corrosion that leads to tube leaks and cracked components.
- Fouling-related failures are among the leading causes of forced outages in plants, and clean systems run longer between interventions.
- Chemicals dissolve deposits at the molecular level, cleaning complex geometries, tube interiors, and dead legs that brushes and scrapers miss.
- Pre-commissioning chemical cleaning removes mill scale, oil, and construction debris so new systems begin operating clean and corrosion-free.
- Removing corrosive deposits and finishing with passivation slows metal degradation and helps equipment reach its full design life.
- Cleaner heat transfer surfaces mean less fuel, less energy, and less chemical dosing to compensate for lost efficiency.
- Controlled deposit removal reduces the risk of pressure part failures and keeps equipment within inspection and regulatory requirements.
Equipment and Systems That Require Chemical Cleaning
Boilers and steam generators need water side removal of hardness scale, iron oxides, and silica to restore heat transfer and prevent tube overheating, while heat exchangers and condensers require dissolving of process side fouling and cooling water scale that reduce thermal efficiency.
Cooling towers and cooling water circuits are treated for scale, biofilm, and algae that restrict flow and promote corrosion, and pipelines and process piping undergo degreasing, pickling, and flushing to remove oil, mill scale, and rust from both new and in-service lines. Reactors and vessels are cleaned of polymer buildup, catalyst residue, and process deposits between production cycles, and storage tanks require sludge removal and surface preparation ahead of inspection or product changeover. Whether the goal is restoring efficiency in operating equipment or preparing new systems for startup, chemical cleaning reaches the deposits that mechanical tools leave behind.
Our Chemical Cleaning Services
Acid Cleaning, Pickling and Degreasing
We remove mill scale, rust, iron oxides, and hydrocarbon films using carefully selected chemicals for cleaning matched to your system metallurgy. Degreasing strips oils and process residues, while acid cleaning and pickling eliminate corrosion products and scale that throttle heat transfer and flow.
Passivation and Preservation
After cleaning, we passivate freshly exposed metal to rebuild its protective layer and prevent flash rusting. Preservation treatments keep cleaned surfaces protected during storage or standby, which is essential for new plant pre-commissioning.
Boiler, Heat Exchanger and Condenser Cleaning
Scale and deposits in boilers, exchangers, and condensers waste energy and shorten equipment life. Our industrial chemical cleaning restores thermal efficiency, reduces fuel and power consumption, and extends maintenance intervals.
Chemical Tank Cleaning and Decontamination
IME performs chemical tank cleaning for storage tanks, process vessels, and effluent systems, removing sludge, hydrocarbons, and hazardous residues. Our decontamination services make tanks and equipment safe for entry, inspection, hot work, or recommissioning, with full compliance to confined-space and environmental standards.
CIP, Foam, Vapor-Phase and Circulation Cleaning
We deploy the cleaning method that fits the asset and closed loop circulation (CIP) for piping and exchangers, foam cleaning for large-volume or hard-to-circulate systems (cutting solvent use and disposal volumes), and vapor-phase cleaning for complex geometries. Choosing the right method is what makes our chemical cleaning safe, fast, and thorough.
