Engineered Chemical Cleaning
PetroDecon specializes in engineered chemical cleaning solutions for critical process equipment across multiple end markets; refining, petrochemical, utilities, pulp and paper industries. Whether pre-commissioning, start-up, maintenance, project ,environmental compliance, problem related issues or, our approach is built around precision, safety, and field-proven results. We clean and restore equipment such as exchangers, towers, piping systems, knockout drums, vessels, and tanks using tailored chemical formulations applied through a variety of methodologies and proven techniques. We customize every cleaning solution to incorporate a number of critical criteria; application safety, system metallurgy, fouling or deposit composition and characteristics, operational restrictions, waste volumes, waste profiles, disposal options, and overall economics.
Our pre-commissioning services focus on removing mill scale, oils, rust, and other contaminants to ensure new systems are startup-ready. We provide passivation treatments to protect cleaned surfaces from corrosion. For operational and maintenance cleanings, we incorporate specialty solvents and application techniques to remove asphaltenes, coke, polymers, and scale.
Our goal is restoring production and operational efficiency while reducing downtime and the need for mechanical intervention. Our application portfolio , including full-fill recirculation, cascade and sparge, vapor phase, foam cleaning, and method combinations depending on the equipment configurations and cleaning requirements.
Online Cleaning
PetroDecon’s online chemical cleaning solutions are engineered to restore equipment and process system performance without a unit shutdown. This approach allows operators to address fouling, flow restrictions, and efficiency loss while maintaining normal production, making it ideal for systems with parallel flow capability or components to be safely isolated during treatment.

This approach allows operators to address fouling, flow restrictions, and efficiency loss while maintaining normal production, making it ideal for systems with parallel flow capability or components to be safely isolated during treatment.
This approach typically requires no major mechanical modifications and can be completed in under 24 hours. Online cleaning reduces overall turnaround scope, avoids production loss, and restores 90–95% of performance, all while minimizing resource consumption and field disruption. It’s a proven, data-driven solution to improve asset performance in live operations.
Reactor & Catalyst Bed Cleaning
Conventional reactor clearing techniques often leave residual hydrocarbons due to channeling or vapor lock. PetroDecon addresses this with an engineered solution that involves injecting proprietary solvents such as CC-925 during the reactor cool-down or recycle phase. This method breaks down hydrocarbon binders, enhances penetration into catalyst beds, and improves catalyst flow during removal.
Our process significantly reduces risk, accelerates cool-down, and ensures a safer and more efficient operation. This approach is especially valuable when handling pyrophoric materials or during catalyst changeouts where safety and speed are critical.
Turnaround Optimization
PetroDecon provides complete turnaround support services, from early planning through execution and testing. We develop custom scopes of work that integrate with client shutdown timelines and decommissioning plans. Our services include degassing and decontamination, neutralization and passivation, acid cleaning, and vapor-phase or foam-based applications.
Our pre-job engineering process includes reviewing PFDs and P&IDs, calculating chemical volumes, developing injection schemes, preparing sampling strategies, and estimating equipment and utility needs. We also align with client operations teams to finalize work method statements, job safety analyses, and waste management plans. PetroDecon provides single-point accountability throughout the project and offers flareless clearing methods using custom-built scrubbers and vapor systems to reduce emissions.
Degassing & Decontamination
PetroDecon’s degassing and decontamination services rapidly remove hazardous compounds such as benzene, hydrogen sulfide, VOCs, ammonia, and pyrophoric iron. Using proprietary vapor-phase and liquid chemistries, we prepare systems for safe entry often within hours.
Our degassing process typically achieves benzene concentrations below 0.05 ppm, with no need for fresh air equipment entry. Chemistries are designed to lift hydrocarbons from surfaces and separate cleanly from water, reducing emulsification and waste generation. This makes us a preferred partner for safe, fast system turnover and reduced downtime.
Techniques and Methodologies
At PetroDecon, we offer a full suite of chemical cleaning methodologies designed to match the specific requirements of your unit, system, and turnaround goals. Our solutions are tailored to ensure the best method for your specific needs, whether it’s a traditional acid cleaning or a custom-engineered chemical circulation.
PetroDecon is fully equipped and experienced in executing a wide range of industry-standard cleaning techniques, including:
- Inhibited Acid Cleaning (e.g., HCl, sulfamic, citric) for scale and corrosion removal
- Solvent-Based Degreasing to break down hydrocarbons, protective coatings,and greases
- Passivation Treatments using oxidizers, acids, alkaline, and proprietary formulations
- Alkaline Cleaning and Boilouts for polymeric and organic residue removal
- Water Flushing and Final Rinses to eliminate residue and prepare systems for startup
Application methods include full fill and circulation, cascade and sparge techniques, injection with carrier fluids, vapor-phase degassing, foam cleaning, and high-temp chemical circulation all selected based on system geometry, fouling type, safety, and project goals.
Specialized Equipment
Our cleaning programs are supported by a fleet of dedicated tools and mobile units, including:
- Injection skids and skid-mounted pumps
- Drain header systems with condensing and vapor recovery capabilities
- Portable vapor-phase injection skids
- Frac tanks and mobile containment units
- Portable heat exchangers
- Field laboratories and GC testing units
- Portable scrubbers and activated carbon beds
This equipment ensures safe, flexible, and site-optimized execution in any facility.
Decon Sampling & Real-Time Testing
At PetroDecon, we rely on analytical validation, not guesswork. Our onsite mobile labs allow us to provide real-time data for benzene, H₂S, total hydrocarbons, and LEL readings that support operational readiness and entry clearance. Samples are collected in a controlled, safe manner and analyzed using certified gas chromatography. These results are logged and shared instantly with client teams, helping reduce rework and ensure compliance.
Fin Fan Foaming
At PetroDecon, we specialize in fin fan foaming, a cutting-edge cleaning technique designed to maintain the efficiency and longevity of your heat exchangers. This process involves applying a high-volume, low-pressure foam to the fins of heat exchangers, effectively removing accumulated dirt, debris, and contaminants without causing any damage. Regular fin fan foaming is crucial for ensuring optimal heat transfer, reducing energy consumption, and extending the lifespan of your equipment. Our environmentally friendly, biodegradable cleaning solutions are safe for both your equipment and the environment. Additionally, our method allows for cleaning while the equipment is operational, minimizing downtime and maximizing productivity. Trust PetroDecon to keep your exchangers running at peak performance with our reliable and efficient fin fan foaming services.
