Chemical Cleaning
Targeted solutions for complex contamination
Chemical cleaning is essential for maintaining clean, corrosion‑free and high‑performing systems, removing deposits and contaminants that mechanical cleaning alone cannot address.
InterGroup’s technical specialists deliver scheduled and project‑based chemical cleaning services to improve operational efficiency, optimise energy usage, and reduce the risk of unplanned outages, regulatory issues, or premature equipment failure.
We design and execute end-to-end chemical cleaning programs – from pre-commissioning flushes to degassing, pickling and de-fouling.
Our services include:
- Vessel and pipeline decontamination: Safe and thorough removal of hydrocarbons, process residues and hazardous contaminants to prepare assets for inspection, maintenance, or repurposing.
- Acid and caustic cleaning: Targeted chemical cleaning using pH-specific agents to dissolve mineral scale, corrosion, or organic fouling from internal surfaces without damaging the equipment.
-
Pre‑commissioning and commissioning chemical cleaning
Removal of construction debris, mill scale, oils, and contaminants from new or modified systems to support safe start‑up, reduce early‑life corrosion, and achieve design performance from day one. - Surface treatment, pickling, and passivation: Preparation and protection of stainless steel and alloy surfaces to restore corrosion resistance – especially critical in food-grade and high-purity environments.
- Infield chemical analysis and waste neutralisation: On-site testing and adjustment of cleaning solutions, followed by safe neutralisation and disposal of chemical waste in compliance with environmental regulations.
Safety, compliance and environmental assurance
All chemical cleaning activities are delivered under strict safety and environmental controls, with documented procedures, risk assessments, and site‑specific controls in place. InterGroup operates in compliance with relevant regulations and client requirements, ensuring protection of personnel, assets, and the environment throughout the cleaning process.
Specialist capabilities
- Shutdown, turnaround, and outage support
Delivery of chemical cleaning services during planned shutdowns and turnarounds, aligned with maintenance schedules to minimise downtime, accelerate inspections, and support efficient restarts. - Corrosion control and asset life extension
Chemical cleaning programmes are designed not only to remove existing contamination, but to reduce ongoing corrosion risk and extend asset life through controlled cleaning and surface conditioning. - Tailored programme design
Every system presents unique challenges. InterGroup’s qualified chemists and experienced field crews assess materials, operating conditions and contamination types to develop fit‑for‑purpose chemical cleaning programmes that deliver effective results without compromising safety or asset integrity.
Why InterGroup
Our team of qualified chemists and experienced field crews tailor safe, effective programmes with minimal downtime. When combined with our own waste processing facilities, InterGroup provides a true cradle-to-grave service.
