Special Chemical Cleaning

AEKS provides custom-engineered chemical cleaning services for a wide range of process and utility systems, including heat exchangers, pipelines, boilers, reactors, cooling systems, and closed-loop circuits. Our approach is based on a deep understanding of system metallurgy, deposit chemistry, and operational parameters, allowing us to select and apply precisely formulated chemical solutions that target and dissolve scale, corrosion by-products, biofilm, organic contaminants, polymer fouling, and residual process media.

Each project is preceded by a detailed technical assessment, including system layout analysis, sample collection, and laboratory testing when needed. Based on this, AEKS develops a tailored cleaning protocol, which may include acid descaling, alkaline degreasing, oxidizing or non-oxidizing biocide treatment, solvent flushing, or neutralization sequences, executed via chemical circulation (recirculation loops) or fill-and-soak techniques under controlled temperature and flow conditions.

We utilize automated dosing and monitoring systems to ensure safety, control reaction kinetics, and achieve optimal cleaning efficiency—while minimizing waste and ensuring compliance with environmental and safety regulations.

Pre-operational chemical cleaningis a critical step in the startup phase of new or refurbished process systems. These cleanings are designed to remove construction debris, weld slag, grease, oils, rust, mill scale, and other contaminants that accumulate during fabrication and installation. This procedure ensures that systems start in a pristine condition, minimizing the risk of early operational issues such as clogging, corrosion, or performance degradation.

Typical systems treated include:

By removing residues before startup, pre-operational cleaning supports stable commissioning, reduces the likelihood of unplanned shutdowns, and extends the life of the equipment from day one.

Maintenance chemical cleaningis a best-practice procedure aimed at restoring system performance during routine plant operations. Over time, systems accumulate scale, organic fouling, microbiological growth, and corrosion products that degrade thermal efficiency, reduce flow rates, and accelerate wear on critical components.

Scheduled maintenance cleanings help:

The required frequency and procedure of maintenance cleaning depend on system design, operational conditions, process fluids, and historical fouling rates. AEKS performs representative tube sampling, deposit analysis, and metallurgical evaluations to determine the most suitable cleaning chemistry and method for each application.
