Chemical processes
suitable for all kinds
of heat exchangers
Our chemical treatments are specially designed to clean the majority of industrial heat exchangers (shell and tube, plate, coaxial) made from materials such as stainless steel, carbon steel and other alloys (copper, titanium, etc.), on both of the relevant sides.
We have developed suitable chemical processes for removing build-ups, including limescale, salts, metal oxides and biofilms, as well as organic hydrocarbon deposits.
Our chemical cleaning services include:
Immediate results
The aim is to restore the thermal capacities of heat exchangers, while maintaining the integrity of equipment.
Depending on the circumstances, this improved efficiency results in an increase in the flow of cooling water, a reduction in the circuit’s pressure loss, an improved process fluid temperature and, in all cases, a rapid return on investment.
Proven responsiveness for online and offline operations
The availability of specially designed compact cleaning skids facilitates a rapid response, thereby reducing downtimes.
We have also developed a specific process for cleaning certain heat exchangers that are more critical than others (Optiflow® process) without stopping production.
This application, combined with online cleaning of fired heaters or air-cooled heat exchangers/air-cooled condensers (Neutramex® process), as well as online cleaning of heat exchangers in the preheat train, facilitates the “debottlenecking” of production units, including atmospheric distillation and vacuum distillation.
Chemical cleaning of a heat-exchanger
A thermal power plant in New Caledonia asked CTP environment Asia Pacific to carry out chemical descaling of a steam condenser.
CTP environment Asia Pacific developed an optimum chemical cleaning procedure, which incorporated effectiveness, in terms of the residue to be dissolved, as well as protecting the integrity of the materials exposed.
To accelerate its international growth, CTP environnement group has embraced the V.I.E program, led by Business France and backed by the French government. For several years, qualified young talents have been strengthening our teams in subsidiaries located in Singapore, Canada, the USA, and more recently, the United Kingdom.
In our American subsidiary based in Houston, Neyl stood out brilliantly by winning first place at the V.I.E Grand Prix Americas 2025, an award that recognized 4 winners out of 97 candidates. His original and impactful video—highlighting France as THE go-to destination for innovation and investment—made all the difference.
We took part for the first time in the 24th edition of INTERSOL, the International Congress and Exhibition on Soils, Sediments and Water.
Our teams came to meet the leading players in the field of polluted sites and soils (PSS), to compare their challenges and solutions, and to respond in the best possible way.
BPI France has been supporting our development for many years, even before the creation of our nuclear division in 2015.
10 years later, on the strength of our recent experience, which has been recognised by major players in the sector, we decided to join their Nuclear Acceleration Programme, launched in 2024.
