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.
As part of our participation in the upcoming World Nuclear Energy Exhibition, which will take place in Villepinte from 4 to 2 November 2025, we have been nominated in the ‘To boost Nuclear Installation Performance and LTO - Small companies’ category of the WNE Innovation Awards 2025.
We will soon be exhibiting at Pollutec, stand H4-B095.
A leading showcase for environmental innovation, with 45 years of expertise and 11 sectors covering all environmental issues, the exhibition highlights all the technologies, solutions and equipment dedicated to the prevention and treatment of all forms of pollution and works to preserve the environment and implement sustainable development.
We exhibited for the first time in the ENERH2O on September 24 & 25th, Portugal’s leading energy and water exhibition. This third edition presented the latest solutions and innovations for the management and use of these essential resources, with a focus on energy efficiency, renewable energy production, and sustainable water management.
