A major actor of the chemical and petrochemical world industry in South America and the United states has consulted CTP ambiental to by-pass its BIOX station located on Rio de Janeiro, currently dealing with effluents issued from its production of both thermoplastic resins and of polypropylene.

Our client, a major player in the production and supply of electricity in Newfoundland and Labrador (Canada), handles the generation and distribution of 80 % of the energy consumed in the province.

Steam condensers in nuclear power plants are made up of several smaller condensers, which themselves comprise approximately 21,000 metal tubes circulating cooling water. Due to the hardness of water drawn from the natural environment, the cooling tubes are subject to regular and significant scaling and need to be cleaned using ultra-high-pressure water jets (UHP).

CTP environnement’s teams were contracted to clean a 12 m (39 ft) long and 4 m (13 ft) high heat exchanger, which equated to approximately 2 tons of residue, primarily made up of calcium carbonate (CaCO₃).

A major player in all areas of the construction sector - property development, design and construction of all kinds of buildings - contacted CTP environnement for the treatment of groundwater on a former industrial site before discharging it into the municipality’s sewage system.

Every year, our client cleans the water loop on its production site to:

• Comply with the statutory requirements for cooling towers
• Restore the steam condenser performance to its original level

A large steel-making complex asked CTP environnement to solve a recurring problem: because of an extremely dusty environment, the air side of air-cooled heat exchangers used for cooling oils become clogged and less effective.

France’s largest refinery asked CTP environnement to clean 4 furnaces within the site’s cracking unit. Due to the use of fuel that causes clogging, these facilities require regular maintenance to recover design operating data.

A refinery in south-east Asia suffered torrential rain during the monsoon season. A Remote Impounding Basin (RIB) is used to handle the stormwater runoff, prevent flooding and pollution of the nearby environment.
The refinery issued a call for tenders, in order to find a company able to further treat this contaminated rainwater stored in the RIB in line with the applicable discharge standards.

Our client, a leading player in the chemical industry, asked CTP environnement to carry out mechanical cleaning of the cooling tower for the water supplied to its workshops, and to clean the tank (not including pumping out).

Our client, a major player in the refining industry, asked CTP environnement to clear out the final tank located close to their plant. The discharged effluent had created a build-up of sludge at the bottom of the tank of around 120 m³ (157 yd³) with 35 % dryness (estimate for an area of 200 m² /2153 ft²). After draining and treating the supernatant water, the sludge accumulated at the bottom of the tank needed to be cleared and dewatered.

A major French automotive group asked CTP environnement to identify the best available technology for treating their treated effluent. The goal was to be compliant with requirements governing discharges of hazardous substances into water (French RSDE regulation), especially the metals traces.

An oil refiner recognised the need for chemical cleaning of a water side steam generation boiler as part of its maintenance programme.

An LNG (Liquefied Natural Gas) plant contacted CTP environment Asia Pacific for a 2 years contract for air fin coolers online cleaning.

A world class sugar industrial, based in France and in several other countries (Brazil, Romania, Indonesia, etc.), has asked CTP environnement to design and set up a mobile solution to treat effluents from production campaigns (beet base).
