Chemical cleaning Spheres / Tanks / Circuits / Columns / Reactors

All process equipment

Other process equipment also has specific requirements in terms of chemical treatments: degreasing, decontamination, passivation, neutralisation, etc.

This wide variety of equipment, in terms of both the process and its design, necessitates a case-by-case approach, which our engineers adopt when developing procedures.

Specific cases

Our range of services is not limited to conventional descaling of heat generation equipment, but also includes the following operations:

  • Descaling, deoxidation of enamelled steel double walled reactors
  • Aqueous phase decontamination
  • Vapour phase decontamination
  • Neutralisation of polythionic acids
  • Sulphide oxidation

A perfect combination of resources and technology

CTP environnement guarantees a controlled and well thought-out operation, by developing a specific procedure for the equipment in question and remaining aligned with the stated objectives.

Without controlling the hydraulics, powerful chemistry will come to nothing, which is why our engineers, technicians and operators work together to guarantee the best results.

Chemical circulation during a maintenance operation

Passivation of the steam generation circuit - fired heater for a steam cracker

Our client discovered holes in heat-exchangers within the steam generation circuit for 3 fired heaters of a steam cracker unit. He conducted thickness checks which revealed a loss in the thickness of tubes and the presence of corrosion on the hot side of one heat exchanger. After repairs involving metal work and boiler work, CTP environnement was contracted to carry out pre-passivation on couple pieces of equipment - two fired heaters and after the replacement of the third fired heater.
