Marnix Vermeersch

A chemistry consultant in various sectors of the industry, Marnix focuses on water treatment in power plants. In his current position, he manages technical research programs in the area of water & steam cycle chemistry but is also experienced in areas such as demineralized make-up water and closed component cooling chemistry. His tasks mainly relate to carrying out chemistry consultation work onsite and emergency assistance with chemistry incidents. He is also skilled in plant chemistry management and training.
Before joining ENGIE Lab Laborelec, Marnix worked for 24 years as chemistry manager for the ENGIE conventional power plant fleet in Flanders, Belgium. In addition to the chemistry of water treatment, he has built up knowledge and experience in combustion chemistry and the chemistry of lubricants, making him an all-round power plant chemist with water/steam cycle chemistry as his principal expertise and current work domain.
Marnix was contracted for two years by ENGIE Electrabel to lead chemistry related projects and is still involved in chemistry projects in ENGIE nuclear power plants.

Anthony Senécat

Anthony Senécat is chemistry consultant in the energy sector. His main customers are operators of power plants and of industrial facilities. In his present position he is active in the water-steam cycle chemistry field where he provides support to increase chemistry maturity through audits, trainings or development of key performance indicators. His duties also include missions of operational assistance in the field of chemical cleaning and troubleshooting. More recently, he expanded his field of competence towards electrical storage. In this regard, he specializes in electrochemistry and is in charge of different tests on batteries and their components within the ENGIE Batteries Lab.



This course is about the chemical aspects of the water-steam cycle in a power plant. Included in the program are the different types of chemicals used in boilers, potential issues in a water-steam cycle, monitoring and specifications regarding target values and alarm levels. Actions in case of chemistry-related incident are also part of the course.


The course includes the following aspects:

  • detailed aspects of chemistry in a water steam cycle, such as types of chemicals used in the boiler depending on the treatment and type of boiler,
  • potential issues in a water-steam cycle, such as corrosion and deposition
  • monitoring and analytical programme, and knowledge of the specifications for the water steam cycle (normal values targets – alarm levels)
  • chemistry aspects during transition periods: start-up, shutdown and preservation
  • actions in the event of an alarm
  • examples of incidents or deviations compared to normal chemistry

The last part of the course is dedicated to exercises and a quiz.

Target Audience

The course addresses a wide audience, including operators, power plant chemists, plant operation or maintenance engineers, consultants and technical project managers.

Practical Info

Please note that the mentioned dates are subject to change if the required number of participants is not met. If interested in the training courses but the proposed dates do not suit your schedule and would like to be enrolled on a waiting list, or if you would like a dedicated session for your team (on-demand), please get in contact at

When organizing a hybrid delivery session, the training course will have attendees joining a live-classroom session (hosted at our offices in Linkebeek, Belgium, assuring the necessary health & safety measures) and attendees joining the same session but in a remote live-online manner.

For attendees joining a live-classroom session at our location, an extra fee of 60 EUR/training day will be added, covering the catering aspects of the training delivery.
