Preventing damage through remote water-steam chemistry supervision
WHY - Chemistry issues staying under the radar
WHAT - Signaling and addressing chemistry issues
Benefits and added value
ENGIE Laborelec chemistry experts deliver a continuous supervision service, remotely monitoring the water-steam cycle chemistry using intelligent digital tools. They provide proactive support in the event of a chemistry deviation. This means a more rapid response to chemistry incidents, leading
to long-term improvement. Monthly chemistry
KPI reporting also contributes to better risk management.
Unplanned shutdowns can cost up to €100,000 a day, while losses due to a major chemistry incident can run into the millions. Better chemistry management avoids all this. As well as preventing unplanned outages, top-class chemistry management reduces the need for chemical cleaning, generating recurrent savings of several thousand euros per year.
Regular exchanges with plant operators combined with yearly on-site visits by ENGIE Laborelec experts contribute to greater understanding and awareness of chemistry-related issues by power plant staff.
HOW IT WORKS
CHESS service working principle
HOW DO WE IMPLEMENT CHESS?
CASES FROM THE FIELD
The rhythm of the sea
He also concluded that the salt contamination was sufficiently limited that it could be dealt with first through drum blowdown. So, he was able to advise against an immediate shutdown, allowing the leakage search to be postponed until the next planned outage.
Costly intervention and an unplanned outage were avoided thanks to CHESS.
Service reveals multiple concurrent measurement issues
Avoiding counterproductive action
It was therefore necessary to first correct the caustic leaching problem, then drain and refill the demineralization tank, and finally open the blowdowns to evacuate the contamination. A clear example of how the CHESS service helps operators to make the right decisions.
