The search and diagnostic analytics capabilities of TrendMiner can be used to find behaviors of interest. These behaviors can than be fingerprinted and used for monitoring purposes:
- Monitor that the process is performing in accordance with a specific fingerprint. For instance, detect whether a batch process starts deviating from the golden batch envelope.
- Detect when process or asset behavior matches a fingerprint of anomalous behavior.
Fingerprints can be created for batch processes, grades and continuous processes.
Manage by exception
Often a range of displays with key variables are periodically inspected by the engineering staff to verify the health of key process units or equipment. For instance, a periodic inspection may reveal the degree of heat exchanger fouling and trigger a maintenance action. Due to the number of potential issues, it can be cumbersome to manually inspect trends this way. As a result, problem evolutions are not always detected in a timely manner.
With TrendMiner monitor, data inspection tasks can be automated and the plant can be managed by exception, starting from an inbox with detections of interest.
“Production losses are typically shown by flare increase, which is an indication of leaking valves. Through a TrendMiner monitor, preventive maintenance helps us avoid multi-ton product losses.”
