Decoking on-line monitoring system is applied to the hydraulic decoking process of the delayed coking unit. The signals from the vibration sensors are used to automatically determine whether the decoking process is complete inside of the coke drum, and translating into the visual display on the computer monitors to provide operators with real-time decoking data/progress.
This system is very simple to operate and helps refiners to decrease the cost of decoking, it effectively reduces the decoking time, improves the efficiency while ensuring the safety of the operators, minimizing the chance of accidents.
Decoking on-line monitoring system will ensure the progress/cleanliness of decoking process basing on scientific/instrumentation facts, and not just relying on operator’s experience or human vision/hearing.
Increasing production efficiency with the decoking on-line monitoring, vibration sensors can accurately determine the cutting progress, and reduce overall decoking time.
Reducing energy consumption, the system will shorten the decoking time by 15 minutes (0.25 hours) per coke drum.
Lowering the labor costs, reducing the dependency on operators’ experience, and simplifying the decoking process.
The system offers extra protections to safeguard equipment and personnel, removing personnel from the hazardous environment and accurately monitoring the decoking progress in the control room to ensure the safety of equipment and operators.
