Decoking Systems Features and Benefits
The basic control system includes a master control panel located near the pump train, a cutting deck panel for each pair of drums, and upper and lower proximity switches to monitor crosshead travel and tool position inside the drums. The system designs meet international standards and unique end-user requirements.
The system provides:
- Monitoring of the pump train and lube oil system with permissive starts, vibration and temperature alarms and shutdowns
- Safety interlocks for the drill stem, decoking valve and isolation valves
- Disabling of the hoist at safe high and low in-drum positions when cutting is in progress
- Display of cutting tool elevation and drill stem position
- Hoist cable tension with under and over tension set points that disable hoist movement
- Discharge pressure of the pump
- Speed indication of the rotary joint
Various options are available for improved system operations, including:
- Remote panels for the programmable controller and the condition monitoring system
- Triple modular redundant processors
- DCS communication
- Flowserve IPS APEX™ drum monitoring to assure complete cutting
- Remote and automated cutting capabilities
