Improving Reformer Efficiency and Safety
Reformer and Cracker furnaces are critical equipment in petrochemical refineries. Maximizing the efficiency of the production process, while minimizing system downtime and safety issues, is a primary concern for plant operators.
Common concerns within these processes include proper tuning of the burner firing efficiency and maintaining the furnace tubes at the correct temperatures to prolong the life of the tubes. The objective is to minimize variation in tube wall temperature (TWT) and operate at a higher outlet temperature (ROT) without violating maximum allowable TWT.
Conventional methods of monitoring include portable pyrometers, portable thermal imagers, and shielded Type-K thermocouples. However, these methods have been proven to be unreliable, expensive to implement, prone to operator variation, and do not provide comprehensive ability to detect hot spots.
"Indirect" measurement using FurnaceSpection™ for Reformers & Crackers
Network of specialized thermal imagers designed for continuously viewing inside tube furnaces.
- Precise measurement of the temperature distribution on the parts (high camera resolution of 640 by 480 pixels).
Real-time thermal imaging software LumaSpec™ RT
- Real-time analysis and display of temperature data (e.g. HotSpots, Isotherms).
- Software collects streaming thermal data from cameras and continuously calculates TWT for display to operator and output directly to DCS.
- Systematic monitoring of user-defined regions with automatic alarming mode.
- Integration into an existing company network via Ethernet, and possibility of connection to a PLC.
Improves system performance while reducing potential process and safety risks.
- Increase profits by increasing output and lowering operating costs.
Lower maintenance & repair costs.
Allows for greater control and safer operations at optimum temperature.
