For a typical, world-scale ethylene complex with 10 furnaces producing 800 kMT/yr, the potential benefit for the SmartProcess Ethylene Furnace solution is estimated to be more than $2.5 million per year. These benefits primarily come from the following sources:
- Longer furnace run lengths
- All passes coke at same rate
- Estimate 1 extra day of run length per furnace
- Improved ability to meet production plan
- Better visibility into the furnace operation, coking and yields
- Improve planning margin 0.2%
- Reduced unplanned furnace downtime
- 4 hours less downtime per year per furnace
- More stable and reliable operations
- 0.1% ethylene yield improvement.
- Control heater charge rate to a target or operate at a maximum limit
- Control heater severity for maximum yields
- Control a target dilution steam ratio for each pass
- Balance the loads on each pass to equalize the coking rate across the furnace
- Control excess air to maximize energy efficiency
- Maintain the furnace within all process operating limits
- Manage start/stop/decoke transitions for safe, consistent and efficient operations
