Furnace Efficiency Prediction
Challenge
Ethylene furnaces coke (foul) during cracking operations resulting in a loss of efficiency
Improper decoking resulting in equipment damage and lost production time
Solution
Identify different phases of decoke operation and excessive hold times
Predict decoke effectiveness with KPIs like temperature recovery and run time between decokes
Result
Tracking decoke effectiveness metrics identified procedural inefficiencies and inconsistency in execution
Optimization of decoke procedures reducing hold time and dead time has resulted in an additional $250k/y in production.
