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.
