SECTOR PROFILE 01 OF 04

Oil Refining & Petrochemicals

Crude Preheat Fouling Analysis, Distillation Columns & Energy Recovery

I assist refinery and petrochemical engineering teams in quantifying crude preheat train fouling penalties, optimizing atmospheric CDU towers, and designing heat integration networks that cut furnace fuel costs.

Thermal Bottlenecks:
  • •Severe preheat exchanger fouling forcing fired heaters to burn excess fuel
  • •Fired heater bridge wall temperatures approaching metallurgical limits
  • •Sub-optimal Pinch topology across atmospheric and vacuum distillation trains
How I Intervene:
  • ✓Aspen HYSYS & Python automated fouling rate monitoring and cleaning triggers
  • ✓Pinch Analysis heat exchanger network retrofits adding avoided fired duty
  • ✓Aspen EDR shell-and-tube thermal-hydraulic rating and vibration mitigation
Efficiency Gain9% – 29% Duty Penalties Saved
CO2 Impact6,000 – 15,000+ t/yr CO2
Typical Payback6 – 12 Month Payback
