APPLICATION ENGINEERING GUIDE
Refinery and petrochemical heat recovery
Evaluate heat recovery using matched hot- and cold-stream data. This guide describes an engineering workflow, not measured customer savings.
- Existing unit and duty
- Provide the current heat balance, stream properties, flow rates, inlet and target outlet temperatures, and operating range.
- Problem to assess
- Separate thermal limitations from fouling, pressure-drop limits or process variability. Identify usable heat demand as well as available waste heat.
- Scope and material
- Compare a new recovery duty, plate-pack replacement and complete-unit replacement as applicable. Include piping interfaces, cleaning access and compatible wetted materials.
- Verification
- Confirm the thermal balance and pressure drop for the specified operating cases. Review fouling allowance, maintenance requirements and instrumentation for acceptance.
- Result to establish
- Use measured flow and temperature data to verify recovered duty after commissioning. State energy or cost savings only when the baseline and operating data support them.
