Estimation of the Air-Demand, Flame Height, and Radiation Load from Low-Profile Flare using ISIS-3D

October 22-24, 2007 – Waikoloa, Hawaii

Overview:

• Introduction to ISIS-3D and flare modeling
• SIS model setup and methodology
• Low profile flare tests
• Model validation
• Burner predictions
  • Air demand
  • Radiation load
• Observations and conclusions

Single-Burner Mesh

• Rectangular cells
• Local refinement near burner tip
• 110,000 computational cells

Field Results

• ISIS-3D model
• Modeled flame shape/size for 3 fuels for single and three burner tests
• Predictions compared to data from 12 tests (2 tip sizes, 3 operating pressures, 2 radiation sample locations)
• Predicted “reasonable” estimates of radiation heat transfer and air demand for low profile flare
• Calibrated flare model applied to full-flare field to estimate
