Alliance - Elevated Flares

Basis for design of flare:

• Specifications Analysis
• Gas Analysis
• Hydraulic & Noise Analysis
• Radiation & Flame Analysis
• Pressure Drop
• Exit Velocity
• Structural Stability. 

Flare Tips

Flare tips are available in various solutions, both in smokeless and non-smokeless operations. Flare gas must always have a minimum heat content in btu / scf:

• Steam-assisted – 300 btu/scf
• Air-assisted – 300 btu/scf
• Non-assisted – 200 btu/scf

Steam-assisted and non-assisted flares:

• 300 Btu/scf = 60 fps maximum
• Greater than 1,000 btu/scf = 400 fps maximum 

Dispersion and toxic analysis:

Dispersion is performed on vent gases or flare gas in the event of loosing the flame on the top of the flare system. Under this scenario, the analysis will exhibit the vent plume coordinates and concentrations of hydrocarbon components in the plume.

Flare Design Standards and Guidelines :

• API 521
• API 537
