Chapter Summary:

• Purpose of flaring: Primarily safety; secondarily economics when micro‑flows are uneconomic to recover. Historically <1% of gas flared on mature platforms.

• Anatomy of a flare: Headers → knockout drums → flashback seals → flare tip (multi‑orifice, steam assist, pilot flame, igniter).

• Modern efficiency: Properly tuned systems achieve ~98%+ combustion and minimize soot.

• Takeaway: A steady flame is more than a beacon—it’s a safety valve for the entire plant.
