Guidance on Flare Locations
Guidance on Flare Locations
(OP)
Does anyone know what codes govern the location of elevated, industrial flares? I see a minimum of 200 ft from process equipment a lot of places but no references.
Thanks for the help,

RE: Guidance on Flare Locations
Here are the ones I found on the list that appear to relate to Refinery installations in one way or another.
NFPA 30 Flammable and Combustible Liquids Code
NFPA 59A Standard for the Production, Storage, and Handling of Liquefied Natural Gas (LNG)
NFPA 214 Standard on Water-Cooling Towers
NFPA 274 Standard Test Method to Evaluate Fire Performance Characteristics of Pipe Insulation
NFPA 275 Standard Method of Fire Tests for the Evaluation of Thermal Barriers Used Over Foam Plastic Insulation
NFPA 307 Standard for the Construction and Fire Protection of Marine Terminals, Piers, and Wharves
NFPA 326 Standard for the Safeguarding of Tanks and Containers for Entry, Cleaning, or Repair
NFPA 400 Hazardous Materials Code
NFPA 820 Standard for Fire Protection in Waste Water Treatment and Collection Facilities

Based on my experience: Get it (the Flare Stack) as far away from everything as you can. That means anything inside the fence (Property line), outside the fence and the fence itself.
On one project I located the Flare on an island in the middle of the Storm Water retention Pond. The island was connected to the shore by a causeway that carried the pipeway, piping and a maintenance access road. The Flare KO Drum was on shore before the causeway.
prognosis: Lead or Lag

The same thing applies to trees or wooden buildings needing to be a certain distance away.

Also: There's usually a good reason why everyone does it that way

RE: Guidance on Flare Locations
You also usually need a blackened zone of 2.0 to 2.5 times the stack hight around the base of the flare.
