Flare Stack

Flare gas stacks, also known as flue gas stacks or exhaust stacks, are tall, cylindrical structures used to discharge waste gases from industrial processes into the atmosphere. In surface well testing, gas flaring is conducted by 40 ft, 60 ft, or 90 ft flare stacks. Flare systems are available in 3”, 4”, 6” & 8” in diameter, which can be mobile and installed on a trailer. Trailer-mounted gas flares are very convenient to be mobilized, installed, and operated. Gas flaring systems consist of multiple pilot gas lines, automatic ignition system, flare tube, flare tip, and other components necessary for safe and reliable operation.

Applications:

  • Onshore well testing and flow back
  • Petroleum refineries, chemical plants, and natural gas processing plants
  • Production projects

Features and Benefits:

  • Skid or trailer mounted
  • Integral ignition system with automatic re-ignition
  • Multiple lines configuration
  • NACE MR0175
