FLare Stack

®
Production Testing Solutions
TETRA’s Flare Stack is used to dispose of gas during land operations for cleanup and initial flowing operations. The flare stack allows gas
to be burned at a safe distance from the work area and is elevated to assist the dispersion of combusted fumes, protecting workers and the
environment. Flare Stacks are also required for hazardous environmental gas disposal such as H2S and is used as the relief flow disposal point
when relief lines are extented for safe operations. All flare stacks are equipped with a gas pilot system and electronic auto ignition system. Sizes
and heights range from 45, 60, 80, and 160 feet high. Most flare stacks are hydraulic or electrical winch-operated to vertical positiion for easy
rigup. The 100' and above require a crane.

Features
• Allows temporary disposal of gas during cleanup operations
• Continuous pilot light to ensure gas flare ignition
• Reduces carbon emissions
• Reduces noise emissions
• Maintain safe distance during flow of hazardous gases
• All TETRA Flare Stacks have condensate pots at the base of the flare stack for the
accumulation of drip gas
• Optional gas-free pilot with continuous solar-powered ignition source
• Optional incineration nozzles that enhance burn quality

Benefits
• Onshore flowback and well cleanup
• Disposal of hazardous gases, such as H2S
• Used for relief vent piping away from the area where personnel could be in danger
• Green completions require total burn of all vented gases
• Wellsite intervention services
