• The visual flare is a sign of wasted resources
  and pollution
• FLARE GAS RECOVERY SYSTEM eliminates the need for
  continuous flaring of gas on oil and gas
  producing facilities and petrochemical plants
• By using this systems we can recover VALUABLE
  flare gases, compressing them back into the plant
  for use as feedstock, fuel or product.
• This technology also reduces plant emissions of
  combustion by-products such as NOx, CO, and CO2.

Reduce. Recover. Reuse.

• Flare gas recovery benefits
• Environmental Control With Serious Payback
• Reduced facility emissions
• Reduced purchase gas requirements and/or
  increased salable gas
• Extended flare-tip life
• Reduced steam consumption

According to the Kyoto Protocol

• projects should result in
• Real, measurable and long-term benefits related
  to the mitigation of climate change reductions
  in emissions (Art. 12, 5, bc).

share of total gas produced has been reduced by a
factor of 4

Possible sources of unknown flare flow

• Relief valves or PSVs will leak due to
  corrosion, fouling, or from mechanical damage.
• Block valves can seal poorly due to any number
  of problems,including normal wear of the valve
  seat.
• Poor pressure control causing cyclic pressure
  swings can cause a rupture disk to lose its seal,
  or a relief valve to chatter damaging the seat
  of the valve.
• Higher than normal operating system backpressure
  due to fouling will cause some systems to relieve
  intermittently.
