Flare Gas Recovery

Flaring is an unproductive waste of a valuable, non-renewable resource and a significant source of carbon dioxide and methane emissions

To recover the wasted income from flared gas, EAJV Technology offers flare gas recovering technologies to recover valuable resources and reduce the flare gas to achieve near-zero flaring with the methods described below:

Processing the flare gas through either water injected screw compressor or liquid ring pump compressor:

The flare gas is compressed and the heavier hydrocarbons condense out. The collected amine and liquid hydrocarbons enter a gravity separator where the hydrocarbons are decanted off and the collected amine is sent back to process the amine solution. The relatively cleaned flare gas is then sent to a H2S removal system and then to the fuel header. The condensed hydrocarbons are again decanted out and sent to the liquid condensate tank. Upon failure of any component, the flare gas is then passed to the existing flare itself.

Processing the flared gas through a series of educators:

The flared gas recovery system consists of processing the flare gas through three educator system complete with all accessories especially designed to handle the flare gases. The flare gas pressure is increased and the heavier hydrocarbons condense out. After leaving the educators, the gas, amine and hydrocarbon mixture enter the Gas/Liquid separator where the compressed gas is separated from the amine and condensed hydrocarbons are separated by gravity due to the lower gas speed. The collected amine and liquid hydrocarbons enter a recirculation tank/separator where the hydrocarbons are decanted off and the collected amine is sent back to process the amine solution. The relatively partially scrubbed and cleaned flare gas is then sent to small tray section tower, where final H2S is removed and then the gas is to the fuel header. Upon failure of any component, the flare gas is then passed to the existing flare itself.

The advantages of our system are:

  • Dramatically reduce flare emissions (Near zero flaring)
  • Recover waste gases for fuel, thereby increasing sales gas
  • Prolong life of the flare system
  • Reduce operating cost
  • Improve public perception of operator
  • Producing transportable hydrocarbons through GTL or LNG plants
