    Habshan Flare Gas Recovery Project

    The Habshan Flare Gas Recovery Project (HFGR Project) is intended to recover hydro carbon gas from each of the Habshan 0, 1, and 2 hydrocarbon flare headers during normal operation (up to a rate of 5 MMSCFD per header) with a total of 15 MMSCFD for all three units. Gasco has undertaken this project mainly to provide a cleaner environment.

    At present Flare gas from the plants is routed through Flare Knock out (KO) drum to their respective flares. No water seal drum is provided in between flare KO drum and flare stack. To prevent any back flow of air through the stack, a positive pressure is maintained by purging the flare header with fuel gas.

    New water seal drum and associated downstream purge connections at Flare Knock out drum downstream will be provided for each of the hydrocarbon flares. Upstream of water seal drum a new 1 x 100% train of flare gas compression will be added with a capacity of 5 MMSCFD each. Compressed recovered flare gas will be routed to existing compression units 13 and 113. Recovered oily sour water will be routed to existing sour water treatment units 72 and 172.

    Current flow to hydro carbon flares are as follows:

  • Habshan 0 - 0.8 – 1.1 MMSCFD
  • Habshan 1 - 0.8-1.5 MMSCFD
  • Habshan 2 - 0.5 – 0.8 MMSCFD
  • Total - 2.1 – 3.4 MMSCFD


  • Estimated total purge flow after completion of HFGR project is 0.55 MMSCFD (0.15+0.21+0.19).
    Thus the amount of gases flared will be reduced by an average of 1.5~2.85 MMSCFD
