CPC Taoyuan, Taiwan

First liquid ejector FGR system in the world with automatic Hijector® and pump staging up and down based on flare header pressure with a nominal capacity of 5.8 MMSCFD.

  • Hijet delivered actual capacity of over 15% above the design requirement.
  • One area with a total of 2 trains, each train consisting of 2 Hijectors®, 2 pumps, 2 heat exchangers, 1 separator.
  • No shutdown of the system since commissioning 2 years ago.
  • Maintenance is limited to cleaning the motive liquid filters due to a significant particle content from the flare header.
  • Refinery has been able to achieve practically zero flaring.
  • Refinery has not used any anti-foaming chemicals in the amine absorber column because the sour water motive liquid Hijector® system washes the gas of any particles and absorbs CO2 and NH3 before sending the gas for amine treatment.

CPC Talin, Taiwan

Largest liquid ejector FGR system in the world with a nominal capacity of 18 MMSCFD.

  • Hijet delivered actual capacity of over 30% above the design requirement.
  • 2 separate areas with a total of 4 trains, each train consisting of 2 Hijectors®, 2 pumps, 2 heat exchangers, 1 separator.
  • No shutdown of the system since commissioning 2 years ago.
  • Maintenance is limited to cleaning the motive liquid filters every 8 hours due to significant particle content from the flare header .
  • Refinery has been able to achieve practically zero flaring.
  • Refinery has not used any anti-foaming chemicals in the amine absorber column because the sour water motive liquid Hijector® system washes the gas of any particles and absorbs CO2 and NH3 before sending the gas for amine treatment.
