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.

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.
