Flare Gas Recovery Unit (FGRU)

• TI-FGRU-LR1 – two liquid-ring compressors, each sized for 100% of design flow (2 × 100%).
• TI-FGRU-LR3 – a larger unit with three liquid-ring trains, each sized for 50% of design flow (3 × 50%).

• Compressor type: liquid-ring, designed to API 681 or client specification
• Train arrangement: 2 × 100% (TI-FGRU-LR1) or 3 × 50% (TI-FGRU-LR3)
• Capacity: sized to the flare header base load, or to client specification
• Discharge: to fuel gas or process, with pressure to client specification
• Service liquid: selected to suit the gas, or to client specification
• Materials: to suit the gas composition, including sour service, or to client specification
• Vessels: designed to ASME VIII or client specification
• Controls: PLC with header pressure control and compressor staging

Why liquid-ring compressors?
They tolerate wet, dirty and changing flare gas, including sour gas, which is why they are the industry standard for flare gas recovery. They are designed to API 681.

What train arrangements are available?
TI-FGRU-LR1 with two liquid-ring compressors at 100% each, or TI-FGRU-LR3 with three trains at 50% each for larger flare headers.

How is the unit sized?
To the flare header base load, with the PLC controlling header pressure and staging compressors to follow the flow.

Which materials are used?
Materials suit the gas composition, including sour service, with vessels to ASME VIII.

Refineries, gas plants and production facilities send a steady base load of gas to the flare from relief valves, purges and process upsets. The FGRU recovers that base load while leaving the flare in place for emergency relief. Petrochemical plants and terminals use the same unit to cut flaring and emissions and to offset purchased fuel gas.

• Gas back into use – recovered gas offsets fuel gas or returns to process.
• Less flaring – lower emissions, less smoke and less flare noise.
• Handles wet gas – liquid-ring compressors tolerate liquids and dirt in the feed.
• Cool compression – the service liquid absorbs the heat of compression.
• Redundancy – 2 × 100% or 3 × 50% trains keep recovery running during maintenance.
• Flare safety kept – the flare remains available for relief at all times.
