Johnson Controls - Boil-Off Screw Compressor

What is a BOG? Why does a BOG need to be accompanied by a compressor? And why an FMM

What is LNG? Almost everyone can answer that. What is BOG? Well, this is where not everyone can answer. BOG (Boil-Off Gas) is the evaporation of LNG or other liquefied gases (such as hydrogen/nitrogen) stored in a tank. This is caused by heat leakage from the surrounding environment. This occurs during storage, transportation, loading, or unloading and will increase pressure inside the tank if not managed.

This advanced processing process requires a BOG compressor to ensure the safe and non-hazardous transfer of gas. A BOG compressor works by drawing vaporized gas (BOG) from an LNG storage tank, increasing its pressure using mechanical energy, and then returning it to the system (re-liquefaction, fuel, or pipeline) for efficient utilization and maintaining safe tank pressure.

Johnson Controls (JCI) BOG Screw Compressor

Johnson Controls (JCI) BOG Compressors are an international brand distributed in Indonesia by PT Fajar Mas Murni (FMM). The quality of JCI BOG Compressors aligns with the reputation of FMM as its distributor.

Stages and Working Principles of JCI BOG Screw Compressor:

• Suction: Cryogenic (very cold, down to -160°C) LNG from the LNG tank is sucked by the compressor through the suction line.
• Compression: The gas is compressed using a centrifugal compressor to increase its pressure.
• Cooling: JCI compressors have multiple stages separated by intercoolers to maintain a safe gas temperature during the pressure increase process.
• Discharge: The highly pressurized gas is pushed to the destination system, namely the Re-liquefaction Unit, Fuel System, or Distribution Pipeline.
• Control: An Anti-Surging Valve is used to prevent backflow and ensure the compressor operates safely.

The main benefits of the JCI BOG Screw compressor are:

• Prevent Overpressure: Reduce pressure in LNG storage tanks to prevent explosions.
• Economic Efficiency: Convert waste gas into energy or liquid products.
• Reduce Emissions: Minimize greenhouse gas emissions into the atmosphere.  

On this occasion, FMM offers the JCI screw compressor, as the best solution for BOG processing needs in Indonesia.
