Aibel - Flare Gas Recovery, Flare Gas Ignition, HydroCarbon Blanketing, Recovery and Compressor Packages

Aibel AS aims to develop and to supply systems reducing emissions to air from gas, oil and petrochemical installations.

Aibel has a significant experience in technology associated with gas recovery and compressor technology on offshore and onshore installations.

FLARE GAS RECOVERY SYSTEM

• In accordance with API RP 521
• Easy and safe recovery of the flare gas
• Environmentally friendly
• Substantial reduction of CO2 and NOX emissions
• Cost effective solution
• Increased flare tip lifetime

The flare gas recovery system eliminates the need for continuous flaring of gas, thereby saving gas, reducing emissions of CO2 and NOX and extending the lifetime of your flare tips.

The concept comprises flare header isolation equipment, a passive and/or active flare gas recovery system, control logic and a reliable ignition system, e.g. the Safe Ignition USIS-130 or USIS-2000.

This technology has proven itself during years of operation installations in the North Sea.

FLARE GAS IGNITION SYSTEM

• Appropriate for all weather conditions
• Suitable for all flare tips
• Easily retrofitted into existing installations
• Improved safety
• Ballistic spark ignition
• No electronics in area of high heat radiation
• No pilot burners

Our flare ignition systems were developed to guarantee safe ignition in all weather conditions.

Aibel offers a unique method of igniting flare gas, which eliminates the need for pilot flares. Specially designed pellets are launched through a guide pipe. When the pellet reaches the flare tip it bursts and generates a shower spark igniting the flare.

Aibel supply two different models of the ignition system:

Safe Ignition USIS-130 - automatic high pressure, nitrogen driven system. Due to the high detonation velocity the maximum range of this system is 130m.

Safe Ignition USIS-2000 - Automatic or manual low pressure, air driven system. The system can be used in any installation with remote flares as the maximum range for this system more than 2,000m.

VAPOUR RECOVERY SYSTEMS

Aibel supplies vapour recovery systems for a number of applications based on the principle of absorption and membrane separation. The systems is designed to collect and liquefy up to 99% of hydrocarbons in a single stage and requires only electric power and cooling water. The system does not create new emissions or contaminated waste.

For FPSOs and shuttle tankers, Aibel offers proprietary technology for using hydrocarbon gas as blanketing gas in the crude storage tanks.

COMPRESSOR TECHNOLOGY

Aibel is an established supplier of compressor and ejector systems. Recently deliveries include variously types of: oil-filled screw compressor, liquid ring compressor, roots blower type and gas ejectors for the oil and gas industry.

Typical applications:

• Flare gas recovery
• Vapour recovery
• VOC recovery
• Fuel gas compressors
• Hydrocarbon blanket gas
• Nitrogen compressors
• LP compression (first stage recompression)

As a process system supplier, Aibel has the knowledge and expertise to design the process modules and control strategies around the compressors or ejectors to ensure trouble-free and efficient operation.

PROCESS ENGINEERING

Aibel conducts studies related to its product range, power optimisation and CO2 reductions.

The scope of these studies varies from screening studies to FEED (Front End Engineering Design) studies comprising equipment costing, installation costing, and risk and safety analysis.

Aibel has performed comprehensive studies within power optimisation and CO2 reduction on major offshore fields like Gullfaks, Statfjord, Sleipner and Ekofisk. Typically this work involves preparing models and conducting simulations using software such as Hysys, Pro/II and Proprietary in-house programmes.

As part of its process services Aibel can provide skilled Hazop managers conducting the Hazop study.
