Tank Vapour Recovery Unit (VRU)

• TI-VRU-S0.5 – screw-compressor skid for 0.1–0.5 MMSCFD.
• Single or duty/standby – one compressor, or two for sites that cannot vent during maintenance.
• Discharge options – to fuel gas, a gas gathering line or a flare gas recovery system.

• Capacity: typically 0.1–0.5 MMSCFD, or to client specification
• Compressor: screw type, motor-driven, with variable-speed control
• Suction: low-pressure tank vapour, held within tank design limits
• Discharge pressure: to suit the receiving system, or to client specification
• Materials: carbon or stainless steel to suit the vapour composition, or to client specification
• Hazardous area: electrical equipment selected for the hazardous-area classification, or to client specification
• Controls: PLC with suction pressure control, alarms and shut-downs

What vent flows does the VRU handle?
Typically 0.1 to 0.5 MMSCFD from crude, condensate and produced-water tanks, with the screw compressor on variable-speed control to follow changing vent rates.

Will it pull a vacuum on the tanks?
No. The PLC controls suction pressure and holds it within the tanks' design limits.

Where does the recovered gas go?
To fuel gas, a gas gathering line or a flare gas recovery system, at the pressure that system needs.

Can it run with a spare compressor?
Yes. A duty/standby arrangement with two compressors suits sites that cannot vent during maintenance.

Storage tanks give off flash gas and vapour as they fill and as the oil weathers. The VRU collects this gas at tank pressure and compresses it into a fuel gas, gathering or recovery system. Oilfield production stations, tank farms, export and product terminals, and refineries use it to cut emissions and odour while recovering gas that would otherwise be lost.

• Gas back into use – vented vapour becomes fuel or sales gas.
• Lower emissions – less vapour to atmosphere or to flare.
• Tank protection – suction control holds tank pressure within its limits.
• Wide turndown – variable speed and recycle follow changing vent flows.
• Compact skid – compressor, scrubbers, coolers and controls on one base frame.
