Oil & Gas Vapor Recovery Units (VRU)
PollutionCtrl provides project-specific vapor recovery systems for storage tanks, tank farms, loading racks, terminals, refineries and process vents. The recovery route is selected from vapor composition, flow pattern, pressure, temperature, oxygen content, liquid carryover risk, product value and the required recovery destination.
Choose the right vapor recovery process
| VRU category | Typical fit | Main process | Review first |
|---|---|---|---|
| Condensation + Adsorption VRU | Tank breathing, loading vapor and heavier hydrocarbon streams where recovered liquid has value | Staged cooling, condensate separation, adsorption polishing and desorption | Vapor composition, dew point, water, peak flow, refrigeration and liquid handling |
| Adsorption + Absorption VRU | Gasoline, light hydrocarbon and variable vapor streams requiring concentration equalization and deep treatment | Activated-carbon adsorption with absorption, solvent circulation and optional regeneration | Hydrocarbon compatibility, absorbent selection, oxygen/LEL, temperature and tail-gas target |
Typical vapor sources
- Fixed-roof and internal-floating-roof storage tanks
- Truck and rail loading racks
- Marine loading and unloading terminals
- Refinery and petrochemical tank farms
- Methanol, gasoline, diesel and solvent storage
- Process vents, blending, sampling and transfer operations
Safety and engineering scope
A complete VRU review includes source classification, vapor-header pressure balance, liquid knockout and drainage, flame-arrestor protection, grounding, hazardous-area electrical design, LEL and oxygen monitoring, nitrogen blanketing where required, emergency isolation, bypass and control logic.
Data required for preliminary selection
Provide the minimum, normal and peak vapor flow, gas composition, molecular weight, pressure, temperature, oxygen and moisture, liquid carryover, tank or loading data, simultaneous operating cases, recovery destination, emissions target and available utilities.
VRU manufacturer, engineering and supply scope
PollutionCtrl supplies packaged vapor recovery equipment for oil storage tanks, truck loading racks, terminals and process vents. The scope is built around the actual vapor source and site layout, rather than a fixed catalogue configuration.
Review vapor composition, peak flow, pressure, temperature, liquid carryover and recovery destination before equipment selection.
Supply skid-mounted recovery units with separators, compressors, condensers, adsorption beds, valves, instruments and controls.
Coordinate fabrication, piping, control-panel integration, inspection, packing, shipment and site handover.
Support installation, commissioning, spare-parts matching and operating reviews for overseas projects.
For a project discussion, start with the VRU equipment manufacturer and supply scope page, then review VRU sizing data, the RFQ data sheet and the installation and commissioning scope.
Request a preliminary VRU evaluation
Send the available gas data and operating conditions. PollutionCtrl can compare the two product routes and identify the measurements needed for preliminary sizing.

Vapor Recovery Unit Design for Oil and Gas
PollutionCtrl supplies vapor recovery units for oil and gas storage, tank farms, terminals, truck loading and gasoline vapor control. A vapor recovery unit manufacturer should review tank pressure, vapor composition, flow variation, liquid carryover, compressor duty, recovery target, hazardous-area requirements and the operating pattern before final selection.
VRU system design may combine a compressor package, condensate or liquid separation, controls, piping, valves, instrumentation and recovery or discharge connections. The equipment arrangement should match the tank farm or terminal layout and the customer’s operating and maintenance requirements.

VRU RFQ Information
For a VRU RFQ, provide tank volume, vapor source, peak and normal flow, pressure range, gas composition, temperature, liquid carryover risk, recovery destination, site classification and preferred control interface. This information helps determine the compressor, separator, piping and instrumentation package.
