Vapor recovery is applied wherever gasoline or light hydrocarbon vapors are stored and handled. We size systems for three common facility types.
| Consideration | Typical Approach |
|---|---|
| Vapor source | Underground storage tanks during vehicle refueling and tanker unloading |
| Vapor flow profile | Intermittent, peaks during busy hours |
| Recommended route | Membrane separation (WHSH-M) — automatic start/stop on tank pressure, handles intermittent station loads |
| Footprint | Compact skid that fits existing station yard layouts |
| Typical capacity | 4 – 20 m³/h per unit (WHSH-M series) |
| Installation | At the tank breather valve area; inlet DN50, return DN20; gravity oil return — no raised platform needed |
| Consideration | Typical Approach |
|---|---|
| Vapor source | Storage tank breathing losses, filling operations, manifolded tank systems |
| Vapor flow profile | Continuous with operational peaks |
| Recommended route | Custom-engineered trains — contact us with vapor flow, composition and discharge targets |
| Capacity | Project-specific — sized from your throughput and vapor flow data |
| Controls | PLC with tank level/pressure interlocks, remote monitoring options |
| Integration | Can integrate with existing vapor balance and loading control systems |
| Consideration | Typical Approach |
|---|---|
| Vapor source | Vapors displaced during tank truck bottom/top loading |
| Vapor flow profile | Short high-rate peaks per loading bay |
| Recommended route | Hybrid trains sized to simultaneous loading rates |
| Vapor balance | Vapor return lines from loading arms back to the recovery unit |
| Safety | Explosion-proof area equipment, flame arresters on vapor lines |
| Capacity | Sized per bay count and loading rate — custom engineering |
