Gasoline vapor recovery systems or aspirators are used to capture vaporized product at the balance stage recovery nozzle.

Aspirators use suction to capture vaporized product.  Captured vapors are returned to the source tank. Vapors that escape the aspirator become a lost product.

Aspirator systems are at most fueling stations and fuel depots. Not using an aspirator can be costly to a company.

A good gasoline vapor recovery system can drastically reduce the amount of product a company loses to evaporation.

The state of California was a leader in implementing state legislation to require vapor recovery systems at any facility that dispenses fuel.  California emissions rules are considered to be some of the toughest in the United States.

Evaporation of product starts right after refinement as the finished product sits in large storage tanks.  After that evaporation of the product continues at…

  • When the gasoline is transferred to a tanker to go to a commercial fuel depot.
  • When the gasoline is being transferred by the pump to the fuel depot.
  • When the gasoline is picked up at the central depot to be distributed to gasoline stations.
  • When the gasoline is being pumped into the tanks at the gasoline station.
  • When the gasoline is being pumped into a consumer’s car.
  • As the gas sits in the tank of a consumer’s car.

You can begin to understand that gasoline is something of a wasting asset as it begins to naturally disappear from the minute it is manufactured.  The measures put in place to recover the evaporated product are good for both the environment and the bottom line.
