I wanted information on petrol.

I wanted information on petrol. I believe that when we store petrol in a proper gas station, a daily rate of 4-5 litres evaporates every 24 hours. If it does, are there any measures to control the evaporation to the minimum.

Thank you and regards,

Answer

Gasoline stations here in Finland have collecting system for gasoline fumes. It´s called “Phase 1 collecting system”.
The system collects evaporated gasoline released to the tank during refill or storage in gaseous form from the special build air-vents of the tank. The fumes will be collected back to the empty gas truck, and transported back to oil refinery for re-liqufication.

The “Phase 2 collecting system” is build in gasoline automats / meters. It collects gasoline evaporated during huffing gas.
