Filling Stations Equipped With Gasoline Vapor Recovery System

To collect toxic emissions, the first stage of a plan to recover gasoline vapor has been completed in all (3,400) filling stations across the country, head of the National Iranian Oil Products Distribution Company (NIOPDC) said.
“Stage I gasoline vapor recovery systems capture vapors expelled from underground storage tanks at gas stations when being refilled by tankers,” Keramat Veiskarami was quoted as saying by the Oil Ministry news portal.
Equipment for stage I vapor recovery includes fittings for gasoline storage tanks to accommodate vapor recovery hoses from the tank truck and pressure vacuum vent valves to minimize the loss of vapor from the storage tank vents.
Gasoline vapor recovery systems are implemented under two stages, he said.
