Abstract
A system is disclosed for preventing gasoline vapors contained in air vented from gasoline storage tanks from entering the atmosphere, which includes a conduit to pass gasoline vapor-laden air to a bed of adsorbent for gasoline and, when the adsorbent approaches saturation, subjecting it to back-flushing, with or without heat, to an extent and for a time adequate to remove enough gasoline from the adsorbent to restore it to a regenerated condition, and incinerating the gasoline removed from the adsorbent bed.
