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-laden air to a bed of adsorbent for gasoline and, when the adsorbent approaches saturation, subjecting it to backwashing with air, preferably heated, from a blower to an extent and for a time adequate to remove enough gasoline from the adsorbent to restore it to a regenerated condition, and combusting the gasoline removed from the adsorbent bed in an internal combustion engine. It is also disclosed to drive the blower with the internal combustion engine and to utilize waste heat from the engine to heat the air by passing it through a radiator associated with the internal combustion engine.
