Gasoline vapor recovery
In a gasoline distribution network wherein gasoline is drawn from a gasoline storage tank and pumped into individual vehicles and wherein the gasoline storage tank is refilled periodically from a gasoline tanker truck, a method of recovering liquid gasoline from gasoline vapor that collects in the headspace of the gasoline storage tank as the liquid gasoline is drawn therefrom, said method comprising the steps of: (a) providing a source of inert gas; (b) introducing inert gas into the gasoline storage tank as liquid gasoline is drawn therefrom so that liquid gasoline drawn from the tank is displaced by inert gas and gasoline vapor mixes with the inert gas in the headspace of the tank; (c) collecting the inert gas/gasoline vapor mixture from the headspace of the gasoline storage tank as the tank is refilled from a gasoline tanker truck; (d) cooling the inert gas/gasoline vapor mixture to a temperature sufficient to condense the gasoline vapor in the mixture to liquid gasoline but not sufficient to liquify the inert gas in the mixture; (e) separating the condensed liquid gasoline from the inert gas; and delivering the condensed liquid gasoline to a remote location for subsequent use.
