METHOD FOR RECOVERING GASOLINE VAPORS IN FILLING STATIONS AND APPARATUS FOR PERFORMING THE METHOD

摘要

A method for recovering gasoline vapors in filling stations entails extracting the gasoline vapors during fuel delivery and dehumidifying the extracted vapors by passage through a cartridge which contains a dessiccant. The dehumidified vapors are then condensed into a liquid form by heat exchange with an intermediate fluid kept at the cooling temperature in contact with a heat exchanger through which a coolant flows. The liquid condensate is then separated and recovered and the appropriately treated and conditioned residual gaseous mixture is released into the atmosphere.
