ABSTRACT:
In the dispensing of gasoline into a tank used for the storage or transportation of gasoline wherein the gasoline displaces a gaseous mixture of air and gasoline, and said mixture is treated to a recovery step to separate said gasoline from said mixture, there is provided an improvement in the recovery step which comprises cooling said mixture to condense out the gasoline and water from the air thereby purifying the air, and then separating the water from the gasoline. One or two main heat exchangers can be employed depending on whether the system is operated continuously or not. A short regeneration time is made possible by the use of steam which expands the heat exchange tubes sufficiently to remove ice cleanly. An absorber using activated carbon is optionally employed in addition to the removal of the gasoline by cooling.
