ABSTRACT:
In the process, fuel is pumped from a storage tank through a dispenser and nozzle into a customer's tank. Hydrocarbon vapors emitted during fueling are collected through a vapor recovery passageway between the inner and outer spouts of the nozzle and conveyed by a vapor pump through vapor return lines into the storage tank. A portion of the vapors in the vapor return lines condense and are removed with the nozzle's condensate pickup tube. The removed condensate is dispensed into the customer's tank.
