ABSTRACT:
A Stage II Vapor Recovery System is provided with a special array of storage tanks, dispensers, fuel pumps, vapor assist pumps, and flow control nozzles, to capture hydrocarbon emissions, prevent condensate from blocking vapor return lines, and dispense gasoline or other liquid fuel and condensate to customer tanks. Specifically, fuel lines connect storage tank to flow control nozzles via dispensers and are assisted by fuel pumps to pump gasoline into customers' tanks. The nozzles have vapor passageways to capture hydrocarbon vapors emitted during fueling. The captured vapors are pumped by vapor assist pumps from the vapor passageways through vapor return lines into the storage tanks. The nozzles are equipped with condensate liquid pickup tubes to remove condensed vapors blocking the vapor return lines. The condensate liquid tubes communicate with condensate venturi ports adjacent venturi sleeves in the nozzles. Liquid sensing tubes in the vapor return passageways activate automatic shutoff valves in the nozzles to shut off the flow of gasoline when the customer's tank is filled.
