ABSTRACT:
A method and apparatus for venting volatile organic compound vapors from a liquid storage vessel which includes the steps of introducing a purge medium to a liquid storage vessel containing volatile organic compound vapors and establishing an uniform and continuous stratified interface between the purge medium and the volatile organic compound vapors. The introduction of the purge medium is continued causing the continuous stratified interface to move within the vessel purging the undiluted volatile organic compound vapors from the vessel and into a vapor recovery line which delivers the volatile organic compound vapors to a vapor handling device. Preferably, the purge medium comprises carbon dioxide or nitrogen.
