  • Method of controlling vapor loss from containers of volatile chemicals
    Patent number: 5176002
    Abstract: A substantially closed vapor control system is provided for recovering volatilized vapors released during the filling of storage and other types of tanks with hydrocarbons or other volatile chemicals. An inert gas is supplied to thetank and mixes with the volatilized vapors during loading of the hydrocarbon or chemical to produce an inflammable vapor mixture. The vapor mixture is then subjected to a two-stage compression and separation process to condense and separate the volatilized vapors from the inert gas. The condensed volatilized vapor is then returned to the storage tank while the inert gas is liquefied and stored for subsequent delivery to the storage tank when the hydrocarbon or chemical is unloaded from the tank.
