ABSTRACT:
A method and apparatus for venting cryogenic storage tanks. In the method, a non-flammable, non-combustion supporting, relatively warm gas is mixed with cold vapors vented from a cryogenic storage tank to warm the vented vapors to a characteristic density less than that of the air adjacent the tank. The apparatus employed includes a vent pipe having a Venturi ejection throat therein, a pressure relief valve spaced from the ejection throat, and a gas ejector nozzle extending into the vent pipe between the safety relief valve and the ejection throat.
