<p>An apparatus for storing a multi-component cryogenic liquid in which headspace vapor in a storage tank is condensed in an external condensation tank through in direct heat exchange with liquid being vented from the storage tank. The resulting cond ensate can then be re-introduced into the storage tank through a pressure building circ uit applied to the external condensation tank. In such manner, the pressure within t he storage tank is regulated and the composition of the liquid stored within the st orage tank is held with some degree of consistency. The use of an external condensatio n tank allows prior art cryogenic storage tanks and dewars to be retrofitted to store a multicomponent cryogenic liquids.</p> |
