ABSTRACT:
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 indirect heat exchange with liquid being vented from the storage tank. The resulting condensate can then be re-introduced into the storage tank through a pressure building circuit applied to the external condensation tank. In such manner, the pressure within the storage tank is regulated and the composition of the liquid stored within the storage tank is held with some degree of consistency. The use of an external condensation tank allows prior art cryogenic storage tanks and dewars to be retrofitted to store a multi-component cryogenic liquids.
