Process and apparatus for the storage and transportation of liquefied gases

Patent ·
OSTI ID:6916546

A vessel is described which employs a number of cryogenic tanks for the storage of liquefied cases. The cryogenic tanks are provided with conduit means and a heat exchange means whereby the unavoidable boil-off from a lower boiling liquefied gas stored in a first cryogenic tank is passed in indirect heat-transfer relationship with the unavoidable boil-off from a higher boiling liquefied gas stored in a second cryogenic tank to reliquefy the vapors of the higher boiling liquefied gas. Additional conduits are provided to permit alteration of the gaseous atmosphere in the second cryogenic tank (after unloading its content) to the atmosphere of the liquefied gas to be subsequently stored and transported therein.
