The storage tank consists of a main tank and ullage tank connected by a relatively small passage having a flow rate capacity up to 30% of the main fill line. To fill the tank, liquid cryogen is delivered to the main tank by either a top or bottom fill. Because the fill line is significantly larger than the passage, the main tank will become liquid full while the ullage tank remains substantially e...
