Storage vessel for liquid air

摘要

Storage of liquid air under conventional conditions in a pressure vessel, which, as usual, has a gas section above the liquid surface. In order to compensate for heat passing through the insulation, liquid is drawn off and passed through a heat exchanger, in which it evaporates. The heat exchanger is in the gas section so that some of the gas there condenses. The air leaving the heat exchanger is then passed to atmosphere. The equipment required for this method is also claimed.
