Abstract

A refueling process for cryogenic liquids, in which the cryogenic liquid in question is transferred from a storage tank into a receiving tank via a detachable line connection. Before or during the refueling process, the cryogenic liquid is cooled in the storage tank to a temperature that is below the lowest operating temperature intended in the tank and above the freezing point of the liquid. The cryogenic liquid is transferred into the tank through a filter with a fineness of 5 to 40 .mu.m, and its temperature is increased during the transfer to a value that at least approximately corresponds to the intended operating temperature in the receiving tank.
