Abstract (en)

[origin: WO2006082122A1] In order to be able to achieve high pressures, pressure vessels are filled according to the principle of "cold filling", i.e. the filler gas is filled into the pressure vessel in a cold state. Once the pressure vessel is filled and the gas is heated to ambient pressure, the pressure in the pressure vessels multiplies several times. A problem that often occurs is that during filling the filler gas or a component of the filler gas mixture freezes out, thereby resulting in a malfunction of the filling device. For this purpose, the filler gas is transported to the pressure vessel to be charged in a cold yet gaseous state. The filler gas is supplied to a heat exchanger in a liquefied state and is then evaporated. The evaporated filler gas or the gas component are returned to the heat exchanger, where it thermally contacts the still liquid filler gas and is cooled to at least approximately the temperature of the liquid filler gas. The gas treated in this manner is very cold but at the same time available in a gaseous state of matter.
