A method and filling station are disclosed for introducing a compressed gas stream into one or more vessels such that upper and lower temperature material limits are not exceeded and preferably such vessels are not over or under filled by controlling the filling temperature of the compressed gas stream. The compressed stream is produced by compressing a stream composed of a vapor phase located within a cryogenic liquid storage tank. The density of the vapor phase is held constant by adding heat to a liquid phase, preferably by addition of a subsidiary stream composed of the compressed gas stream. The filling temperature of the compressed gas stream is controlled by adding heat to the compressed gas stream by a trim heater or to the vapor stream to be compressed by recirculating part of the compressed gas stream to an inlet of the compressor. |
