Abstract: Method for determining the initial pressure of a pressurized gas tank to be filled from a dispensing station, the dispensing station comprising a filling line including in series a pressurized gas source, a heat exchanger, and a dispenser, the dispensing station also comprising a bypass line on the filling line around the heat exchanger, the method comprising the following steps: a step of transferring a gas flow from the gas source or the heat exchanger to the dispenser via the bypass line, a step of reading an initial pressure in the tank to be filled as a function of a pressure measured on the filling line.

Abstract: Method for preventing or limiting icing of a station for distributing a pressurized gas, the station comprising a filling line having in series an end connected to a source of pressurized gas, a first heat exchanger for cooling a gas flow coming from the source, and a distribution terminal intended to distribute the cooled flow to a reservoir to be filled, the distribution station also comprising a bypass line of the filling line at the first heat exchanger, the method comprising a step of transferring a flow of relatively hot gas to the distribution terminal via the bypass line, the flow of relatively hot gas being at a temperature higher than a predefined temperature at the outlet of the first heat exchanger.

Abstract: Device and method for filling pressurized gas tanks, comprising a pressurized gas source, a transfer pipe connected to a tank to be filled, the transfer pipe comprising a set of valve(s) and a compressor, the device comprising a sensor for detecting the presence of oil in the gas flowing in the transfer pipe downstream of the compressor, the device comprising a bypass pipe connected to the transfer pipe downstream of the compressor and comprising a set of at least two valve(s) in series which are configured to enable, in a first configuration, the gas flowing in the transfer pipe to be extracted in the bypass pipe and, in a second configuration, fluid isolation between the bypass pipe and the transfer pipe, wherein the valve assembly of the transfer pipe defines in the second configuration a closed storage space for the gas extracted and enclosed in the bypass pipe, the closed storage space comprising a pressure relief system for the gas extracted and enclosed in the bypass pipe for lowering the pressure of t
