Title
(EN) DEVICE FOR GENERATING GAS IN GASEOUS FORM FROM LIQUEFIED GAS
(FR) DISPOSITIF DE GENERATION DE GAZ SOUS FORME GAZEUSE A PARTIR DE GAZ LIQUEFIE
Abstract
(EN)
The invention relates to a device (10) for generating gas in gaseous form from liquefied gas, comprising: - a first heat exchanger (24) having a first cooling circuit (24a) comprising a liquefied gas inlet connected to a first pipe (18) which is intended for connection to a liquefied gas outlet of at least one liquefied gas storage tank (14), - vaporization means (19) by negative pressure, fitted to said first pipe, and - at least one compressor (26, 28), characterized in that it further comprises a heater (25) having an inlet for gas that is at least partially in liquid form, which inlet is connected to an outlet of the first circuit (24a), and an outlet for gas that is only in gaseous form, which outlet is connected to the at least one compressor (26, 28).
