    摘要: Station for dispensing natural gas, which comprises a source of natural gas (2) in the form of compressed gas or in the form of cooled liquid, a dispensing column (dispenser) (3) of such natural gas and feed means (4), which are hydraulically connected to the source of natural gas (2) and to the dispenser (3) in order to send the natural gas from the source to the latter. The dispenser (3) comprises at least one suction hood (100), positioned above the ground level, provided with a suction opening (101), susceptible of collecting natural gas dispersed in the environment, and with at least one expulsion opening (102) for evacuating the collected gas safely. The relevant engagement seat (30) of the gas dispensing head (5) is arranged below the suction opening (101) of the hood (100). The latter is exposed to an air flow, forced or natural, which crosses the relevant mechanical and/or electrical components controlling the gas flow to the heads (5), so as to safely evacuate possible leaks thereof.

    摘要: A pressure vessel refueling system enables fast refueling of Compressed Natural Gas (CNG) fuel tanks. The system includes a pressure vessel having a gas inlet/outlet port and a liquid inlet/outlet port; a first liquid at least partially filling the pressure vessel; a liquid layer of a second liquid floating on top of the first liquid, wherein the second liquid is immiscible with the first liquid; a gas at least partially filling the pressure vessel above the liquid layer of the second liquid, the gas in fluid communication with the gas inlet/outlet; and a pump in fluid communication with the liquid inlet/outlet of the pressure vessel, whereby the first liquid can be pumped or returned to/from storage into or out of the pressure vessel.
