Two.LNG/L-CNG Filling Station Process Flowchart
  1. Unloading Process: Transfer LNG(liquid natural gas) from the tank truck to the LNG storage tank of the gas station through the LNG submersible pump skid(including the unloading truck and the tank booster) at the gas filling station.
  2. Pressurization Process: After unloading, the LNG is pressurized to above 23Mpa by the LNG high pressure pump skid, and then gasified into CNG(high pressure natural gas)by the high pressure vaporizer skid(including high pressure vaporizer, high pressure water bath electric heating reheater, and sequence control panel), and enter the high pressure gas cylinder group for storage.
  3. Gas Filling Process: When the pressure in the high pressure gas cylinder group is too low to be able to refill normally, the high pressure pump restarts and vaporizes to replenish and pressurize the high pressure gas cylinder group, and refill the car.
  4. Liquid Filling Process: LNG is pressurized to about 1.6Mpa by the LNG submersible pump skid, and LNG is filled into the car bottle group through the pipeline and LNG dispenser.
