LNG truck filling station mainly consists of LNG tank, LNG storage tank, unloading/pressure regulating supercharger, LNG cryogenic pump, gas filling machine and LNG vehicle system, etc. LNG truck filling station is generally conventional station and skid loading station
The above two kinds of LNG filling stations are basically the same in terms of the main equipment composition, the difference is :LNG filling machine, booster pump pry and other equipment is integrated on the pry body. The skid-mounted LNG filling station equipment has a small amount of on-site construction and a short installation and commissioning period, which is suitable for LNG filling stations with small scale and low site requirements: The fixed LNG filling station has a large amount of on-site construction and a relatively long period, which is suitable for large-scale LNG filling stations.
The process flow of LNG truck filling station is divided into four steps: unloading process, pressure regulation process, gas filling process and pressure relief process
1.The gas filling process refers to the process that the LNG in the LNG storage tank is pressurized by the submersible pump, and then fed by the gas filling machine to the LNG vehicle after measurement. Before filling the car with gas, the car storage cylinder must be decompressed first, and the gas generated in the bottle can be recovered through the return gas pipeline on the filling machine to reduce the pressure of the storage cylinder.| item | name | type | quantity |
