Summary
LNG station can be divided into 2 types: skid-mounted LNG station and stationary LNG station. Skid-mounted LNG station is to integrate storage tank, pump skid, PLC control system and LNG dispenser in one skid, which is convenient to transport the full station. Stationary LNG station is to install storage tank, pump skid, PLC control system and LNG dispenser in the station.
Main equipment composition: cryogenic storage tank, LNG cryogenic immersed pump, LNG unloading skid, instrument wind system, PLC control system etc. Main function: LNG unloading, pressure regulating, LNG filling, metering etc. Main advantages: modular design, high integration level, convenient and efficient installation.
Main functions
■Unloading: unload LNG from tank car to storage tank through self-pressurization and pump.
■Refueling: refuel LNG to vehicle cylinder through cryogenic pump and LNG dispenser.
■Saturation regulating: pumping partial LNG to vaporizer from storage tank by LNG cryogenic pump, and return to the bottom of storage tank after vaporization, which increases the temperature of LNG storage tank thereby increase the storage tank pressure.
1 Skid-mounted LNG station
Summary
Skid-mounted LNG station is the complete LNG refueling system which assembled, tested and debugged in factory. This kind of system integrates LNG storage tank, LNG immersed pump, PLC control system and LNG dispenser in the skid, which is convenient to transport the full station. It can finish unloading, pressure regulating and refueling independently. It can be divided into 2 types: skid-mounted LNG station and container LNG station.

2 Stationary LNG station
Summary
Stationary LNG station is the LNG refueling system that is composed of 4 subsystems: LNG storage tank, LNG pump skid, LNG dispenser and PLC control cabinet. Each module finishes assembling, testing and debugging in factory. The station can be put into trial operation after each module connected, installed and debugged simply at site.
