LNG filling station is a special facility to provide fuel for trucks, LNG buses and LNG ships. The liquefied natural gas transported by LNG tanker or container tanker is pressurized and unloaded into the LNG storage tank in the station by unloading the pressurized vaporizer. When using, low temperature submersible pump LNG pressure, through the filling system to LNG cars, LNG ships and other gas filling. The general composition is: LNG tank, LNG submersible pump, gas dispenser, EAG heater, booster gas, control system, safety system and other auxiliary equipment.

Safety knowledge of LNG filling station

1, LNG has very low temperature at ambient atmospheric pressure: -162;

2, there is a large gas-liquid volume ratio, if the pressure reduction measures inappropriate, will lead to rapid pressure rise. The gas liquid volume ratio of LNG is about 620:1;

3, the early filling amount is small, the natural vaporization back leads to the gas loss rate is too large;

4, LNG vehicles inevitably exist emission problems in the city;

5, natural gas is flammable gas, the production area has obvious safety signs;

6, skid mounted LNG car filling station should be used in complete security measures and fixed point, strictly prohibited mobile use, vacuum process pipeline is not allowed to step on;

7, the transport process is strictly prohibited collision tank, storage tank must maintain vacuum;

8. Maintain good ventilation in the area where the equipment is located;

9. Ensure the system has been released when maintaining or maintaining the equipment;

10. Keep away from flammable or electrical sparks;

11, the electrical part and instrument parts can not enter the water;

12. All electrical equipment should meet the requirements of explosion-proof grade in dangerous area;

13. In the area with LNG, no open flame or any unauthorized electrical and communication equipment, such as mobile phones and radio transmitters, can be used.
