Products Description
LNG bunkering stations are dedicated facilities that provide LNG fuel to trucks, LNG buses, LNG vessels, and other modes of transport.
LNG delivered by LNG tankers or container tank trucks is pressurized via an unloading booster vaporizer and unloaded into the on-site LNG storage tank for storage. During operation, a cryogenic submersible pump pressurizes the LNG and dispenses it through the fueling system to LNG vehicles, LNG vessels, and other recipients. A typical station consists of: LNG storage tank, LNG submersible pump, dispenser, EAG heater, booster vaporizer, control system, safety system, and other auxiliary equipment.
Functional Modes
Fueling Mode: LNG stored in the tank is drawn out and pressurized by the LNG cryogenic pump, then dispensed to vehicles through the LNG dispenser.
Unloading Mode: The cryogenic pump transfers LNG from the delivery tanker into the LNG storage tank.
Pressurization Mode: A portion of LNG from the tank is routed through a vaporizer, where it is gasified into BOG (Boil-Off Gas), and then fed back into the tank. The process stops when the tank pressure reaches the preset level.
Temperature Regulation Mode: The LNG cryogenic pump draws a portion of LNG from the tank and injects it into a temperature-raising vaporizer (heater), after which it returns to the tank. The process stops when the LNG temperature reaches the preset value.
A typical pure LNG bunkering station consists of: LNG storage tank, pump skid with submersible pump, tank pressurization vaporizer, unloading vaporizer, EAG heater (these three vaporizers may vary depending on the process configuration), LNG dispenser, and other components.
LNG Bunkering Station Safety Essentials
1. LNG exists at an extremely low temperature of –162°C under ambient atmospheric pressure.
2. LNG has a very high gas-to-liquid volume ratio. If pressure relief measures are inadequate, pressure will rise rapidly. The gas-to-liquid volume ratio of LNG is approximately 620:1.
3. When initial bunkering volumes are small, natural vaporization will result in a relatively high rate of gas loss (boil-off loss).
4. LNG-powered vehicles operating within urban areas inevitably face venting/discharge issues.
5. Natural gas is a flammable gas; clearly visible safety signage shall be posted in all production areas.
6. Skid-mounted LNG vehicle bunkering stations shall only be operated at fixed locations with comprehensive safety measures in place.
7. Unauthorized relocation is strictly prohibited. Vacuum process piping shall not be stepped on or walked over.
8. During transportation, the storage tank must be protected from collision at all times, and tank vacuum integrity must be maintained.
9. Maintain adequate ventilation in all areas where equipment is located.
10. When repairing or servicing equipment, ensure the system has been fully depressurized.
11. Keep away from combustible materials or electrical sparks.
12. Electrical and instrumentation components must not be exposed to water.
13. All electrical equipment shall comply with the explosion-proof rating requirements for hazardous areas.
14. Within any area where LNG is present, open flames or any unauthorized electrical or communication devices, such as mobile phones and two-way radio transmitters, are strictly prohibited.
