The main equipment of an LNG refueling station includes: LNG storage tanks, cryogenic hydrocarbon pumps, high-pressure ambient air vaporizers, high-pressure water bath vaporizers, sequence control panels, gas storage wells or cylinder banks, and refueling machines.
LNG Storage Tanks: Used to store liquefied natural gas, these are one of the core pieces of equipment in a refueling station.
Cryogenic Hydrocarbon Pumps: Responsible for drawing LNG from the storage tanks and pressurizing it for delivery to the vaporizers.
High-Pressure Ambient Air Vaporizers: Utilize the natural convection of ambient air to heat the LNG, vaporizing it into natural gas.
High-Pressure Water Bath Vaporizers: Rapidly vaporize LNG using a water bath heating method. When the ambient temperature is low or the vaporization volume is large, high-pressure water bath vaporizers are typically used as auxiliary or backup vaporization equipment.
Sequence Control Panels: Used to control the operating sequence and logical relationships of various equipment within the refueling station, ensuring the safety and efficiency of the refueling process.
Gas Storage Wells or Cylinder Banks: Used to store the vaporized natural gas, ensuring a stable supply during refueling.
LNG refueling machine: This is the interface device between the LNG refueling station and the user's vehicle, used to refuel the user's vehicle with gasified natural gas into the vehicle's gas cylinder.
