The Skid Mounted LNG Refueling Station integrates LNG storage, cryogenic pumping, metering, dispensing, piping, valves, instrumentation and control systems on a compact skid. It is designed for LNG vehicle fueling stations, fleet depots and distributed energy applications where fast installation, controlled site work and modular expansion are required.

Typical System Configuration

A standard Skid Mounted LNG Refueling Station may include:

LNG storage tank
Cryogenic LNG pump
LNG dispenser
Mass flow meter
Vacuum-insulated cryogenic piping

Cryogenic valves and check valves
Pressure control and regulating devices
Safety relief devices
PLC control cabinet
HMI operating interface

Emergency shutdown system
Gas detection and alarm system, where required
Electrical and instrumentation components
Skid frame and protective enclosure

The final configuration is determined by storage capacity, fueling demand, vehicle type, site conditions and applicable regulations.

How the LNG Refueling Station Works

LNG is transferred from the storage tank to the cryogenic pump through insulated piping. The pump raises the LNG pressure to the required fueling level and delivers it to the dispenser. The dispenser measures the LNG quantity during fueling and transfers it to the vehicle through a cryogenic filling hose and coupling.
The PLC control system monitors key operating parameters such as pressure, pump status, valve position and system alarms. Emergency shutdown functions can stop the relevant equipment and isolate the LNG flow when an abnormal condition is detected.

Testing & Factory Acceptance

Before shipment, the station can be inspected according to the agreed technical specification and inspection plan.
Typical FAT items may include:

Equipment and component inspection
Piping and valve installation inspection
Pressure and leakage testing where applicable
Electrical wiring inspection
PLC and HMI functional testing
Alarm and interlock verification
Emergency shutdown testing
Metering system verification
Overall skid dimensional inspection

Specific FAT procedures and acceptance criteria should be agreed before production for project-based orders.

FAQ

Q: What routine maintenance does the LNG refueling station require?

A: Routine maintenance typically includes inspection of valves, hoses, cryogenic piping, pump components, meters and electrical connections. Maintenance intervals should be established according to operating hours, component manufacturer recommendations and site conditions.

Q: Are spare parts available for long-term operation?

A: Yes. Common replacement parts such as seals, gaskets, valve components, hose assemblies and instrumentation parts can be supplied according to the station configuration. A recommended spare parts list can also be provided for project planning.

Q: What precautions are required when handling LNG during operation?

A: Operators should use appropriate cryogenic PPE and follow site-specific operating procedures when connecting or disconnecting the fueling hose. Personnel should also maintain the required exclusion zones and avoid direct contact with uninsulated cryogenic components.

Q: What information is required for an LNG station quotation?

A: Useful project information includes required LNG storage capacity, expected daily or hourly fueling volume, vehicle types, required fueling flow rate, local power supply, installation location, preferred dispenser configuration and applicable certification or regulatory requirements.

Q: Can you provide technical documentation for EPC projects?

A: Yes. Technical documentation can be prepared according to the project scope, including drawings, datasheets, manuals, inspection records and other agreed documents.

Q: What is the warranty period?

A: The standard warranty period is 12 months, excluding quick-wear parts, subject to the agreed contract terms.

Q: How is the LNG station packaged for export?

A: The equipment is supplied in standard export packaging or customized packaging based on skid dimensions, weight, transportation method and destination handling requirements.

Q: What support is available for overseas installation?

A: Installation and commissioning support can be discussed according to project scope. Site requirements, connection interfaces and commissioning responsibilities should be defined before shipment.
