LNG & L-CNG Vehicle Refueling Stations | Turnkey Solutions | MINGXIN
 |
Product Overview
MINGXIN’s LNG/L-CNG Filling Station is a highly integrated, cutting-edge refueling solution designed to serve both Liquefied Natural Gas (LNG) heavy-duty trucks and Compressed Natural Gas (CNG) light vehicles from a single cryogenic LNG storage source. By combining the direct dispensing of LNG with the high-pressure vaporization of LNG into CNG, this "two-in-one" station drastically reduces footprint, lowers capital investment, and maximizes operational profitability. It is the ultimate turnkey infrastructure for modern clean energy transportation.
How It Works (The 2-in-1 Solution)
LNG Refueling: Cryogenic LNG is pumped directly from the main storage tank via a submerged pump skid and delivered to heavy-duty trucks through a highly accurate LNG dispenser.
L-CNG Refueling: LNG is pressurized by a high-pressure cryogenic piston pump, converted into gaseous CNG through an ambient air vaporizer, stored in a high-pressure cylinder cascade, and finally dispensed to passenger cars and buses via a CNG dispenser.
Core System Modules
The MINGXIN LNG/L-CNG station is built with a modular, skid-mounted design for rapid on-site deployment. The complete system includes:
Cryogenic Storage System: High-vacuum multi-layer insulated LNG storage tanks (typically 30m³ to 100m³).
LNG Submerged Pump Skid: For unloading trailers and directly dispensing low-pressure LNG to vehicles.
High-Pressure L-CNG Pump Skid: Heavy-duty cryogenic reciprocating pumps to boost LNG pressure up to 25 MPa (250 bar).
High-Pressure Vaporization Skid: Star-fin ambient air vaporizers that efficiently convert high-pressure liquid into CNG with zero energy cost.
CNG Storage Cascade: High-pressure cylinder groups to buffer and store the generated CNG for peak-hour dispensing.
Dispensing Systems: State-of-the-art, mass-flow-meter-equipped LNG and CNG dispensers for precise billing and safe fueling.
Smart PLC Control Room: A centralized, fully automated SCADA control system managing valves, pumps, billing, and safety interlocks.
Key Features & Design Highlights
Highly Modular & Skid-Mounted: Core components are pre-assembled, pre-piped, and pre-wired on steel skids at the MINGXIN factory. This "Plug & Play" design cuts on-site civil works and installation time by over 50%.
Intelligent Automation: The advanced PLC control panel allows for one-touch operation, automatic unloading, automatic pressure building, and seamless switching between standby and active modes.
Uncompromising Safety (ESD): Equipped with a comprehensive Emergency Shutdown (ESD) system, combustible gas detectors, ultraviolet flame detectors, and automatic pneumatic shut-off valves to ensure 100% station safety.
BOG Management System: Smart Boil-Off Gas (BOG) recovery systems capture evaporated gas and repressurize it into the CNG cascade, ensuring zero gas venting and maximum economic return.
Industry Applications
Public Transit & Fleets: Simultaneous refueling for municipal CNG buses, taxis, and LNG heavy-duty logistics trucks.
Highway Service Areas: High-capacity refueling hubs along major transport corridors for long-haul logistics fleets.
Mining & Heavy Industry: On-site refueling stations for large-scale mining dump trucks transitioning from diesel to clean LNG.
City Gas Peak-Shaving: Can be integrated with local city gas pipelines to supplement municipal gas supply during peak winter demand.
