L-CNG Vehicle Refueling Skid Process

The L-CNG Vehicle Refueling Skid is a dedicated solution for NGV (Natural Gas Vehicle) refueling, integrating LNG storage, pressure boosting, regasification, and high-pressure CNG filling functions. It is designed for gas stations, logistics parks, and public transportation hubs, enabling efficient and fast refueling for LNG and CNG vehicles.
Core Design Advantages :
Dual-purpose Adaptability : Converts LNG to high-pressure CNG to meet refueling needs of both LNG and CNG vehicles, maximizing equipment utilization.
Intelligent Unloading System : Equipped with an Unloading PBU Skid that automatically boosts pressure and maintains stable pressure during LNG tanker unloading. This ensures a consistent pressure difference between the tanker and the storage tank, avoiding delays caused by pressure fluctuations.
High-Flow Optimization : When the gas flow rate exceeds 2000Nm³/h, the LNG vaporizer can be installed as a separate skid or on an on-site foundation. This design prevents overheating and performance degradation of the vaporizer, ensuring continuous refueling during peak hours.
Additionally, the skid is equipped with an explosion-proof electric heater control box, which enhances operational safety in hazardous environments and meets strict industrial explosion-proof standards.

a) Khối bồn chứa LNG: dùng để lưu trữ LNG và cung cấp chất lỏng, thường được người sử dụng mua hoặc tự trang bị trực tiếp. (Bồn chứa ngang đi kèm với hệ thống áp lực, trong khi bồn chứa dọc áp lực không được trang bị sẵn)
b) Xả hàng từ khung PBU: nhằm tăng áp và duy trì áp suất ổn định trong quá trình tàu chở LNG xả hàng, từ đó các bể chứa LNG có thể đạt được chênh lệch áp suất chất lỏng bình thường, nhờ đó các tàu chở LNG có thể tiếp tục nạp hàng.
c) When the flow rate≥2000Nm³/h, it is recommended LNG vaporizer prized separately or foundational separately on-site.

LNG Storage Tank Skid :
Horizontal tank: Integrated with a pressurization system for autonomous pressure management.
Vertical tank: Does not include a skid-mounted pressurization system, suitable for sites with limited horizontal space.
Vaporizer : 2 sets (optional), with a gasification capacity of 100~3000Nm³/H, ensuring sufficient CNG supply for multiple refueling nozzles.
Pressure Regulator : Inlet-type design, available in single-channel or double-channel configurations. The double-channel option supports alternate operation and maintenance without interrupting refueling services.
Odorization Device : Optional self-priming pump or metering pump, adding odorants (such as mercaptan) to CNG to comply with safety regulations for leak detection.
Metering System : Optional turbine flowmeter or Roots flowmeter, providing accurate fuel measurement for billing and inventory management.
Safety & Monitoring : Optional remote monitoring system and emergency cut-off device. The emergency cut-off function triggers automatically in case of abnormal pressure or gas leaks, minimizing safety risks.

Ghi chú: Trạm hóa hơi khí tự nhiên hóa lỏng (LNG) kiểu mô-đun có thể được tùy chỉnh theo yêu cầu của từng khách hàng.

Packaging :
Skid-mounted main units: Fixed with high-strength steel brackets and anti-vibration pads to prevent structural damage during transit.
Precision components (e.g., pressure regulators, flowmeters): Packed in foam-lined, waterproof boxes to protect against moisture and impact.
Explosion-proof electric heater control boxes: Sealed with dust-proof and moisture-proof covers to ensure internal components remain intact.
Shipping Methods :
Standard Container Shipping: Uses 20GP, 40GP, or 40HQ containers for standard skid sizes, facilitating efficient sea or land transportation.
Bulk Shipping: For oversized or customized skids, bulk vessels or flatbed trucks are used, with additional reinforcement to secure the skid during long-distance transport.
Logistics Support: Our team provides detailed shipping documents (including packing lists, certificates of origin, and customs clearance papers) and coordinates with local partners for on-site delivery and unloading.
