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.
L-CNG vehicle refueling skid process
a) LNG storage tank skid: for LNG storage and the fluid supply, generally purchased or provided directly by the user. (Horizontal tank comes with pressurized systems, pressurized vertical storage tank deprovision pry)
b) 卸载PBU滑轨：在液化天然气（LNG）运输船卸载液化天然气时，通过增压和维持恒定压力，使LNG储罐达到正常的液位压差，从而使LNG运输船能够进行灌注装载。.
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.

备注：液化天然气（LNG）模块化再气化站可根据客户要求进行定制。.

包装：
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.
配送方式：
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.
