Skid-Mounted L-CNG Filling Station

Application

The equipment integrates high-pressure low-temperature plunger pump, high-pressure vaporizer, CNG Gas Cylinder Group, dispenser and control panel into one skid.

In a typical LNG plant the sequence is: Feed gas → Pre-treatment → Liquefaction → Storage → Loading.

Scope of supply

• It, combined with LNG tank, fills vehicle with CNG fuel at the designated areas.
• The main equipment: LNG storage tank, BOG storage tank car, BOG heater, EAG heater, booster vaporizer for tank car, booster vaporizer for storage tank, LNG low-temperature booster pump(immersed pump), dispenser, control system, security system and other assistive devices.
• Characteristics 3D Technical performance: ◆ Gas supply Capacity: 500~5000Nm3/h ◆ Gasification Mode: High-pressure air-heated vaporizer ◆ Reheating Mode: High-pressure electricity, hot-water or steam ◆ Output Pressure: High pressure ◆ Shut-off Valves’ Motive Power: Compressed Air or Nitrogen ◆ Safety Facilities: Fire protection, lightning protection, relief device ◆ Control Mode: Central control and monitoring system Process: a.
• Unloading process: Moving LNG from tank car to LNG storage tank at the Filling Station b.
• Regulating process: LNG will be pressurized to above 20MPa by LNG high-pressure pump, after uploading; then the gas will be vaporized into CNG by high-pressure vaporizer, and go into high-pressure storage well or cylinder group; c.

Capacity, design conditions and scope of supply are confirmed per project.
