L-CNG Pump Skid

Product Overview

The L-CNG Pump Skid is a compact and integrated system designed to convert liquefied natural gas (LNG) into high-pressure compressed natural gas (CNG). It combines a cryogenic high-pressure pump and gas vaporization unit on a skid-mounted structure, and is widely used in L-CNG refueling stations to supply CNG for vehicles directly from LNG storage.

Working Principle

LNG is withdrawn from the LNG storage tank and pressurized by a cryogenic high-pressure pump while still in liquid phase.

The pressurized LNG then passes through a vaporizer, where it is heated and converted into high-pressure gaseous CNG.

The produced CNG is delivered to CNG storage cylinders or directly to CNG dispensers for vehicle refueling.

Key Features

• High efficiency: Liquid-phase pumping requires significantly less energy than gas compression

• Integrated design: Pump, vaporizer, valves, instruments, and control system mounted on one skid

• Compact footprint: Ideal for space-limited L-CNG refueling stations

• Stable output pressure: Suitable for CNG vehicle refueling requirements

• High safety level: Cryogenic-rated components, pressure protection, and interlock controls

• Flexible configuration: Compatible with different LNG tank sizes and station capacities
