Overview:
The L-CNG fueling system is a device used to convert liquefied natural gas (LNG) into compressed natural gas (CNG) through on-site gasification and then refuel CNG vehicles. The main equipment required for this system includes LNG storage tanks, LNG pumps, vaporizers, gas storage cylinders, and CNG dispensers.
Features:
Pressurizes low-pressure LNG up to high-pressure LNG with a maximum pressure of 25 MPa, with a safety venting function.
Core functions are controlled automatically, reducing human operation errors and enhancing operational safety.
The plunger pump is installed separately from the main skid. On one hand, the pump is directly connected to the foundation to reduce vibration, and on the other hand, it avoids the impact of vibration on skid components.
Considering actual operating conditions, the plunger pump inlet pipeline uses Forlax insulation or vacuum insulation to prevent LNG vaporization from affecting pump inlet performance.
The vacuum pipeline structure of the plunger pump is equipped with an inlet buffer and gas-liquid separator to ensure pump inlet flow and reduce LNG vaporization impact.
The pump return pipeline is designed with upward and inclined angles to facilitate gas return.
The skid body has a compact volume, reducing on-site footprint.
