LNG/L-CNG station control system

The control system for LNG/L-CNG station is consisted of PLG control system, instrument pneumatic system, gas alarming system, flame detection system and safety pressure release system. Main equipment includes PLC control panel, industrial personal computer, display, gas alarm, gas sensor, flame detector, pressure & temperature transmitter, liquid level sensor and explosion-proof solenoid valve.

Product advantages:

1. More safety: When there is abnormal pressure rise or pipeline leakage during loading and unloading, the system automatically closes the relevant pipeline valve, and can automatically cut off power in case of emergency.

2. More economical: less land space, easy to move and transfer.

3. More intelligent: The PLC control system will monitor and control the equipment pressure, temperature and flow in real time, and automatically judge and repair all abnormal conditions to reduce the workload of the operators.

4. More reliable: After the on-site installation of the gas filling equipment, the operation failure rate is greatly reduced, and the construction quality and cold preservation effect of the LNG process pipeline are further improved.
