Safe Process

Safety measures:

lLevel 1: No leakage of hydrogen → safety features of the equipment, involving selection of parts, safety monitoring, hazop/LOPA analysis, and SIL rating

lLevel 2: Real-time detection of any leakage and prevention of further leakage → safety control system design, involving monitoring in the entire plant

lLevel 3: No accumulation of gas in case of any leakage → ventilation engineering design for safety

lLevel 4: Ignition sources eliminated → no-smoking and other safety management principles

lLevel 5: Minimum impacts on the surroundings in case of any fire accident → approval and design of safety facilities such as explosion-proof walls and safety distance

 

Safety features of the equipment

Selection of parts:

316L/carbon steel Ni-coated alkali-resistant material is used for the alkali liquid, and degreased stainless steel used for the oxygen end with a restrictive flow orifice plate to prevent any safety hazard

Explosion-proof classification for electrical units: IIC T4

Valves: 3-piece welded ball valve with less possible leakage points.

Mass flow meters for hydrogen, and electromagnetic flow meters for alkali liquid.

 

Safety monitoring:

To prevent over-temperature and maintain the liquid level balance, pressure regulation, upgraded purity measures, and cell voltage monitoring for the electrolyzer

PLC monitoring and control system, two of three instruments used in the SIS system, and GDS system
