Refinery ethylene alarm - SKA/NE-301(C2H4)

Refinery ethylene alarm

Ethylene (C₂H₄) It is a flammable and explosive combustible gas, slightly lighter than air in density, and widely used in petrochemical, polyethylene synthesis, plastics, chemical fiber, rubber, and other industries. In production facilities, storage tank areas, transmission pipelines, gas cylinder rooms, and other locations, once leakage occurs, the gas easily accumulates, and when exposed to open flames or static electricity, it can cause major safety accidents such as fire and explosion. EthyleneC₂H₄The alarm is a specialized safety device used in industrial sites for real-time monitoring of ethylene concentration and prevention of leakage explosions.

The entire system generally consists of two parts: an ethylene gas detector and an alarm controller, divided into fixed online monitoring models and portable inspection models.

Fixed ethylene detector: installed at points prone to gas leakage, equipped with a catalytic combustion sensor,24 24-hour uninterrupted collection of on-site ethylene concentration. When the concentration reaches the preset alarm threshold, the detector outputs audible and visual alarm signals, through RS485/4-20mA The signal uploads data to the alarm host,PLC、DCS Or IoT platform, linking exhaust fans and emergency shut-off valves to quickly handle leakage risks. The detector adopts a flameproof explosion-proof enclosure,IP65 Protection, adapting to complex working conditions such as chemical workshops and storage tank docks.

Portable ethylene detector: for inspection personnel to carry, with built-in rechargeable battery, and built-in audible and visual + Vibration alarm, convenient for on-site inspection and leak detection, suitable for equipment maintenance and confined space detection.
