IR400 Combustible Gas Detector is Performance-Verified for Ethylene Detection

IR400 Combustible Gas Detector Is Performance-Verified For Ethylene DetectionOur IR400 Combustible Gas Detector now sets a new industry standard as the first combustible point infrared (IR) ethylene monitor to achieve dual FM and CSA performance verification, meeting FM 6310, FM 6320, and CSA C22.2 No. 152 requirements. With a precision IR point sensing element, the Model IR400 Point IR Combustible Gas Detector reliably protects people, equipment, and facilities against the hazards of ethylene gas vapors.

Ethylene is one of the most widely produced organic chemical†worldwide and a major building block for the production of polymers and other materials. It has thousands of applications, with diverse industrial uses ranging from plastic, textile, and detergent production to its properties as a fruit ripening agent. Ethylene is combustible over a wide concentration range and an asphyxiant, requiring high-accuracy monitoring in order to protect workers and plants.

Ethylene production is a highly complex multi-part process. Feed stock can come from multiple sources, including ethane, propane, butane, naphtha, gas oils, or hydrocracked vacuum gas oils. In general, the first step involves steam cracking to separate hydrogen and methane components, which is followed by the recovery of other components including ethane, acetylene, butane, and propane. A final cryogenic phase at the end of the process results in ethylene recovery.

The ethylene production process is energy intensive, and the components are combustible and toxic. Some of the recovered components are reused within the production plant to provide energy. Production of ethylene requires the use of multiple furnaces, compressors, tanks, piping, and valves. The production system and equipment offer multiple sources for potential combustible and toxic gas leaks that require continuous safety hazard monitoring. The potential for explosion and fire is great as well as for worker asphyxiation.

Worker exposure to ethylene occurs in a variety of industrial plants and commercial settings. According to US OSHA, typical worker exposure occurs through: inhalation, ingestion, skin and/or eye contact. The symptoms of exposure to ethylene include irritation to eyes, skin, nose, throat; nausea, vomiting, abdominal pain, lassitude (weakness, exhaustion); dizziness, stupor, convulsions, central nervous system depression; and skin sensitization. Immediate first aid and medical attention are required after exposure.

The low maintenance IR400 continuously monitors for ethylene in the lower explosive limit (LEL) range and provides a 4 to 20 mA analog signal proportional to the 0 to 100 percent LEL concentration. The IR400 features a true fail-to-safe design for dependable gas detection performance. Its heated optics eliminates condensation and a dirty optics indicator informs end users about contaminated lenses, providing the possibility to take corrective action before detection is impaired.. Additionally, the detector requires no routine calibration, a feature that reduces demand for field technician time. These advanced features help prevent unplanned plant shutdowns and improve operational efficiency.
