Search term LEL or Combustible Detectors and are available in market by all leading manufactures. I am using it for my H2 plant for fertilizers but not in refineries.........

You need to install many detectors based on area, local wind direction, construction site etc....... when ever you get alarm in your Operator interface system for any of the detector - gives you near by location for Hydrocarbon or Hydrogen leakage.........
Dear amshah,
We are requested to provide UV flame detectors for any hydrogen risk on site with potential fire location.
We are required to provide only UV flame detectors for the following location as hydrogen leakage detection. It means any hydrogen risk on the site shall have potential fire locations monitored by Ultra-violet flame detectors (not Infra-red units). Target and location of "Hydrogen fire detection" shall be as follows:
- High temperature (above 220 deg C) and high pressure (more than 42 barg)
- Large pipe size (larger than 8 inch flanges).
- The coverage of hydrogen detection shall be max. 30 m.
Could you please share what you have at your site: Hydrogen detectors or UV flame detectors for detect hydrogen (in both case: detect hydrogen gas leakage before fire occurs and also are interested in fire (UV detector).
Please advise your experience. Many thanks
Tan
