A weld on a 1 inch diameter instrument tapping from a Octafiner reactor overhead line fractured, resulting in a small but intense fire, lasting about 50 minutes until the unit was nitrogen purged.The…

A fire on a hydrogen pipeline in a refinery.

A hydrogen leak occurred on a 50 mm pipe feeding a reactor. The leak ignited spontaneously when mixed with air. Thanks to the closing of the input and output valves, the quantity released could be…

A pipe failed, probably due to material failure, and the plant was automatically put in hot stand-by (feed and energy supply automatically cut out). The plant was gradually cooled down. After about…

The incident occurred in the turbine-generator hall of a nuclear power plant. Hydrogen leaked from the alternator and ignited.The hydrogen line was purged to stop the leak. The plant employees were…

Around 4 a.m., a major leak occurred at the outlet of the diesel hydrodesulfurization furnace in a refinery. The goal of this unit is to lower the sulfur content of diesel fuels produced in other…

In a petrochemical plant, a fire occurred on the methanation unit (95% H2 + 5% CO -> CH4 + H2 + H2O) of a steam cracker. A seal break on a flange of the circuit caused of the accident. No…

On April 29, 1991, a nuclear Power Plant experienced a main generator hydrogen fire. Although a senior reactor operator (SRO) and auxiliary operators from another shift were available immediately,…
