HIAD Specific Application Supply Chain Stage: Hydrogen As Feedstock
The accident took place in a tank-type pressurised separator on the synthesis gas line of an ammonia production plant. The pressurised separator operates at nominal values of 25 bar and 5C. It…
In a fertiliser plant, an ammonia synthesis unit stopped following the malfunction of an alternator (due to a thunderstorm). The safety features were operating normally, yet the synthesis gas (N2 /…
Fire in an ammonia plantA fire broke out in the hydrogen section of ammonia plant.
A fire started on the primary hydrogenation reactor of a chemical plant synthesizing alcohols and acids by reactions between olefins and a H2 / CO gas mixtures. The alcohols are synthesised in 3…
The event occurred on vent stack of an ammonia synthesis unit. The release of the gas was more specifically on the water purge line or the hydraulic guard of the vet stack. The process gas…
In a chemical plant, a fire broke out on a hydrogen column of an ammonia manufacturing unit. The internal security service extinguishes the fire with powder and nitrogen injection. The unit was…
The event took place in the on one out of the seven reactors for ammonia synthesis. The day of the accident, preparation works for the decennial pneumatic test (previous pneumatic test was carried…
Failure of a strainer allowed sand from brine filters to get into mercury cells in a chlorine plant. It appears that the sand obstructed flow and caused excessive hydrogen generation. An explosion…
A release of a mixture of hydrogen, nitrogen and ammonia ignited and exploded in the ammonia synthesis unit. The release occurred on a flange of the heat exchanger. and was due to a crack on the…
A jet fire occurred on the ammonia production unit, caused by a leak on a hydrogen pipe. No victims.
A hydrogen leakage occurred in the ammonia workshop of a plant manufacturing nitrogen products and fertilizer (classified SEVESO high threshold). It was detected by an operator in charge of safety…
A number of minor explosions occurred in the interrupter pot on a chlorine cell. No injuries or damage were reported.No previous explosion shad occurred which was taken to indicate that hydrogen…
In a chemical plant , a process gas leak (4% ammonia and 88% hydrogen) occurs during a purge operation. The cloud of gas ignites and explodes. An employee is killed.
In an ammonia production unit, a 350-bar leakage of synthesis gas (ammonia + hydrogen) occurred in the compressor room. The leak was the result of the failure of a weld on a line (2") at the outlet…
In a fertilizer manufacturing plant, during his inspection round, an operator detected a hydrogen leak at a flange of an exchanger located between the conversion and decarbonisation stages of the…
There was a small leak of syngas (a mixture mainly consisting of hydrogen and carbon monoxide) resulting in a localized fire at a bolted flange joint on the outlet carbon steel pipework of the High…
The leak occurred at the ammonia reactor after a technical shutdown of 4 days. When the production was resumed and the syngas compressor restarted 14 hours later, a jet-fire occurred. The Internal…
Following a trip caused by the safeguarding of an ammonia production line, the syngas released into the atmosphere and ignited.
The event occurred while re-starting the ammonia production unit after a technical stop, a synthesis gas (50% hydrogen, 17% ammonia, methane and nitrogen) leak ignited on a flange located just after…
