HIAD Facility - Application: Ammonia Production

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…

Furnace tube leak caused excessive heat on H2 tube causing rupture

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…

This resulted in the destruction of the building where the explosion occurred and claimed the lives of two people. The triggering event was a blowing out of a gasket in a water pump situated in a 100…

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.

A joint failure allowed a mixture of hydrogen and nitrogen into the atmosphere.Failure of double cone joint on waste heat boiler in synthesis loop caused release of synthesis gas at 28.7 MPa and 170…

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…

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…
