HIAD Specific Application Supply Chain Stage: Hydrogen As Feedstock
A deflagration occurred during shutdown of a reactor used for ammonia synthesis. It was followed by a jet fire. The hydrogen leak was probably due first to the lower seals, followed by another leak…
The explosion occurred while restarting the ammonia reactor. Synthetic gas (70% H2) was released at the flange of the relief valve of the turbo-compressor. The explosion was followed by a jet fire.…
The explosion occurred in the compressors unit of the plant. Witnesses reported a cloud of yellow smoke and a fire ball at its bottom. This first event has been followed by a fire fed by a hydrogen…
The syngas leak (hydrogen + methane) occurred at exit of the ammonia production reactor and led to an explosion followed by a fire.The start point of the sequence of events was the syngas at the…
The explosion was followed by a fire. Eyewitnesses reported seeing a "huge gush of fire". The local fire and rescue team brought the fire under control.According to the company, the explosion was…
An explosion occurred caused by a leak of hydrogen from a reactor on a fertilizer plant. The blast hurled the head of a hydrogen gas converter 150m and sent it crashing through reinforced-concrete…
The vent occurred in the ammonia production unit. A minor leak had been detected in a flange on the piping of the ammonia synthesis loop (operating at 250 bar). The company called a specialized…
A gas release occurred in the building for the recirculation of processes gas. The gas was a mixture of hydrogen and nitrogen. It occurred at the outlet valve, during works aiming to replace it. This…
The explosion occurred in the ammonia/hydrogen separator of the ammonia reactor due to metallurgical problem.
A mechanical failure occurred in a gasification reactor, which caused a violent (abrupt, sudden) depressurization of the reactor. The consequences were the projection of tiles of the refractory…
The event occurred during welding works which ignited accidentally released hydrogen. The plant had been partially shut down for repairing works to a pipe affected by internal cracks. The repairing…
In this plant, after conversion of the major part of the carbon dioxide into urea, the off-gasses from the reactor consist of ammonia, carbon dioxide, hydrogen, oxygen and nitrogen. Prior to venting…
The loss of control of a reaction caused a fire in a pharmaceutical plant caused a reaction runaway and the rupture of a 6 m reactor. A cloud containing sodium borohydride and hydrogen was emitted.…
An explosion occurred in a pipe system carrying hydrogen and methane at an ammonia plant. No major injuries have been reported.
The explosion, accompanied by abundant black smoke, occurred at 8:50. An ignited leak of hydrogen (H2) in the ammonia production unit (NH3) had spread to the pressure circuit carrying synthesis gas (…
The failure of a high pressure hydrogen-based synthetic gas feed line to the ammonia converter produced a sudden explosion followed by a severe fire. One of the operators was fatally injured. The…
The cracking happened in an ammonia plant, started up in 1970, on the pipe leading hot synthesis gas from the synthesis convertor to the first heat exchanger. This pipe was affected by six cracks and…
Hydrogen leakage occurred on a pipe flange in an ammonia synthesis unit. A fire started immediately, which was taken under a control before the arrival of firefighters.
the fire was detected by an employee during the normal inspection tour, . It was caused by the ignition of a leak of process gas (hydrogen, methane and water vapour) from the reforming furnaces.…
a gas leakage (approximately 70% hydrogen, 21% nitrogen and the rest carbon monoxide and other impurities) occurred at the connection between a temperature measurement casing and a flange in the…
