HIAD Facility - Application: Fertilizers Production
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…
An explosion and fire occurred on a reformer at a fertiliser plant. Source of ignition was autoignition or electric motor.
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…
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 accident occurred during the maintenance of a sulfuric acid storage tank in an industry for the fertilizers production. The maintenance works consisted in cutting operations (to remove some…
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…
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 /…
In a fertilizer manufacturing plant, a gas leak occurred at an ammonia unit heat exchanger located in a ventilated area outside. The operator partially stopped the unit, set up steam hoses and…
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…
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…
