HIAD Nature Event - Flame Type: Jet flame


Due to the road accident there was the formation of a fire that involved the hydrogen tube trailer and some other vehicles (involved in the incident).Moreover due to the crash there was the formation…
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 incident occurred in a hydrocracker unit of the refinery. A control valve on the liquid line between the high- and the low-pressure separators was opened in error and the liquid allowed to drain…
During functional tests of the system, a major quantity of hydrogen-containing gas was released from an adsorber, followed by its ignition.After the alarm was released the feed of the adsorber was…
A major leak (estimated between 1.5 and 3 kg) of hydrogen from high-pressure storage, resulted in a detonation, from hydrogen a refuelling station.Causes were two untightened bolts securing the…
The event started when a gasket in a water pump was blown out. The water pump was situated inside a 100 m long, 10 m wide, and 7 m high building. The pump was feeding water to a vessel containing…
The release and fire occurred during what appeared to be a normal operation in a reactor section of a Residue Hydrotreater Unit, when an eight-inch pipe connected to a heat exchanger failed at the…
Several explosions occurred in one of the catalytic reforming units of the refinery, followed by a fire in the same unit. The fire derived from the explosions lasted for almost one day. The…
An operator had just replaced the ignition port cover on a hydrochloric acid plant burner. Normal start-up was continued by closing the drain valve in the product run off line and opening the…
Weld failure caused a fire involving a hydrogen pipe at a fertilizer ammonia plant. Source of ignition was autoignition.
Fire broke out along a transition corridor combining several underground pipelines transporting hazardous substances, including hydrogen, kerosene and ethylene oxide. The fire was brought under…
Fire in a ammonia plant.The accident starts with a leak of a hydrogen-nitrogen mixture at the suction flange of a compressor. The mixture ignites on contact with air and the fire spreads to an oil…
Hydrogen and butyl acetate released and caught fire on the vent of a hydrogenation reactor, part of a dyes manufacturing plant. The pressure inside the reactor increased due to excess hydrogen…
The fire occurred in the unit for the production of the hexamethylenediamine (HMD). The process is based on the hydrogenation of the adiponitrile [(CH2)4(CN)2]A jet fire of hydrogen was generated…
A leak occurred on a 4 inch hydrogen main gas line which ran along a pipe bridge at the east end of a first stage compression plant building, ignited.The source of ignition was hot welding sparks…
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…
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 accident originated in the isomerisation unit and propagated to the benzene saturation unit. The accident source was a mechanical rupture of one of the two compressors used to transfer hydrogen…
H2 Tanker Ignites in California - Compressed hydrogen gas inside a tanker truck caught fire sending a hissing flame as high as 60 feet into the air and forcing the evacuation of a one-mile stretch…
A release of compressed hydrogen and subsequent fire occurred during the transportation of truck tractor chassis with a mounted trailer module. The tube trailer module contained 25 fully wrapped…
