A fire broke out following a hydrogen leak on the cyclododecane unit in a chemical plant. A plume of smoke became visible outside the site. The fire was brought under control by putttng the unit in…

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 jet flame occurred in a diesel distillation unit. It was caused by the release and ignition of hydrogen from the low-pressure (60 bar) section of a the unit. It occurred during maintenance works…

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…

A tube in a hydrorefiner heater ruptured resulting in an extensive fire inside and outside the furnace. The main fire in the furnace was extinguished within 15 minutes and the escaping gas / vapour…

The accident occurred in a plant producing synthesized active ingredients for the pharmaceutical industry. An explosion and a fire occurred in one of the workshops of the plant. The chemical reaction…

The hydrogen release of a defect valve ignited due to an unknown cause. The fire caused the melting of soldered joint with consequence additional release of hydrogen at 6.2 bar, which contributed the…

Fire on a filter of an autoclave. The event occurred in a plant for the production of plastics. After catalytic synthesis of amines, the filter of the autoclave was taken out for cleaning. During…

The event occurred in an alkylation reactor. Due to the rupture of a pipe (probably due to material failure), a power failure took place and the plant was automatically put in hot-stand-by mode. This…

Follow a leak in a seal of a heat exchanger (metal-covered asbestos) a fire occurred in a reforming process. The hydrogen-rich mixture caused spontaneous inflammation. The fire lasted 30 minutes. The…

Due to the failure of a exhaust system, compressed hydrogen leaked into an area containing electrical components, with consequent fire.Leakage was allowed when exhaust system failed

The fire was in a polyamide production chemical plant classified SEVESODuring maintenance of an isolated unit producing a polyamide monomer (LACTAME), a fire developed on the ground floor of the unit…

A fire broke out at a flange of a heat exchanger used in the catalytic reforming unit of a refinery. This exchanger makes it possible to heat the load of heavy oil and hydrogen by recovering the heat…

A fire occurred at an oil factory during maintenance work. On the day of the incident, a distillation unit was shutdown for a steam air tightness test. Cooling equipment on the distillation unit was…

The accident occurred in the de-sulfurization unit, and specifically on a pipeline at 50 bar, for the recycling of the hydrogen (containing hydrogen sulfide impurities). The pipe failed due to…

A sudden fire started in the refinery's hydrocracking unit at the hydrogen compressor of re refinery (India).

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…

The fire occurred on the tube plate gaskets of 3 of the 4 exchangers loaded with catalytic reforming effluent. The fuel (500C and p=30 bar) was a mixture of 30% hydrocarbons and 70% hydrogen. After…

Release of gas from a coking plant on a 20 000 cubic meters gas holder which ignited causing a fire. The accident took place during repair works. The gas was made of 65 % of hydrogen , 25 % of…
