The naphtha and hydrogen gas leaked out from the gasoline reformer at the Southwest Petroleum as the relief-valve was operated after its repair.Although the source (Asian database ADRC) does not…

In a residual-oil hydrotreatment unit (also called residual oil hydrogenation) plant, a hydrogenation unit caught fire with a huge bang, followed by a fireball in the form of a mushroom cloud. Black…

A 7 inch thick reactor of a wide range hydrocracking unit being operated by computer at 2500 psi failed explosively due to localised heating. The blast caused widespread damage over a 300 yard radius…

Two employees were working on a electric furnace under hydrogen atmosphere that had jammed. The furnace exploded. The employees sustained flash burns to their faces and were taken to the hospital,…

The explosion occurred at the hydrogen producing unit of a refinery.A solution of potassium carbonate was being drawn off from an absorption tower to a temporary storage tank for a turnaround…

On September 1, 1992, an explosion in this facility occurred due to an accidental release of hydrogen at the Institute of Energy Conversion, University of Delaware, US. Hydrogen gas was used in…

Hydrogen gas explosion blew the lid off a heavy container at a heat treatment and brazing plant, crushing one workers hand.

The day before the incident, the outlet pipe connected to methanation reactor started leaking gas, which contains hydrogen. The leak was temporarily eliminated by a pressurised plug. On the day of…

A gas mixture (25% nitrogen, 73% of hydrogen, 2% methane) leaked, due to the ejection of the check valve from its connection with the inlet pipe. A large amount of the gas mixed with air and ignited…

An explosion at a refinery Hydrotreater plant involving a furnace and hydrogen caused by faulty operation. Source of ignition was furnace.

Explosion at styrene plant during start-up. A manhead flange failed in a light oil hydrogenation unit releasing 30 kg of hydrogen in a compressor shed. Ignition occurred in 10 to 15 secs.…

Explosion due to hydrogen gas leakage from an abraded pipe: A hole was made in a pipeline used for catalyst regeneration at an aromatics plant, ejecting catalysts and hydrogen gas which ignited.…

The event occurred at a de-sulfurisation reactor unit. Hydrogen leaked into the reactor causing an explosion. The Fire spread rapidly.

This incident occurred unit at a demonstration of a new technology for the catalytic cracking of vacuum residual oil. An oil storage tank failed due to high pressure. The overpressure in the tank was…

The incident affected at an indirect oil desulfurization unit, and originated at a piping at the outlet of a heat exchanger. The exchanger was located in the furthermost downstream of the reactor.…

An explosion at a refinery started a fire that was fueled by diesel and hydrogen.

A fire and explosion occurred at a catalytic reformer unit. The fire centred between the reactors and fired heaters of the reformer and resulted in extensive damage to the unit.The explosion rocked…

The accident occurred in the cracking unit and in the sulfur recuperating system, more exactly in a 90 curve of a 8" piping. Due to the crack of the curve a mixture of flammable gases was released…

The accident started with a leakage of distilled petroleum intermediate and hydrogen in the desulfurization unit of the distilled intermediate. Both substances ignited and exploded, with a later…
