Fire in bulk hydrogen storage compound. Pressure gauge shut off valve spindle blown out (could be completely unscrewed and removed). The subsequent leak ignited by unknown source. No injuries sustained by personnel. Fire extinguished by station staff.

Malfunctioning of the non-return valve of the hydrogen compressor has caused the pressure between the hydrogen bottle and the compressor to rise to the maximum allowed pressure of 275 barg.

A fire broke out affecting the heavy fuel purification plant of the refinery.The incident could have originated by the failure of one of the following plant components:- pipes leading to the pressure gauges of the reactor - recycled gas pipe at the bottom of the reactor having a quench function,- diatermic oil pipe (hot oil) entering or exiting the exchanger- flanged joints exchanger and connection lines.On the base of and data logging and video evidences, the company excludes a release from the hot oil circuit as the triggering factor of the fire.

An over-dosage of natron lye in a silicon dust suspension container raised the ph-value up to 11, producing large amounts of hydrogen in a short time. The hydrogen caused an extreme pressure increase in the container which consequently burst. The expanded hydrogen ignited immediately on contact with the atmosphere.The explosion destroyed and blew away plant parts (containers, ceilings, supports) causing damage in the surroundings.

During the polymerization of ethylene in a 750 liters pressurized reactor, an exothermic runaway decomposition occurred and ethylene and its decomposition products were released through the two reactor vent stacks and via the dump valves on the supply lines. The released gas (cloud) was ignited apparently by the hot carbon particles obtained by the decomposition of the ethylene and an aerial explosion occurred. The following substances were involved in the accident: Ethylene (60 kg). Ethylene (together with the decomposition products about 60 kg).

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 methane , 4.1 % of carbon monoxide and carbon dioxide . About 100 firemen fought the fire with water nozzles. Fire was extinguished within 45 min. A safety area was set up. Because of the toxicity of the gas, about 40 people were evacuated. No consequence to the environment nor people. However, loss of production was significant.

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 is the reduction of an imide compound to an amine compound in anhydrous medium in presence of (AlCl3) activated sodium tetrahydroborate. The reaction is performed in an ether solution and the reactor is nitrogen inerted. - The imide compound is introduced in the reactor via a flexible pipe connected with a mobile pneumatic dosing pump.

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 lining (inner coating), and the release of feed (raw, initial) substances and partly transformed substances and reaction products through the top of the reactor.
