"10 · 27" Explosion Accident of Heilongjiang Daqing Petrochemical Complex

On October 27, 2004, an explosion accident occurred in the sulfur recovery workshop of the refinery of Daqing Petrochemical Company, causing 7 deaths and 1.92 million yuan of economic loss. The direct cause of the accident is that the gas (hydrogen, hydrocarbons) in the raw water tank leaked from the root weld of the DN200 pipeline connected to it or the weld joint connecting to the tank roof cracked when the gas welder, under the guidance and cooperation of the production unit, was engaged in hot cutting at 0.8m from the exhaust line on the top of the raw water tank of the sour water stripping unit, and the explosion was caused by gas cutting open fire or splashed slag.

"10 · 22" LPG deflagration accident in Shanghai Gaoqiao Petrochemical Refinery

On October 22, 1988, a liquefied gas deflagration accident occurred in Xiaoliangshan spherical tank farm of the refinery of Shanghai Gaoqiao Petrochemical Corporation, resulting in 26 deaths and 15 burns. The direct cause of the accident was that the operators in the spherical tank area of the oil product workshop of the plant were opening the valve to dewater a liquefied spherical tank. The operators did not operate according to the regulations and dewatered while feeding, which led to the discharge of water and liquefied gas together. A large amount of liquefied gas escaped through the sewage pool, and the escaping liquefied gas spread with the wind. The fire was caused by the open fire in the heating furnace in the temporary shed outside the enclosure of the spherical tank farm.

"10 · 22" explosion accident of Inner Mongolia Zhonggao Chemical Co., Ltd

On October 22, 2021, an explosion accident occurred in Inner Mongolia Zhonggao Chemical Co., Ltd. located in Alxa Hi tech Industrial Development Zone, causing 4 deaths and 3 injuries. The direct cause of the accident is that during the operation of the enterprise to deal with the blockage of the pipeline of the evaporation discharge pump, the magnetic circulation pump inhaled air, causing the material in the pump cavity (the mixture of 2-nitro-4-methylsulfonyltoluene and 2-nitro-4-methylsulfonylbenzoic acid) to cut off the flow, the material in the pump cavity decomposed and exploded in the presence of high temperature, causing the valve at the bottom of the oxidation evaporation tank to break, and the high-temperature material in the oxidation evaporation tank encountered an explosion residual open fire after venting, resulting in flash explosion and combustion.

Fire and explosion accident of BASF Chemical Plant in Ludwigshafen, Germany

On October 17, 2016, a fire and explosion accident occurred in the chemical plant of BASF headquarters in Ludwigshafen, Germany, resulting in 2 deaths, 6 serious injuries and 2 disappearances. The death toll rose to 5 in the following year. The explosion first occurred on a supply line connecting the port and the oil depot in Ludwig Port, and then the fire spread to other equipment, which also led to the closure of the adjacent steam cracking unit. The direct cause of the accident: the contractor's personnel cut the wrong pipe when using the angle grinder to cut the pipe, and the sparks generated by the cutting ignited the residual butene mixture in the pipe, causing explosion and fire.

Deflagration accident of natural gas treatment plant in Louisiana, USA

On October 8, 2015, a burning explosion accident occurred in Gibson Wellhead Natural Gas Treatment Plant affiliated to the transcontinental natural gas pipeline transportation company of Williams Partners near Homa Town, Louisiana, USA, resulting in four deaths and one serious burn of the maintenance contractor's employees. The cause of the accident was that a mucus trap under repair (a tank used to separate liquid and impurities from the natural gas stream) had pipe rupture and leakage, which led to explosion and fire. The fire continued to burn for nearly 3 hours.

Fire and explosion accident of Lichuan ABS resin plant in South Korea

On October 4, 1989, a fire and explosion accident occurred in the ABS resin factory of Korea Happiness Company in Lichuan, resulting in 14 deaths, more than 20 injuries and a direct economic loss of about 3 billion won. A few hours before the accident, a large amount of powdered resin leaked from the canvas covered on the upper part of an extruder. At the same time, the powdered resin enters between the extruder hood and the electric heater, contacts with the electric heater, and is heated and decomposed by the surface of the electric heater to produce combustible gas. The combustible gas generated diffuses to the first and second floors, causing continuous explosion.
