Hexane and other volatile hydrocarbons (petroleum ether) present an aspiration risk. [26] n-Hexane is sometimes used as a denaturant for alcohol, and as a cleaning agent in the textile, furniture, and leather industries. It is slowly being replaced with other solvents. [27] Like gasoline, hexane is highly volatile and is an explosion risk.
The Ralston-Purina plant used hexane as a solvent to extract oil from soybeans. The plant employed a containment system designed to recycle used hexane from the process back to the plant. However, the containment system was not functioning that night, and a large quantity of hexane was released into the sewers.
When including settlements ($2.1 billion), costs of repairs, deferred production, and fines, the explosion is the world's costliest refinery accident. The direct cause of the explosion was the ignition of a heavy hydrocarbon vapor cloud which emanated from raffinate liquids overflowing from the top of a blowdown stack. The source of ignition ...
Dusts also have upper and lower explosion limits, though the upper limits are hard to measure and of little practical importance. Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds ...
The explosion appeared to have been in the general area of the reactors and after the accident only two possible sites for leaks before the explosion were identified: "the 20 inch bypass assembly with the bellows at both ends torn asunder was found jack-knifed on the plinth beneath" and there was a 50-inch long split in nearby 8-inch nominal ...
A BLEVE–fireball at the Philadelphia Energy Solutions refinery, as rendered by the CSB. A boiling liquid expanding vapor explosion (BLEVE, / ˈ b l ɛ v iː / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that is or has reached a temperature sufficiently higher than its boiling point at atmospheric pressure.
On 2 April 1916, an explosion blew through the gunpowder mill at Uplees, near Faversham, Kent, when 200 tons of TNT ignited. 105 people died in the explosion. The munitions factory was next to the Thames estuary , and the explosion was heard across the estuary as far away as Norwich , Great Yarmouth , and Southend-on-Sea , where domestic ...
The explosion occurred at 11:06 p.m., [note 1] during the show's finale. [7] [2] The explosion was centered on the southeastern end of the arena, [8] [3] [9] just underneath the box seats of Aisle 13. [10] [3] [4] The initial blast lifted approximately 700 square feet (70 m 2) of floor and launched debris and spectators towards the ice rink. [8]
