Hydrochloric acid tank explosion


  • Initially prepared for presentation at the American Institute of Chemical Engineers, 2008 Spring National Meeting 42nd Annual Loss Prevention Symposium New Orleans, LA, April 7–9, 2008.


Explosions in hydrogen chloride storage tanks are very rare. However, we have experienced one. The explosion was so powerful that the tank with a capacity 250 kL, 60% filled with 33% HCL, took off from the ground went up to 8–9 m high in air and landed around 50 m away. The contents of the tank sprayed all over the nearby area. Though the tank was surrounded by other plants and equipment, fortunately, it landed in a barren area. This averted loss of life and property that would have otherwise resulted. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009
