摘要

1994年12月13日,两次大规模爆炸将印第安纳州苏城附近的硝酸铵工厂部分夷为平地。据称,第一次爆炸发生在中和器容器内设计有缺陷的钛喷撒管中。然而,调查显示,爆炸的发生是由于不安全的工厂操作和不良的维护程序。具体来说,容量为18000加仑的中和剂容器内的硝酸铵受到污染,呈高酸性。操作人员随后将过热蒸汽直接注入中和器容器中的硝酸铵。

Explosion of the Terra Ammonium Nitrate Plant, Port, Neal, Iowa
On 13 Dec 1994, two massive detonations leveled portions of an ammonium nitrate plant near Sioux City, IA. The primary explosion allegedly occurred in defectively-designed titanium sparger piping inside the neutralizer vessel. Investigation however, revealed the explosion occurred because of unsafe plant operations and poor maintenance procedures. Specifically, the ammonium nitrate within the 18,000 gal capacity neutralizer vessel had become contaminated and made highly acidic. The operators then injected superheated steam directly into the ammonium nitrate in the neutralizer vessel.
