2007年5月24日,挪威Vest Tank公司焦化汽油净化厂中的1台常压储罐发生爆炸,随后引爆其他多个储罐并形成池火,事故共导致2人受伤。该罐区的焦化汽油处理作业主要是用氢氧化钠溶液和水提取出汽油中的硫醇类物质。处理完几只油轮中的焦化汽油之后,脱硫效率就会下降,这是由于沉淀的废物会在储罐中堆积,导致碱液中的杂质慢慢饱和。为对沉积的废物进行处理,废碱液中必须加入盐酸进行中和。在向储罐中加酸后,发生了爆炸。调查
On May 24, 2007, one atmospheric pressure tank exploded in the coking gas purification plant of Vest Tank in Norway and subsequently detonated a number of other tanks and formed a pool fire. As a result, two people were injured. The coking gasoline tanker operations mainly use sodium hydroxide solution and water to extract the mercaptan in gasoline. After the coking gasoline in a few tankers has been processed, the desulfurization efficiency will be reduced because the precipitated waste will accumulate in the tank, causing the impurities in the lye to slowly saturate. In order to dispose of the deposited waste, hydrochloric acid must be added to the waste lye for neutralization. After adding acid to the tank, an explosion occurred. survey
