我公司化工一厂的空分装置位于厂区内,空气就地吸入。由于受到周围裂解、乙二醇、制苯等装置的污染,吸入口空气中含碳氢化合物较高,在液氧中积累后导致1986年1~#空分爆炸事故。恢复生产后仍然面临两个问题:一是厂区大气条件没有改善,需解决原料空气的净化问题,找出符合实际的净化途径;二是虽然制定了液氧中碳氢化合物含量的控制标准,但对该标准的可靠性还没有十分把握,对标准制定的依据也需要进一步了解。
I plant a chemical plant air separation plant located in the factory, inhaled air in place. Due to the surrounding cracking, ethylene glycol, benzene and other pollution devices, inhaled air containing hydrocarbons higher in liquid oxygen accumulation led to the 1986 1 ~ # air separation explosion accident. After the resumption of production, it still faces two problems: firstly, the atmospheric conditions in the factory area have not been improved, and the problem of purifying the raw air needs to be solved to find a practical purification approach; secondly, although the control standard for the content of hydrocarbons in liquid oxygen has been formulated, The reliability of the standard is not yet fully understood, the basis for the development of standards also need to learn more about.
