Case Study: Pasadena Plant LAO Fire 个案分析： PASADENA厂LAO车间火灾 BP Pasadena Plant, owned and operated by Albemarle Corp. in 1992 at the time of the incident. BP在Pasadena的工厂1992年事故发生时的场景，当时该厂属于Albemarle 公司并由该公司运营。 (see notes for incident description) （详见备注中的事故描述内容） Case Study: Pasadena Plant LAO Fire 个案分析： Pasadena工厂LAO车间火灾 A HAZOP had not been performed on the process. 没有对工艺流程进行过HAZOP分析。 How could a HAZOP study of the process have helped prevent the incident? 对工艺流程进行HAZOP分析，为何有助于预防发生该事故？ HAZOP would have found that there was only one valve between a high pressure process and the low pressure system flush system. Misalignment or leaking valve could overpressure the low pressure flush system. 经过进行HAZOP分析，则可能会发现在高压工艺系统与低压系统冲洗系统之间只有一个闸阀。闸阀安装不当或者出现泄漏则会增加低压冲洗系统的压力。 HAZOP would have found that the low pressure flush system needed relief protection. 如果进行HAZOP分析，则可能会发现应在低压冲洗系统里安装减压保护装置。 Case Study: Pasadena Plant LAO Fire 个案分析： Pasadena工厂LAO车间火灾 How could a HAZOP study of the process have helped prevent the incident?:对工艺流程进行HAZOP分析，为何有助于预防发生该事故？ 3. The high pressure ethylene feed line ran directly over the pumps containing pyrophoric chemicals. HAZOP would have identified the potential for ethylene decomposition if the line was exposed to fire. HAZOP would have identified a lack of ability to isolate the ethylene feed line 高压乙烯进料生产线直接布置在装有自燃化学物品的泵站上方。如果经过HAZOP分析，则可能会发现当该生产线与火接触时可能会导致乙烯分解。通过进行HAZOP分析，则可能会发现缺少了隔离乙烯生产线的保护性措施。 4. The deluge system for the pump failed in the initial fire. A HAZOP review of the deluge system would have identified components that would fail under fire conditions 泵站的集水系统在火灾发生之处工作失灵。如果对该集水系统进行HAZOP分析，则可能会查找出遇火失灵的工作部件。 Case Study: Pasadena Plant LAO Fire 个案分析： Pasadena工厂LAO车间火灾 Each of the listed items were contributing factors to the escalating fire. 以下所列每一项内容都导致火势升级。 The chain of events that led to the fire could have been broken by conducting a HAZOP, identifying the hazards, and addressing
