空分设备设计风险识别与本质安全设计

RISK INDENTIFICATION AND INTRINSIC SAFETY DESIGN OF AIR SEPARATION PLANT

以冷箱泄漏与主冷凝器燃爆风险为例,阐述空分设备在设计阶段时,应充分识别并有效评估工艺流程中存在的风险因素。通过采取相应的防控措施,尽量减少甚至消除影响空分设备安全稳定运行的危险源,实现空分设备的本质安全设计。

Risk factors in the process should be fully identified and effectively assessed during the design phase of air separation plant.In this paper,measures which were taken to avoid cold box leakage and main condenser explosion,were described as examples.By taking corresponding measures,these factors which affected the safety and stable operation of air separation plant,could be reduced or even eliminated to achieve the intrinsic safety design of air separation plant.
