空分设备上除主冷凝蒸发器会因碳氢化合物的浓缩积聚而发生爆炸事故外,粗氩冷凝蒸发器和纯氮设备的冷凝蒸发器也是碳氢化合物的浓缩积聚区,也应引起足够的重视。文章提出在这类富氧液空冷凝蒸发器结构设计和运行操作中的注意事项。
Air separation plant in addition to the main condensing evaporator will accumulate as a result of the accumulation of hydrocarbons exploded, the crude argon condensing evaporator and condensing evaporator of pure nitrogen equipment is also a hydrocarbon accumulation area, should also cause sufficient Pay attention. The article puts forward the precautions in the design and operation of the structure of the oxygen-enriched liquid-air condensing evaporator.
