浅谈空分装置密封气泄漏过大引起的危害

Discussion on Harm Caused by Excessive Leakage of Seal Gas in Air Separation Unit

空分冷箱密封气的用途主要是保持空分冷箱保持正压,防止潮气进入,使冷箱内的珠光砂保持干燥。干燥的珠光砂保冷效果相对较好,空分系统的冷损就小,相对能耗就低。密封气一定要用干燥污氮,切实保持空分装置安全运行。

The sealing gas of the air separation cold box is mainly used to keep the air separation cold box at positive pressure,prevent moisture from entering,and keep the pearlite in the cold box dry.The cold insulation effect of the dry pearlite is relatively good,the cold loss of the air separation system is small,and the relative energy consumption is low.Dry waste nitrogen must be used as sealing gas to ensure the safe operation of air separation unit.
