“A high \"vacuum level\" causes the air separation unit to shut down
Thread Content
In air separation units, a high vacuum level can cause the unit to stop operating, which in turn leads to a shutdown of the entire plant. Could someone explain what exactly \"vacuum level\" means and what causes it to be high? Thank you so much! !
In my understanding, a vacuum condition occurs when the air flow entering the air separation unit is blocked. In large units, filters are usually installed at the air inlet to prevent dust and impurities from entering the system. Over time, these filters get clogged with dust, which prevents proper air flow to the compressor. This results in a vacuum condition. In order to supply enough air to power the subsequent equipment, the compressor has to work harder, leading to an overload situation that causes it to shut down, thereby stopping the operation of the equipment.
What was said upstairs is correct; generally, large air compressors have filter elements arranged in an array, and these need to be maintained and replaced
