Why does the pressure drop after the pressurized air enters the distillation tower?
Thread Content
After the pressurized air undergoes heat exchange in the heat exchanger and enters the lower section of the distillation tower, its pressure drops significantly. Why does it drop? What is the process of reduction? This post was last edited by jh56565656 on 2007-12-20 22:17.]
I can’t understand what the landlord is trying to express; please explain in detail!
Could the person asking the question please be more clear? I can’t understand it
1. If the outlet pressure of the booster is normal: in cryogenic air separation, during long-term operation, due to inadequate regeneration of the molecular sieve or prolonged operation, trace amounts of carbon dioxide or other impurities may be introduced, which can cause blockages in the heat exchangers or a reduction in their channel sizes. This leads to an increase in pressure difference, and as a result, the pressure of the pressurized air after passing through the heat exchanger decreases before it enters the lower section of the distillation column. It is recommended to park and thaw/rewarm. 2. If the outlet pressure of the booster decreases: switch the booster and check it ； Check the anti-surge valve.
If the pressure of your air remains normal after exiting the heat exchanger, but drops after the pressurized air enters the distillation tower, then it means there has been an increase in resistance inside the tower. In other words, the tower is partially blocked. The likely reason is that the moisture content in your air is too high; when it enters the distillation tower, it causes partial freezing. Solution: 1. Enhanced regeneration of the desiccant in the air drying tower. 2. The distillation tower is flushed with dry gas to remove frost.
