Air separation

I want to lower the tower pressure. The liquid guide of the air compressor isn’t moving, and the product flowing out of the upper tower isn’t moving either. Is it okay to increase the flow of liquid nitrogen via V11 to send it back to the lower tower? Why? Thank you all.
It is safer to directly reduce the outlet pressure of the air compressor in order to lower the pressure in the lower column.
Mm. Thank you. If the pressure of the air compressor drops, then won’t the production volume decrease?
Is it to lower the temperature of the circulating water? Are there any other good ways to reduce the outlet pressure of the air compressor? ? I’m seeking advice.
Lower the circulating water temperature? ? What is the control method for your air compressors? Does the air compressor not have vanes?
There are some. If I reduce the import flow rate, the pressure at the compressor outlet will drop, and the pressure in the lower column will also decrease, but the amount of air flowing will be reduced. I don’t want the amount of air to decrease. Is there any way?
Someone suggested that I increase the V11 value, but I just can’t figure out why there’s any reason to do that I’m seeking advice.
Try to open the lower reflux liquid valve wider.
The lower reflux liquid valve V11 was opened further, but the effect was not significant. Could you explain to me the principle behind opening V11 further?
Add a return valve to increase the air intake flow. A decrease in the outlet pressure of the air compressor reduces the flow rate; increasing the reflux valve increases the flow rate. Stay steady.
