If the cooling capacity is high, how can oxygen production be increased without reducing that cooling capacity, yet the argon fraction still cannot be high?
If the cooling capacity is high! The main cooling rate is increasing rapidly, and the resistance at the top of the tower is rising! 1. Increase the pressure in the lower tower (increased gas flow, improved purity of liquid oxygen), but energy consumption increases ； Increase the temperature difference in the main cooler to boost the evaporation rate of liquid oxygen; if it is possible to discharge liquid nitrogen, do so in appropriate amounts (to appropriately reduce the resistance in the upper column) in order to prevent the main cooler from overheating too quickly. 3. Test the oxygen content in the contaminated nitrogen gas; if it is high, it can be reduced appropriately. Pre-cooling and molecular sieves are sufficient! Dirty nitrogen can also be used to control the pressure in the upper column, ensuring an appropriate heat exchange ratio between the liquid flowing downward and the gas rising upward.
