Condensing evaporator leakage
Thread Content
May I ask that when the condenser-evaporator (main cooler) of a distillation tower leaks and nitrogen enters the oxygen side, this will result in a decrease in the purity of both gaseous oxygen and liquid oxygen in the main cooler. Therefore, we can determine the extent of the main cooler leakage by examining the relative degree of decrease in these two purities. But I don’t know which one sees a greater decrease in purity, gaseous oxygen or liquid oxygen?
Analyzing according to the principle of phase equilibrium: A small amount of nitrogen first enters the liquid oxygen; the light components in the liquid oxygen evaporate first, which should have a significant impact on oxygen. It is also necessary to analyze the location of the leak and its relationship with the position of the extraction port.
2# Mauser: I heard from a technician that the purity of liquid oxygen decreases more; I don’t know why
The reason is simple: the pressure at the bottom of the tower is high
4# Song Haoming, sir, what I asked was about the comparison between liquid oxygen and gaseous oxygen, not between liquid oxygen and gaseous nitrogen
It must be that the purity of liquid oxygen is dropping rapidly! !
