In general, the liquefaction temperature of nitrogen is higher than that of oxygen, but why can the condensation evaporator between the upper and lower columns of the air separation column use gas nitrogen condensation to release heat to vaporize liquid oxygen? This is because we usually think that the liquefaction temperature of nitrogen is lower than that of oxygen under the same pressure. However, the pressure at the bottom of the upper column of the air separation unit is generally 0.149 MPa, and the pressure at the top of the lower column is about 0.58 MPa. The reason for the different pressure causes the inversion of the saturation temperature of oxygen and nitrogen. It is precisely by using this principle that the condensing evaporator can continuously provide liquid nitrogen for the lower column At the same time, it provides gas oxygen for the upper column as the rising gas to participate in fractionation.

If the passing capacity of the liquid-air regulating valve selected in the design is too small, or it is replaced with the liquid nitrogen regulating valve incorrectly during installation, or the regulating valve, liquid-air adsorber and supercooler are blocked during operation, it can reduce the passing capacity of liquid air. Even if the regulating valve of the liquid level is opened to the maximum, the liquid level of the liquid level will continue to rise. In order to maintain the stability of the liquid level of the lower tower, we have to adopt the method of enlarging the liquid nitrogen regulating valve to reduce the reflux liquid of the lower tower, which will destroy the normal rectification working condition of the lower tower. Because the amount of liquid nitrogen is too large, the purity of liquid nitrogen decreases, and the purity of nitrogen in the upper tower also decreases, the extraction rate of oxygen decreases, and the output of oxygen decreases. At the same time,...
