Faq of Maintenance of air separation unit

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.

Internal compression air separation process is a process form in which liquid products are pressurized by liquid pump in the cold box, and then sent out of the cold box after reheating by high-pressure heat exchanger. The working pressure of internal compression process generally exceeds the critical point of oxygen and nitrogen. Heat transfer of liquid in supercritical state is a major feature of internal compression process. In the distillation process, due to the difference of product types and acquisition methods, there is a big difference between the material import and export of internal equipment and external compression process. In the internal compressed air separation process, the pressure of oxygen is not limited, the maximum output of nitrogen can reach 2.8 times of that of oxygen, and the extraction rate of argon can reach about 85%. The internal compression air separation process is generally composed of internal compression system, air precooling system, molecular sie
