Size of the air separation unit

Size of the air separation unit
Generally, the size of the air separation unit is measured by oxygen production, and the unit is Nm3 / h, which means how many cubic meters are produced per hour. The size of the air separation plant needs to be selected according to the actual production needs of the enterprise, not the larger the better.

There are mainly the following factors that affect the output of oxygen: 1) insufficient processing air volume. The reasons for the shortage of air volume include: ① the ambient temperature is too high; ② the atmospheric pressure is too low; ③ the air suction filter is blocked; ④ the low voltage or the frequency of the power grid will reduce the rotating speed; ⑤ the cooling effect of intermediate cooler is not good; ⑥ internal leakage exists between levels; ⑦ air leakage of valve and pipeline, and leakage of automatic valve or switching valve; ⑧ for the purification process of molecular sieve, it may be the air leakage of switching butterfly valve. 2) the average purity of nitrogen is too low. The reasons are: ① the efficiency of the distillation column is reduced; ② the expansion air volume is too large due to too much cold loss; ③ the purity of liquid nitrogen is too low and the liquid nitrogen volume is too large; ④ the liquid nitrogen volume is too small; ⑤ leakage of liquid ai...

When the cryogenic method is used for air separation, the whole process is carried out in closed containers and pipelines from the air compressor to the final gas and liquid products such as oxygen, nitrogen, argon and so on. During the start-up, shutdown and normal operation of the equipment, the values of relevant parameters must be strictly controlled in each process, including pressure, temperature, flow, resistance, liquid level, rotate speed, voltage, current, component analysis, etc. The following introduces some instrument control components for measuring temperature, pressure and flow for reference. 1.Temperature measurement: In the temperature measurement of air separation plant, the main measuring elements are platinum thermistor thermometer, temperature transmitter and bimetal thermometer. Platinum thermistor thermometer is widely used in air separation plant due to its high measurement accuracy at low temperature (13.81K) and no temperature compensation at cold end.
