What problems should be paid attention to in the process of storage and transportation of liquid storage tank?

The brief introduction of the air filter and air compressor in this process is the same as that of the chilled nitrogen production process. 1. Cold dryer: it is an air separation equipment used to reduce the temperature of compressed air before entering the air drying purifier to extract oil and water. It usually adopts post cooler with the structure of column pipe type, casing type, cooling sheet type and so on. 2. Oil-water separator: its function is to separate the oil and moisture contained in the compressed air and make the compressed air get Primary purification. 3. Air drying purifier: Compressed air still contains certain moisture after passing through the post cooler, and its content depends on the temperature of the air. The drying process of compressed air generally adopts molecular sieve absorption method and freeze drying method. 4. Pressure conversion absorption nitrogen generation device: the adsorbents used are usually 5A Molecular sieve or carbon molecular sieve, an...

The distillation column is an air separation equipment equipped with multi-layer tower plates (the working principles of the sieve Tower and the packing tower are the same. There is a liquid layer with a certain thickness on the tower plate. The distillation column is usually a two-stage distillation column, which is divided into two parts: the upper tower and the lower tower. Compressed air is sent to the lower part of the lower tower as the rising air after the moisture and carbon dioxide are cleared and cooled and expanded in the heat exchanger (the medium pressure process. Because it contains 21% oxygen, the corresponding saturation temperature is 100.05K at 0.6MPa. The liquid nitrogen condensing in the condensing evaporator flows down from the top of the lower tower as the recirculation liquid. Because the oxygen content is 0.01% ~ 1%, the saturation temperature at 0.6MPa is about 96.3 K. Thus it can be seen that the rising steam temperature at the bottom of the distillation to...
