Deep cooling air separation unit

Sieve tray is one of the most widely used trays in air separation columns. Its main structure is that there are evenly distributed small holes with spacing of 2.1 ~ 3.25 mm and diameter of 0.8 ~ 0.13 mm on the tray. During the operation, the steam bubbling up through the liquid layer through the sieve hole, and the liquid on the tray can only flow in a fixed direction because it is held by the steam. The advantages of sieve tray column are simple manufacture and high efficiency. The disadvantages are that liquid may leak through the sieve hole when the load is too low.

Causes of low air compressor efficiency of small air separation unit   There are many reasons for the low efficiency of air compressors, the common ones are: increase in suction temperature at any level, cooler leakage, decrease in grid frequency or voltage, blockage or increase in resistance of the compressor intercooler, gas leakage due to poor sealing, blockage or increase in resistance of the air filter, blockage or increase in resistance of the pipeline of the air separation equipmen...
