Dust removal efficiency of sieve tray tower

1.Before filling alumina and molecular sieve adsorbent into the adsorber, personnel should be arranged to enter the adsorber to check whether the screen screen is damaged. If there is any damage, it must be repaired before filling. 2.The quantity of adsorbent should be counted during loading and unloading, and the packing barrel and bag of adsorbent should be prevented from being damaged, and the adsorbent should be prevented from getting damp due to poor sealing. 3.The molecular sieve in the container should be filled in dry weather without rain. Personnel entering the container shall wear oil-free work clothes and caps and clean soft soled shoes.

When the power supply of the air separation unit of the molecular sieve adsorption purification process is resumed after the power failure, the operation should be conducted according to the following steps: 1) the possible influence on the mechanical equipment such as the air compressor when the power is suddenly cut off should be judged. If there is no influence, start-up preparation of the air compressor according to the operation specification of the air compressor; 2) check and confirm the switch state of the chain shutdown equipment valve; 3) check and confirm the alarm chain project of the air separation plant. Re-check and confirm the chain control of failure during power failure; 4) start the air compressor and air precooling system according to regulations; 5) start the molecular sieve adsorber according to regulations. Continue to complete the process before shutdown. If the downtime is long (more than 24 hours), the molecular sieve adsorber should recycle for one cycle; ...
