Author: DEAR AST

In case of sudden power failure during the operation of small air separation unit, the following steps should be followed:

 

First, open the vent valve (anti surge valve) of air compressor to prevent the air compressor from surging and causing the air compressor to reverse due to air backflow;

 

Then check whether the molecular sieve adsorber switch should be interlocked to close, if not, it should be manually closed, and record the program status of molecular sieve adsorber before power failure. Expander, refrigerator, air precooling system and argon purification system shall also be shut down by interlocking, if not, manually;

 

Finally, stop the delivery of oxygen and nitrogen products, stop the output of liquid oxygen, liquid nitrogen and liquid argon, and close the water valve of air precooling system and external connection.

Due to improper adjustment of seal gas pressure during operation, liquid oxygen pump can not pump liquid or leak.   From the quality point of view, when the sealing pressure is too high, there will be gas leakage into the pump through the labyrinth seal, resulting in the impeller with gas or even idling, resulting in liquid injection or pressure drop; when the air pressure before sealing is too low, there will be liquid oxygen leakage.   From the quantity point of view, when (p1-p3...
