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 man...
