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; ...

In the air separation plant, the purity of oxygen is mainly determined by the working conditions of the distillation column at the upper and lower parts. In addition, the oxygen content in argon fraction, reflux ratio, number of theoretical trays and separation efficiency will have a direct impact on the purity of oxygen. The following is a brief introduction to the relationship between these factors and oxygen purity.
