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.

Membrane separation is a technology that uses separation membranes as the core for the selective separation, concentration and purification of substances. The basic principle is to use the different rates of dissolution and diffusion of each gas component in the separation membrane at a certain pressure, and therefore the different rates of permeation through the fibre membrane walls due to the partial pressure d...
