What can happen to the DEAR Liquid air separation unit forced valve itself?

How is the relation between expander and refrigerating capacity of air separation equipment?

In medium and large air separation plants, the purification system is an important part when separating oxygen, nitrogen and argon from air. The purification system commonly uses molecular sieve adsorbent to adsorb moisture, carbon dioxide, hydrocarbons, etc. in the air. The molecular sieve purification system plays an important role in the air separation equipment process to ensure safety. The molecular sieve purification system is generally composed of adsorber, electric heater, pipeline, val...
