Too low a flushing volume can also result in a low processing capacity.
1. The adsorption pressure may decrease. 2. The adsorption temperature rises. 3. The quality of the adsorbent is poor and needs to be replaced. 4. Regeneration is incomplete, resulting in high backpressure
The adsorption, decompression, and equilibrium setting times are influenced by temperature, pressure, as well as the quality of the molecular sieve and the structure of the adsorption tank; therefore, they need to be reset according to the prevailing conditions. The time set by manufacturers is generally sufficient in the early stages of equipment operation, but it needs to be reset as time goes by.
There is a problem with the molecular sieve in the adsorption tower.
The molecular sieve was not installed properly, it leaked, and the yield decreased. Or the molecular sieve may be poisoned, resulting in a decrease in yield per unit. Or. . . There are quite a few possibilities
