Molecular sieve regeneration
Thread Content
Molecular sieve regeneration stage: 1. During the pressure relief phase, the temperature at the inlet of the adsorber decreases gradually. What is the reason for this? What causes the temperature changes at the various red-line marked areas in the graph? Thank you to the expert for the answer:):)
During the pressure release phase, the pressure decreases; the regeneration of the molecular sieve is endothermic. Since no external heat is available, only the heat generated by this regeneration process is utilized, which leads to a drop in temperature. As a result, the pressure can drop to negative values
The sixth red line is pressurization, which takes place at the adsorption inlet side.
A decrease in pressure leads to volume expansion, which results in cooling
