Adsorption process and system using multilayer adsorbent beds containing regenerator section

摘要

For PSA or TSA prepurifiers, the temperature rise on adsorption is particularly troublesome when the temperature rise reaches the end of the bed at the end of the adsorption step. This results in an increase in the CO₂ and N₂O concentration at the end of the cycle. Addition of a regenerator in the middle of the adsorption layer will reduce the temperature rise at the end of the bed and thus enhance the performance of the bed.
