Regeneration cycle of dry desulfurization adsorbents

This post was last edited by sdwfsgyykai on 2019-6-29 07:54. What determines the regeneration cycle of dry desulfurization adsorbents? Are there any specific standards or calculation formulas for this? Thank you
It would be best to provide more detailed information on the specific desulfurization processes and desulfurizing agents
Dry desulfurization: it is used after adsorption becomes saturated, and steam is used for regeneration; how is the length of this regeneration cycle determined?
In my opinion, the key factor is the adsorption efficiency; if this efficiency drops significantly, regeneration is necessary
Based on the sulfur content, during testing, make adjustments to see that the sulfur content decreases after a few hours, which indicates that the desorption has been completed; at that point, simply switch the adsorption valve
It’s also necessary to calculate the heat balance, which seems quite complicated; in other words, the heat required to raise the temperature of the adsorbent must be balanced with the heat of the cooling medium
It’s necessary. Another approach is to install an online analyzer at the outlet; in this way, once the regeneration temperature is set correctly and the analysis data shows satisfactory results, the regeneration is complete
