What is the ratio of the molecular sieve loading to the volume of regeneration gas?

Dear sea friends, is there any specific regulation regarding the ratio between the tonnage of molecular sieve used and the volume of gas used for regeneration? If 9 tons of molecular sieve are used, what should be the volume of gas required for regeneration?
This question is a bit complex; only the designers can explain it clearly. It really depends on what type of molecular sieve you are using Parameters such as the shape of the molecular sieve and the temperature of the regeneration gas also need to be considered!
13XAPG4*8 is spherical in shape; the regeneration temperature is 185°C for the heater, and 140°C for cold blowing with a molecular sieve℃
The loading capacity is primarily calculated based on the air treatment volume of the adsorber and the designed inlet temperature; it has little to do with the regeneration gas. Of course, the volume of the regeneration gas can generally be used to determine the corresponding air treatment volume. The requirements for the parameters of the regenerated gas in a single-layer bed with two layers and two pairs are different; it is not necessary to maintain a fixed temperature and flow rate – as long as thorough regeneration takes place. The amount of molecular sieve to be used is calculated based on its adsorption properties, and a margin is taken into account depending on the size of the air separation unit. There are many factors to consider in the design, such as flow rate and the adsorption capacity under dynamic and static conditions. From a purely technical perspective, there’s no need to delve too deeply into it; just have a general understanding
Regeneration is a bit excessive~~ Increasing the adsorption time or reducing regeneration can help the purification system save energy and reduce consumption~~ The relationship between the loading amount and the volume of inlet air isn’t clear~~ However, the amount of nitrogen contaminated as a result of regeneration accounts for 16–22% of the volume of inlet air~~
If there are any abnormalities or issues with your current air separation project, you can provide the parameters of that project, and I can calculate them for you. Leave your email address and I’ll send you the required parameter table.

To know the gas impurity content, the yield, the adsorption time, etc., as well as the composition of the regenerated gas – what’s key is to be aware of the relevant processes
It’s more convenient to calculate using the processed air volume. The conversion factor is 0.13. If the set value for the regenerated gas volume is: = Air volume Q * 0.13
Regenerated gas is also related to the process; it depends on what kind of process you are using, as well as on whether it is zero-gas-consumption regeneration or forced-air heat regeneration. There are quite a few factors. If you want to determine the specific regeneration volume, you can use a flow meter for measurement. However, domestic manufacturers all claim that their regeneration volume is low, and the regeneration volume is also closely related to the dew point of the finished gas.
