Square activated carbon adsorption box
Thread Content
I would like to ask everyone: do square activated carbon adsorption units have a steam desorption step? Should I just replace the activated carbon directly?
Desorption can be set up, but activated carbon is relatively inexpensive; it is necessary to evaluate whether desorption is worthwhile
A relatively large amount of activated carbon is used, and it’s not suitable to replace it. Previously, circular storage tanks were used, but now the user wants square ones. I’m not sure how square tanks can withstand steam at a pressure of 0.2 MPa. If you have any insights on this, please let me know.
For desorption, a device is also needed to recover the material after desorption, and this recovered material must be treated as hazardous waste, which represents an additional cost; it is not necessarily cheaper than replacing the activated carbon. As for the issue of pressure resistance of the equipment, I am not an expert in this field, but from what I understand, rectangular-shaped equipment generally does not have sufficient pressure resistance
Just calculate based on pressure; many ultra-high pressure devices are square in shape.
Hello! This requires reference to the principle of your company’s activated carbon adsorption unit; if activated carbon is used alone for adsorption, it is sufficient to simply replace it once it becomes saturated! There are also those that use catalytic combustion; these also need to be replaced, but less frequently, as the activated carbon undergoes desorption under 120°C steam, which gives them a longer service life!
That is, when desorption takes place, can the square carbon canister withstand the pressure of the steam? The desorption steam pressure at present is approximately 0.15 MPa.
I don’t quite understand this! After all, I only work with activated carbon; I don’t know much about the specific parameters of the equipment!
