Is there any danger when disassembling or loading the activated carbon filler in an activated carbon adsorption tower?

This is determined by the physicochemical properties of the activated carbon adsorbent. Different activated carbon adsorbents may contain certain active components derived from impregnation processes (such as elemental metals, oxides, etc.). Therefore, before loading or unloading them, it is necessary to first determine the type of adsorbent and familiarize oneself with its Material Safety Data Sheet (MSDS), in order to develop an appropriate loading procedure. 1) During loading, issues such as purging and displacement, oxygen content, combustible gas concentrations, falls from heights, dust generation, entry of people into confined spaces during filling, asphyxiation, and fire prevention are all factors that need to be taken into consideration ； 2) During unloading, it is even more important to check whether the adsorbent has been fully regenerated, whether any residual adsorbates are toxic or harmful, and whether there are any flammable or explosive gases or liquids remaining in the tower

When we repaired the purification tower last year, nitrogen displacement was used in the process and the results of the tests were satisfactory; however, spontaneous combustion and heating of the activated carbon still occurred during on-site disassembly. It is recommended that you conduct a thorough analysis of the medium used for activated carbon adsorption and develop an appropriate plan.

If there is a fever, there is still some risk, right?

Could you explain it in more detail? Generally, heat is released during the adsorption process, which poses a risk of spontaneous combustion. I’m a bit puzzled as to why it caught fire on unloading

What medium is absorbed by activated carbon? What are the physical property data of this medium? Don’t cause any burning or explosions.
