Why does the gas enter the adsorption tower from the top during the adsorption process? Can’t figure it out

Under normal circumstances, it is from bottom to top, unless there are special process requirements, such as temperature-dependent adsorption or something similar

Connecting electric heaters to the concept of adsorption, I think it is done in order to allow the gas to come into contact with the adsorbent and thereby improve the efficiency of use of the adsorbent

I’m very grateful for the answer from above, but I personally think it doesn’t seem quite appropriate

Generally, it is from the bottom in and from the top out, unless there are special considerations, but that is rare. Additionally, the structure of the container matters; what appears to be from the bottom in and from the top out from the outside may not be the case inside the container.

Hehe, maybe the installer turned the drawings upside down when installing them back then. Hehe

It would be best if you provided the specific processes and media you’re talking about so we can analyze them; it’s not possible to explain things clearly just like this.

What I actually mean is the molecular sieve dehydration process for natural gas – the natural gas containing water enters from the upper part of the molecular sieve dehydrator, and it flows out from the lower part? I don’t know why? Hehe, please give me lots of advice. Thank you

I work in automatic control at PSA; this is the first time I’ve seen this. Looking forward to your answers
