Making a Desiccant Air Dryer with Silica Gel

<< < (4/10) > >>

Perhaps we should run a challenge to find other uses for them  :scratch:

krv3000:
that's a proper job :clap:

Hi there, Andrew,

Another interesting project up and running, I hope you're not neglecting the livestock!

Somewhere in my filing ('piling' ? ) system, I have a copy of the military specification for the handling and re-activation for silica gel (hasten to add - it's not classified!).

I was always happy with the process when the domestic oven was electric but, nowadays, we cook with gas.

Does anyone know if that's as effective as the electric oven?  (I'm assuming that burning domestic gas produces water vapour.)

John Rudd:
I've worked with silica driers, regenerated with electric heater elements in pressurised vessels...works well...

PekkaNF:
That is very inspiratonal project!

I have a small amount of Silica Gel (probably cheapest and corse, because it is ised to keep boat interior dry during winter) and I have been thinking something similar last two years. Small pack of it is on my work bench as a reminder....but you have solved the pressure vessel nicely. I have been looking for big/least partly transparent normal water separator for modification and I even had a sintered silencer for filter....but you actually made it.

Very good idea and execution.

What is the next step? Coalescing filter to produce air bearing quality air?
