Re: [PSUBS-MAILIST] open source scrubber design

[Jon Wallace <jonw@psubs.org>]

Alec's test results will be very interesting to follow.  These canister 
units, if I understand the way Alec intends to use it, are a radial 
design.  One of the potential problems I see is that there is only 1-1.5 
inches of material in the void between the canister walls which makes me 
question whether that will provide adequate "dwell time" for the CO2 to 
pass over the material and be absorbed efficiently.  It will also be 
interesting to hear from Alec how difficult the units are to pack with 
material.

Alec, depending upon your results I would also look a modifying the can 
somewhat by adding a center tube, maybe 1 inch in diameter through the 
axial center of the can (like this 
http://www.flickr.com/photos/billreals/2966584447/ ).  Add sodasorb into 
the interior (and between the canister walls if you want) and feed the 
air flow through the center tube via a centrifugal fan.  This would 
allow more dwell time through more material.
