There are is no need for Kort nozzles, alcohol (not good in a closed
atmosphere), condensation traps, etc…just keep it simple like a scrubber.
There are two formats for passing gas through a bed: axial flow and radial
flow. Axial flow is simpler with a fan at one end of a tube blowing
thought a screen to restrain your media (moisture and/or CO2), your
media, another screen on the other end, and a spring or some means to put
slight pressure on the media (this minimizes ‘channeling’…shortcuts
through the media that severely reduces its effectiveness). In a radial
flow scrubber the gas is forced down a perforated center tube, gas passes
outward through the media, and then through an outer larger perforated tube.
There also has to be some means to maintain some pressure on the media to
minimize channeling. The radial flow scrubber while more complex is the
more effective design due to less resistance of gas flow caused by a shorter
path and in a CO2 scrubber better heat balance to maintain the
chemical reaction. Moisture absorption can be included in a CO2
scrubber by including a layer of moisture absorbent chemical and increasing the
flow path to account for the added material. Care must be taken with all
of the materials mentioned in this thread to minimize chemical dust that will
get in the respiratory system and cause distress. Most of the CO2
absorbent materials do not play well with water and can be even explosive
(LiOH). Respectfully, Jay K.
