Re: [PSUBS-MAILIST] CO2 scrubber
Chemical regeneration of carbonate to hydroxide is pretty
straightforward: "burn" in a kiln to liberate CO2, leaving the oxide,
then slake the oxide with water to form the hydroxide.
Problem is that the physical form of the compound will change, and it's
important to our application that the form be uniform, dust-free and
non-caking.

Anything can be done with power to burn. CO2 scrubbing is done with water
at elevated pressures in biogas treatment on large scales using tower
fillers such as the rings. Generally done more effectively at just over
1000 psi.
Also CO2 levels from 20-30% scrubbing down to 3-5% from memory. Not viable
with p-subs. Why aren't the sofnolimes of the world out of business?
Because it is the best system. More to the point is how can we regenerate
the 'limes in a safe and effective way. Now that is a better thread to
follow. At $15 per kilo it would be nice to stick it in the oven, or
whatever it takes for 10 minutes to bring it back. Hugh
