Re: [PSUBS-MAILIST] oxygen use

Thanks Jon, great stuff.
You mention using clear canisters and an indicating chemical in the scrubber 
design.
Is this a separate chemical you can add to the absorbent? I have 20kg of 
Sofnalime
which is non indicating and would like to change that.
Also I calculated that at 1/2 a liter of O2 consumption a scrubber would 
last 200 minutes per
kg of absorbent.  I seem to remember that ABS recommended 3 days air supply 
on a one man sub.
Does this mean they expect me to take down 20kg of absorbent?
Thanks Alan
