[PSUBS-MAILIST] CO2 Sorb

[Cliff Redus via Personal_Submersibles]

Scott, ABS  uses  a value of 0.115 lbm CO2  generated per hour per
occupant.  Sotasorb HP specification says it can absorb 41% CO2 by weight.
This comes out to 3.56 Persons-hours per pound of SodaSorb HP which is
close the number Alec posted.  ABS rules call for full life support for 72
hours plus normal duty time.  If you assume normal duty time is 8 hours,
then the life support system would need to last for 80 hours.  For one
person this would give 22.5 lbs of SodaSorbHP and for two, 45 lbs for this
duration.

Actual consumption rate is dependent on a lot of parameters, such as
temperature, humidly, mass of occupants and design of scrubber to mention
just a few.
