  Edwards, John C.
• Description:
  The Bureau of Mines developed a mathematical model for analysis of the impact of scrubber bed length, porosity, and gas flow rate on the absorption of co2 in a breathing apparatus. The model accounts for the decrease in available absorbent through chemical conversion. The predicted efflux of co2 from a canister containing lioh compared favorably with measured values reported elsewhere. It was determined from a computational study that the time for breakthrough of co2 at a prescribed level is nearly directly proportional to bed length and inversely proportional to gas flow and porosity.
