Abstract : The effects of CO2 absorbent particle size at 1 atmosphere pressure and the effect of pressure for a single particle size were investigated using standardized methods for CO2 absorption efficiency. The study covered particles between 4 and 60 mesh size. Testing for pressure effects included variations in gas linear velocity and moisture content at simulated pressures between 1 and 32 atmospheres. There was a tendency for pressure to increase efficiency at low linear velocities and decrease efficiency at high linear velocities for a saturated carrier gas. For a dry carrier gas, increased pressure decreased efficiency for all linear velocities. Decreasing particle size increased absorbent efficiency at the cost of increasing pressure differential across the canister.
