Residual Protective Life of Carbon Beds.
Abstract
Retention times of weakly sorbed (probe) gases were used as a measure of the residual sorption capacity for strongly sorbed dimethyl methylphosphonate (DMMP) on ASC carbon. At room temperature, with space time of 3 sec and 12 cm/sec superficial velocity of He carrier gas, the retention time of carbon dioxide decreased from 4 to 0.3 min as the fractional length of the bed saturated with DMMP increased from zero to unity. Under different conditions the retention time of ethane decreased from 1.6 to 0.03 min as a mixture of He and DMMP vapors passed into the column. The retention times of ethane and carbon dioxide as well as other probe gases were measured as a function of He flow rate and DMMP loading.
