By applying the rule-of-thumb discussed in Section 1.6.3.2, the working capacity may be estimated at 50% of the equilibrium capacity, as follows: wc  0.5wc (max)  0.167 lbVOC / lbCarbon wc(max) = Equilibrium capacity at the adsorber inlet (lb VOC/lb carbon) Carbon Requirement: When operating, the adsorber will have two beds adsorbing and one bed regenerating/in stand-by at all times. Using equation 1.12 we can estimate the amount of the desorption time (ΘD): where where ND = NA = ΘA = ΘD = Number of desorbing beds Number of adsorbing beds Total time for adsorption (hours) Total time needed for bed regeneration, drying, and cooling (hours) N 1 D A D 12hours 6hours NA 2 Because the stated design desorption time of 5 hours is less than the 6 hours needed for bed regeneration, the proposed bed configuration is feasible.
