Abstract
| - Activated carbon adsorbers are used to recover dilute solventvapors from process streams beforethey are vented to the atmosphere. Determining the workingcapacity of an adsorber, orestimating the amount of adsorbent needed for an application, reliesupon either crude rules ofthumb or rigorous modeling of the process. As an alternative, anapproximate solution to thematerial and energy balances for steaming a fixed bed adsorber isproposed. The new designmethod reduces the mathematics of modeling steam regeneration frommultivariate calculus toalgebra. It also permits evaluating vendors' claims of superiorperformance for their adsorbents,optimizing steam consumption for regeneration, and evaluating differentregeneration conditions.Predicted working capacities are compared to experimentalresults.
