Abstract
The performance of a simple counter-current adsorber based on the endless belt concept has been studied for vapor phase operation, using as a model system the adsorption of CO2 from N2 on a silicalite adsorbent. For this system the isotherm is essentially linear. The steady-state performance can be represented either by the Kremser equation or on a McCabe-Thiele operating diagram. The system is equivalent to 3–8 theoretical stages, depending on to the flow conditions, and both the steady-state and transient behavior are reasonably well predicted by this model. Under properly selected operating conditions it is possible to obtain a reduction in the CO2 concentration by a factor of 100.
