Theoretical Analysis Dilute Systems with One Adsorbable Component

THEORETICAL ANALYSIS DILUTE SYSTEMS WITH ONE ADSORBABLE COMPONENT 

There is complete formal analogy between continuous countercurrent adsorption and other continuous countercurrent operations such as distillation or gas absorption. Such processes are normally operated at steady state and, for an isothermal system containing only a single adsorbable species, the analysis is straightforward. 

Assuming a linear rate expression and a linear equilibrium relationship, we have, at steady state, 

The adsorbed and fluid phase concentrations at the column outlet are related by an overall mass balance
