adsorption isotherms <strong>of</strong> five typical solvents as a function <strong>of</strong> the solvent concentrations in<br />

the gas stream. It is clear that different solvents are adsorbed at different rates according to<br />

the intensity <strong>of</strong> the interacting forces between solvent and activated carbon.<br />

Physical-chemical properties <strong>of</strong> three typical activated carbons used in solvent recovery<br />

appear in Table 22.1.9.<br />
