maximum absorption capacity. Once water is fully saturated with both species, the desorbing gases cannot be absorbed into the liquid and can be easily separated from the desorption sink using a gas separator without additional energy input. This rationale is based on the assumption that the amount of carbonic acid produced as a result of reaction of CO2 with water is small and does not react with the walls of the system components and the microchannel adsorbent layer. Another important underlying assumption in modeling desorption with saturated water is non-interaction of the absorbed gas in water and the adsorbent. This assumption can be justified by considering the direction of gas flow, which is from adsorbent to the microchannel and remains so at the beginning of the desorption stage. Additionally, for adsorbents like silicalite, the adsorption isotherms at high partial pressures are more sensitive to temperature than partial pressure (Palomino et al., 2009). Hence, in the later stages of desorption, even if fully saturated water reaches the adsorbent through void spaces and creates a scenario in which absorbed gases contribute to the partial pressure for adsorption, its effect on adsorption capacity is minimal. With water recirculation, as shown in Figure 3.2(b), gas recovery is estimated to initiate from the desorption sink only after 4000 s or after 20 cycles. This leads to an important simplification in process modeling: if fully saturated hot water is used for desorption, the operation of a real cycle is analogous to a case without absorption of gases and near-complete recovery of gases lost to the HTF stream is possible. 73PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
