Pressure swing adsorption (PSA) has become one of the most prominent carbon capture technologies as a huge amount of attention has been paid to climate issues. The performance of PSA is directly affected by the adsorbent, a fascinating representative of which is the metal-organic framework (MOF). Recently developed MOFs in limelight characterize S-shaped adsorption isotherm that presents the possibility of reduction of energy consumption. However, the numerical issue of S-shaped isotherm makes it difficult to construct the model of not only the isotherm itself bus also the whole process at a rigorous level. In this work, an S-shaped isotherm is suggested and applied to the rigorous model of a PSA process. Moreover, the multicomponent adsorption considering the S-shaped isotherm is addressed by the ideal adsorption solution theory (IAST). The resulting rigorous model of multicomponent PSA can be utilized in the detailed optimization and control of the process |
