Separation is a burdensome process as the second law of thermodynamics does not favor it. Since it requires relatively large amoun of energy, the separation process generally contribute 40-70% of the total cost of production. Therefore, not olny production quality but also economic feasibility is required in the separation process. Adsorption refers to the spontaneous accumulation of adsorbate (gas or liquid) on a solid (adsorbent) surface. Due to mild operation conditions, the adsorption process has the advantage of low energy consumption. Adsorptive separation processes such as PSA (pressure swing adsorption) and SMB (simulated moving bed) have been widely used in the separation of various mixtures: H2 purification, fuel gas upgrading, CO2 capture, separation of xylene isomers and so on. This presentation introduces studies on adsorbent modification, analysis of adsorption behavior, and process design and optimization to improve the efficiency of the adsorption processes. |
