I’m encountering some problems while studying Aspen adsorption, and I hope those with more experience can offer some guidance. I’m extremely grateful; thank you very much for taking the time to help me. (The attachment contains a clear description of the problems, along with the relevant source files.) The first question: Pressure setting is a very important issue. For a single-layer adsorbent bed, once P1 and TD1 are determined, the pressure setting is complete. How should one determine the value of TD1? Additionally, is the method used to calculate P1 correct? The first question: Pressure setting is a very important issue. For a single-layer adsorption bed, once P1 and TD1 are determined, the pressure setting is complete. How to determine the pressure of TD1? Is the analysis process for P1 correct? Second question: How to determine the value of Cv? I have consulted a large amount of literature; I already know that Cv = Flow_prod/(Pfeed – Pprod). However, I am confused about how to determine the value of Cv. I want to know, through this example, how to calculate VD1 and VW1.Cv. Please provide the details and steps involved in the calculation process – this is very important to me. Second question: How to design Cv? I have already reviewed plenty of literature, and I know that Cv = Flow_prod/(Pfeed – Pprod). However, the design of CV confuses me. I would like to know how to calculate VD1.Cv and VW1.Cv using this example; it is very important for me to have the details and steps of the calculation process.
