Simulation of absorption and adsorption by ASPEN
Thread Content
I would like to use ASPEN to simulate the absorption of acidic gases by dilute alkaline solutions. How would you choose the property methods and models? If chemical absorption and physical dissolution occur, is it necessary to make special arrangements? If one wants to simulate the gas-solid adsorption of gases by an adsorbent, how should one choose and configure the models and material properties? How can one use ASPEN to determine the solubility of gases in a solution at a certain temperature and pressure? I’m a beginner with many questions; I hope everyone can help.
An old question; no one has answered it yet, so I’m raising it myself. I’ve been doing simulations of the alkaline solution absorption of CO2 lately, but there are always problems. I checked relevant posts on forums as well, but couldn’t figure out what’s going on. It mainly concerns how to specify the electrolyte components in the component table – for example, is it necessary to include NaOH as well as Na+ and OH- in the component list? When selecting electrolyte components, should all of them be chosen or only the ions? When entering a chemical reaction, should an ionic equation or a molecular equation be used? I hope experts can help answer this; thank you very much
