Regarding the issue of simulated absorption.
Thread Content
I am simulating a section that produces DMC. One of the towers is used to remove methanol from the azeotrope of dimethyl carbonate and methanol. This should be a absorption tower. I read a few articles on the forum regarding absorption, but I’m still unable to carry out the simulation. I also don’t know how to set it up in STEUP. Could you please explain it in detail, or upload an example of a absorption tower simulation for me to refer to? Thank you
Regarding absorption, the ratefrc model for non-equilibrium states is available; there are tutorials on the forum, which I hope will be helpful to you
I think this is a distillation tower. DMC and methanol are an azeotrope; water is added as an azeotrope breaker to disrupt the azeotic composition of DMC and methanol, allowing water and DMC to separate together while methanol separates on its own. For azeotropic distillation, use the Radfrac model. It's crucial to pay attention to the issue of the binary interaction parameter. Hope this is useful to you~~~
What is the principle behind using water as an azeotrope? Could you talk about it?

This is a distillation tower; DMC has an azeotrope with methanol, and water is added to remove methanol. I agree with the view above; the key to simulation lies in the selection of the thermodynamic model.
