How to separate propylene and propane from carbon dioxide, oxygen, nitrogen, etc
Thread Content
As the title suggests, I am encountering problems while simulating the ammoxidation of propylene to produce acrylonitrile. How can the propylene, which is the reactant in this reaction, be separated from waste gases such as carbon dioxide? I hope the experts here can offer some advice
Is absorption needed? Like MDEA or something?
Could the expert be more specific? Thank you
I’m not sure if this will be useful, or whether this process is suitable for your processes. There are many posts on MDEA for CO2 removal, as well as practical application examples. Just do a quick search and you’ll find it.
Can’t we use a distillation tower? I remember that distillation towers can be used
If it is the separation of propylene, propane from carbon dioxide, oxygen, and nitrogen – with no other components present – a single distillation tower is sufficient to handle this task. Of course, processes such as pressure swing adsorption can also be used, but from an industrial perspective, a distillation tower is sufficient; even a distillation section alone is enough, as long as there is a stripping section
