Hi colleagues!!!

I'm using Aspen Plus to simulate a Reactive Distillation (RD) column for my thesis. I have some examples but I still need to know a few things because this is my first time using this software.

I'm synthesizing n-butyl acetate via Reactive Distillation (Acetic Acid + n-butanol produces n-butyl acetate + water) so the main product is the esther and I'm using RadFrac right now and apparently the unit called DECANT2 has a decanter and I need one to separate the organic phase from the aqueous phase in order to obtain the esther. Does the DECANT2 have a decanter?? or do I need to add one?? and what's the deal with the Valid Phases: Vapor-Liquid-FreeWater?? do I need to use this phase instead of just using Vapor-Liquid so I can use the decanter??

I don't have anyone else to ask so please help me!!!! If you have a more specific example and you think it might be hepful, please give me the link so I can download it.

Thank you so much in advance!!
