Hi I am working on a school research project, trying to simulate something similar to Sunoco/UOP phenol plant. Now they have this dehydrator whereby a stream that contains some water, cumene, AMS, a lot of phenol and acetone and minor other stuff passes through it. For the dehydrator section, they use only MP steam and cooling water to cool the stream to achieve dehydration. (Pls refer to the attached screenshot)

 

I understand phenol has a higher bp and acetone has a lower bp than water, and water has a bp that kind of stucks in the middle. Hence I don't understand why water can be removed from cooling with phenol or acetone preserved in the main stream.

 

Thanks for the help!
