I am designing a decanter to separate the effluent stream of a reactor which consists of two immiscible liquid phases.

 

I understand the procedure of sizing a decanter, however I am rather confused concerning certain matters:

 

1- How do I tell which phase is the dispersed and which phase the continuous?

2-Unless i know the particle diameter of the dispersed phase , i assume it is 150 micro m?

3- The design procedure gives no indication of the % separation achieved..?

I assume this is a class project assignment. Since it won't ever be used, you should make the necessary assumptions and proceed. Decanter design procedure is such that you don't need to know the continuous phase. But it is usually the phase with the larger flow. When you finish your work, you can check it with software on my website. Just Google my name to find it.

So I can proceed with the design , assuming the particle D and 90% separation achieved for example?

 

Thanks for the quick response. I am sure that checking my solution with the software will prove more than useful.
