for a two phase separator the methodology of doing the mass balance would be
1. For a specified key component overhead recovery, and P and T
2. Calculate,K and relative volatility at T
3. Evaluate for each component k using
Sk= (relative volatility of k) x (key component overhead recovery)
1+ (relative volatility of k-1)(key component overhead recovery)
4. Reconstruct a mass balance and calculate mole fractions:
vapor flowrate= Sk x fk fk - component feed flowrate
liquid flowrate =(1-Sk) fk
i guess we cannot use this formula to get the 3 phase separator mass balance, how is the mass balance for the three phase separator done then?

Hello valentino,
There are some good reference books on this topic. Unfortunately, I do not know of only one method to do this (each method depends on the design criteria).
If you have access to a library, you may want to look up the details in the following copyrighted book:
GPSA Engineering Data Book Vol.1 Section 7
I hope this helps,
Eugene
