Loop Convergence With Different Water Content In Two Different Loop

Loop Convergence With Different Water Content In Two Different Loop

Loop Convergence With Different Water Content In Two Different Loop

(OP)
I am using Aspen plus to simulate a process where we have to separate the product and undesired product in Separation 1 column and Separation 2 column equipment respectively.


Both of the separation columns use water, so they have some amount in their respective outlet stream based on the equilibrium of the top stage of the respective column.
So that causes different water concertation in streams 101 and 103.

Now in order for two recycle streams to converge I need to have the water concentration balanced. How can I, in this situation? Purge? But that causing a large amount to be purged.
Would appreciate any advice.
