Adding the Recycles
Make-up streams are necessary to compensate for the losses of Acetone
and Water in the process product streams. To calculate the exact
amount that is lost in the products, Balance operations are used. These
are not real operations but only mathematical ways of obtaining the
make-up values.
A Mole Balance operation will be used to create two streams (Rec Acet
and Rec Water) with the same flowrates and compositions as the tower
product streams Benzene and CycloC6, respectively.
These streams are then sent to a Component Splitter and split into two
streams: one containing the product and the other containing traces of
the lost solvent.
The streams containing the lost solvents are the make-up streams
which will be mixed with the recycled streams from the solvent
Recovery Tower.
