Even though the RD column with a separation unit (Figure 2) represents process integration and
intensification compared to the conventional set-up (Figure 1), there is still a place for improvement such
as the reduction of the large flow of the recycled stream to the decanter or reduction of equipment number.
As the reaction in the RD process has overcome the distillation boundary, it is possible to remove the
decanter and to solve azeotropic mixture regeneration via distillation. Also, the ethanol-water mixture
from the RD column (W11 in Figure 2) can be easily separated into pure water (high boiling point) and
ethanol-water mixture at high ethanol concentrations. Therefore, the flowsheet of the RD column with
a separation unit (Figure 2) was modified: C2 column is integrated into the bottom part of the RD
column; decanter and heat exchangers EX1 and EX2 are removed; C1 column condenser is removed
and overheated vapors from C1 are recirculated back to the RD column (Figure 3). Thus, the process
scheme in Figure 3 contains two columns and three heat exchangers less than the process scheme
shown in Figure 2
