The steady state economic optimization to obtain the most economical design of a double feed
ideal reactive distillation (RD) column is demonstrated. Methyl acetate production process was
investigated to find an optimum number of rectifying trays, reactive tray and stripping tray and
also the optimum location for two feed trays that minimize the total annual cost (TAC). Once the
column configuration is specified, we are left with 2 degrees of freedom where reflux ratio and
reboiler duty are used to meet the specifications (xMeAc= 97 mol% , xH2O= 97 mol%). After the
dominant design variables are identified, a systematic design procedure can be devised for the
column. The simulation was carried out using Aspen Plus with the RadFrac module provided with
Fortran subroutines for the reaction rate.
