Simulation And Optimum Design On The Column For The Production Of Ethyl Acetate

Ethyl Acetate is an important chemical product ,the main way at home is to synthesize it via esterification of acetic Acid (HAc)with Ethanol (EtOH) using sulphuric acid as homogeneous catalyst.In this paper,a completely new RD system has been modelled and an improvment was made to the present technics by introducing an recycled stream ,rich in HAc and H₂SO₄, from the bottom of the RD column . During the simulation,The kinetics data , Murphree stage efficiency and NRTL model parameter set for caculating of liquid activity coeffecients were rectified basing on the industrial datas provided by the WuJing factory. The results agree very well with the experimental data. The optimum operating condition of the new system will also be studied.The result indicated that the RD system is available with 35% more product and much higher total conversion of 99.83% comparing with 91.43% previously. Above all,it can minimize the total cost of the overall system.
