Simulation study on the feeding status of the light component removal column in the carbonylation process for the preparation of acetic anhydride
The parameters including reflux ratio,column diameter,material balance and heating load of the light component removal column are simulated under the vapor and liquid feeding status,using Aspen Plus software.The simulation results show that the cooling load and heating load under the vapor feeding status are 74.8% and 38.3% of those under the liquid feeding status,respectively.
