The flow direction of the reactive distillation product is too extreme, how to adjust it?

Reactive distillation simulating the hydrolysis of methyl acetate. As a result, the product methanol almost does not come out from the bottom of the tower. However, in some literature, methanol and acetic acid come out from the bottom of the tower together, as shown in the figure.: Could you please tell me how to adjust the parameters? (The single-pass conversion rate is low. If the tower top discharge is to be recirculated, should the cycle be opened first or should it be optimized first? ) Thanks!

I don't understand what you mean. Don't your diagrams and tables correspond to each other? In the picture, methanol comes out from the top of the tower. Doesn’t it also come out from D on the table? What do you mean by "the methanol product almost never comes out from the bottom of the tower"? Shouldn't it come out from the bottom of the tower in the first place?

1. In your example, do methanol and methy-01 form an azeotrope, which has a lower boiling point than methyl formate?; 2. Whether methanol and acetic acid come out from the bottom of the tower depends not only on the system, but also on the operation, that is, whether the operation you set meets the requirements of the remaining curve.

Solved, modify the operating specifications of the tower (I used the reflux ratio and distillate feed ratio, although I don’t know the principle)
