Abstract
A separation system for a methyl acetate hydrolysis is provided. The separation system comprises a reactive distillation system, a reflux system, a first separation system and a second separation. The reactive distillation system allows the hydrolysis of a methyl acetate solution to generate a first mixture and a second mixture. The reflux system is packed with a heterogeneous catalyst and coupled to the reactive distillation system, which refluxes the first mixture to the reactive distillation system. The first separation system is coupled to the reactive distillation system, which directs the second mixture thereinto so as to isolate an acetic acid and a third mixture therefrom. The second separation system is coupled to the first separation system, which directs the third mixture thereintio so as to separate a methanol therefrom. The methyl acetate feeding system is coupled to, one of the reactive distillation system and the reflux system, which feeds the methyl acetate solution thereinto.
