Methyl Acetate Hydrolysis for Production of Acetic Acid and Methanol

The purpose of this paper is to introduce a new process for hydrolysis of methyl acetate (M.A). Methyl acetate is produced as a by-product in chemical plants such as, polyvinyl alcohol and terephthalic acid. Hydrolysis of M.A results in producing the value added products i.e. acetic acid and methanol. The process eliminates the needs to a complicated design as well as high investment and operating costs in comparison to the reactive distillation process. In fact in this experimental study the fixed bed reactor is used as the reflux drum of the distillation column. In the present research, the experiments have been conducted in an experimental set up and different operating parameters such as the mole ratio of water to M.A. in the feed (RJ, reactor temperature (Tr) and volumetric flow rate of feed to catalyst volume (LHSV) have been investigated. The experimental results are in accordance with the simulated process results obtained by Hysys.
