Acetone is produced mainly by the cumene hydroperoxide process, although it can also be obtained by the isopropyl alcohol (IPA) dehydrogenation route. The present work aims to simulate and conceptually design a proposed acetone production process via catalytic dehydrogenation of IPA using the ChemCAD® simulator. The temperature, pressure, mass flow rate, and vapour fraction of the main process streams were obtained, and several key operating parameters for the four shell-and-tube heat exchangers and the two distillation columns were also calculated through the simulation. Liquid acetone is obtained at the top stream of the acetone column with a flow rate of 3,123.04 kg/h and a purity of 99.70%.
