Using Aspen Plus Program to Design and Enable the Cracking of Acetone and the Manufacture of Highly Pure Acetic Anhydride
Keywords:Aspen Plus, Acetic Anhydride, Ketene, Acetone
In order to convert acetone into acetic anhydride, a system that can break down acetone and decompose it into chitin and methane under specific operating conditions of temperature and pressure is required. The produced chitin must then react with acetic acid to produce acetic anhydride.
This system consists of a plug-flow reactor (PFR), where the acetone is first broken down into chitin and methane at 762 °C and 1.8 atm, and a column of RadFrac (RECTIF), which separates the chitin from the methane and the leftover acetone. The chitin and acetic acid reaction, which results in the generation of acetic anhydride, is then continued by adding a continuously stirred tank reactor. The design is then assessed using the program V9 Aspen Plus.
