Using Aspen Plus Program to Design and Enable the Cracking of Acetone and the Manufacture of Highly Pure Acetic Anhydride

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.
Aspen Plus ni moja ya viungo vya msingi vya acetone, ambayo hutumiwa kwa kuunda na kuunda anisodiamu ya asidi ya asidi (AAS), ambayo ni pamoja na asidi ya asidi ya asidi (AAS), na asidi ya asidi ya asidi (AAS), ambayo hutumiwa kwa kuunda na kuunda asidi ya asidi (AAS) na kutengeneza asidi ya asidi (AAS) na methane (CH). Chitin inayotokezwa lazima kisha iingilie pamoja na asidi ya asidi ili kutokeza anhydride ya asidi. Mfumo huu unajumuisha kichocheo cha mtiririko wa kuziba (PFR), ambapo acetone inashindwa kwanza katika chitin na methane katika joto la 762 ° C na 1.8 atm, na safu ya RadFrac (RECTF) ambayo hutenganisha chitin kutoka kwa methane na acetone iliyobaki. Chitin na asidi acetic athari, ambayo husababisha kizazi cha anhydride acetic, ni kisha iliendelea kwa kuongeza daima stirred tank reactor. Kisha muundo huo unathaminiwa kwa kutumia programu ya V9 Aspen Plus.
