5.2 Production of Acetic Anhydride in PFR on HYSYS V8.8 • Link: http://processhysysengineer.blogspot.... • Book: Computer Methods in Chemical Engineering by Nayef Ghasem • Chapter: 5 • Example: 5.2 • Pure acetone is fed into an adiabatic PFR at a mass flow rate of 7.85 kg/h. The • inlet temperature and pressure of the feed stream is 760°C and 162 kPa (1.6 atm), • respectively. In a vapor-phase reaction, acetone (CH3COCH3) is cracked to ketene • (CH2CO) and methane (CH4). The following reaction takes place: • CH3 3 COCH ( ) A → CH2CO( ) B + CH4( ) C • The reaction is in first-order with respect to acetone and the specific reaction • rate constant can be expressed by • A=8.2e14 • E= 2.845e5 • Calculate the conversion achieved using a reactor volume of 5 m3. • • 5.3: • 5.3 Packed-Bed Reactors on HYSYS V8.8
