Design of an acetic anhydride manufacturing facility, states that one of the key steps is the vapor-phase cracking of acetone to ketene and methane: CH3COCH3   CH2CO + CH4He states further that this reaction is first-order with respect to acetone and that the specific reaction rate can be expressed by ln k = 34.34 – 34.222/T       Where k is in reciprocal seconds and T is in Kelvin. In this design, it is desired to feed 8000 kg of acetone per hour to a tubular reactor. If the reactor is adiabatic, the feed pure acetone, the inlet temperature 1035K, and the pressure 1 62 kPa (1.6 atm), a tubular reactor of what volume is required for 20% conversion?

Example Problem

Cracking in vapor-phase Reaction is first-order with respect to acetone feed 8000 kg of acetone per hour Tubular reactor Reactor is adiabatic feed is pure acetone The inlet temperature 1035K, and the

pressure 162 kPa (1.6 atm), 20% conversion

Data from given problem
