The input of this reactor is stream 3 where a mixture of ethanol and water enters at a
temperature of 329.85°C and 1 bar. The output is stream 4 with a mixture of ethanol, water,
acetaldehyde, ethyle acetate, butanol, acetic acid and hydrogen leaving at the same
temperature and pressure.
The reactions;
1. CH3CH2OH ? CH3CHO + H2
2. 2 CH3CH2OH ? CH3COOC2H5 + 2 H2
3. 2 CH3CH2OH ? CH3(CH2)3OH + H2O
4. CH3CH2OH + H2O ? CH3COOH + 2 H2
Ethanol's conversion is assumed to be 62%, and the yields for each reaction is
1. Acetaldehyde 91.77%
2. Ethyl acetate 1.90%
3. Butanol 1.15%
4. Acetic acid 2.00%
The feed enter the reactor 496.26 $\frac{kmol}{hr}$ of ethanol. Since the feed contains only 85 wt.%
ethanol, molar flow rate must be converted back to mass flow rate to determine the required
feed rate in kg/hr.
Calculate the molar composition of product of reactors and extent
($\xi_1, \xi_2, \xi_3, \xi_4$) for each reactions.
