task 1

The gas-phase reactions

Isobutanol (B) -> Isobutene (IB) + H2O

(CH3)2 CHCH2OH (CH3)2 C = CH2 + H2O

2Methanol Dimethyl ether (DME) + H2O 2CH3OH -->CH3OCH3 + H2O

Isobutanol + Methanol Methylisobutyl ether (MIBE) + H2O

(CH3)2CHCH2OH + CH3OH (CH3)2 CHCH2OCH3 + H2O

21sobutanol --> Diisobutyl ether (DIBE) + H2O

2(CH3)2 CHCH2OH (CH3)2 CHCH2OCH2CH (CH3)2 + H2O

Take place in a continuous reactor operating at steady state. The feed to the reactor consists of N2: 10,000 mol/h, isobutanol (B): 8333 mol/h and methanol (M): 16,667 mol/h. The effluent flow rates are isobutene (IB): 2923

mol/h, dimethyl ether (DME): 3436 mol/h, methyl isobutyl ether (MIBE): 5038 mol/h and diisobutyl ether (DIBE): 22 mol/h.

1. What is the fractional conversion of isobutanol?

2. What is the fractional conversion of methanol?

3. What is the mole fraction of water leaving the reactor?
