Ethanol is produced commercially by the hydration of ethylene
C2H4(g) + H2O(v) → C2H5OH (v)
Some of the product is converted to diethyl ether in the undesired side reaction
2C2H5OH(v) ↔(C2H5)2O(v) + H2O(v)
The combined feed to the reactor contains 53.7mole% C2H4, 36.7% H2O and balance nitrogen
which enters the reactor at 310°C. The reactor operates isothermally at 310°C. An ethylene
conversion of 5% is achieved, and the yield of ethanol (moles ethanol produced/mole ethylene
consumed) is 0.9. Calculate the reactor heating or cooling requirement in kJ/mol feed.
