Please use extent of reaction on the process: Ethanol can be produced by the direct hydration of ethylene with H2PO4 at 300oC and 6.8 MPa according to the reaction: CH2=CH2 + H2O → C2H5OH The following side reaction also occurs during the process: CH2=CH2 + H2O → C2H4O + H2 The yield of ethanol is 92% and the single-pass conversion is 13%. The molar ratio of ethylene to water in the feed to the reactor is 1:0.6. Unreacted ethylene is separated from the reactor effluent and recirculated. a) How much ethylene and water are required to produce 100 kmol of ethanol?(fresh feed) b) How much ethylene is recycled for the production rate?

Question

Please use extent of reaction on the process:

Ethanol can be produced by the direct hydration of ethylene with H2PO4 at 300oC and 6.8 MPa
according to the reaction:

CH2=CH2 + H2O → C2H5OH
The following side reaction also occurs during the process:
CH2=CH2 + H2O → C2H4O + H2

The yield of ethanol is 92% and the single-pass conversion is 13%. The molar ratio of ethylene to
water in the feed to the reactor is 1:0.6. Unreacted ethylene is separated from the reactor effluent
and recirculated.
a) How much ethylene and water are required to produce 100 kmol of ethanol?(fresh feed)
b) How much ethylene is recycled for the production rate?
