I am combusting ethanol. To do this, I put the liquid ethanol into a fine mist, and spray it into the reactor. The reaction proceeds according to the below unbalanced reaction: C₂H6O + O₂ => CO₂ + H₂O The reaction uses pure oxygen and is carried out at high pressures, such that the water formed becomes a liquid. The reaction is conducted at steady state in an advanced reactor, which allows all of the liquids (left over ethanol and water) to leave in one stream, and all of the gases (left over oxygen and carbon dioxide) to leave the reactor in a separate stream. If the molar fraction of ethanol in the liquid stream is 0.10 and the molar fraction of oxygen in the gaseous stream is 0.6, find the fractional conversion of ethanol in the reactor and the fractional excess of oxygen (which is defined as the ratio of the amount of oxygen fed to the reactor to the amount of oxygen which is needed to react all of the ethanol fed to the reactor).

Question
Transcribed Image Text:4. I am combusting ethanol. To do this, I put the liquid ethanol into a fine mist, and spray it into
the reactor. The reaction proceeds according to the below unbalanced reaction:
C₂H6O + O₂ => CO₂ + H₂O
The reaction uses pure oxygen and is carried out at high pressures, such that the water formed
becomes a liquid. The reaction is conducted at steady state in an advanced reactor, which
allows all of the liquids (left over ethanol and water) to leave in one stream, and all of the gases
(left over oxygen and carbon dioxide) to leave the reactor in a separate stream.
If the molar fraction of ethanol in the liquid stream is 0.10 and the molar fraction of oxygen in
the gaseous stream is 0.6, find the fractional conversion of ethanol in the reactor and the
fractional excess of oxygen (which is defined as the ratio of the amount of oxygen fed to the
reactor to the amount of oxygen which is needed to react all of the ethanol fed to the reactor).
