Chemical Engineering Question. Please Help.
Methanol is catalytically oxidized to form formaldehyde (CH2O) in the following reaction. Unfortunately under the conditions used to produce formaldehyde at a profitable rate, a significant portion of the formaldehyde reacts with the oxygen to produce carbon monoxide and water.
CH3OH + ½ O2 -> CH2O + H2O
CH2O + ½ O2 -> CO + H2O
Fresh air (79 mol% N2) is supplied in 100.% excess of the methanol needed to produce formaldehyde. Your reactor has a 90.% methanol conversion, and you get a 65% yield of formaldehyde.
Using atomic species balances method:
a) Draw and completely label the flow chart.
b) Do a Degree of Freedom analysis for the system â be sure to clearly indicate what unknowns and equations are being counted.
c) Write out the necessary balances and other equations and determine the conversion of oxygen.
