A petrochemical plant in produces formaldehyde (CH2O) industrially by the catalytic oxidation of methanol (CH3OH). The following is the chemical reaction: CH3OH + ½O2 → CH2O + H2O --- (1) Unfortunately, a significant portion of the formaldehyde will react with oxygen to produce CO and H2O. The following is the side reaction: CH2O + ½O2 → CO + H2O --- (2) Assume twice the stoichiometric amount of air needed for oxidation (all chemical reactions) is fed to the reactor. The conversion of methanol is 90% in the reactor. The outlet stream of the reactor was analysed and found to be 150 kg/hr of formaldehyde, 30 kg/hr of CO and other components.

Question
A petrochemical plant in produces formaldehyde (CH2O) industrially by the
catalytic oxidation of methanol (CH3OH). The following is the chemical reaction:
CH3OH + ½O2 → CH2O + H2O --- (1)
Unfortunately, a significant portion of the formaldehyde will react with oxygen to produce CO and H2O.
The following is the side reaction:
CH2O + ½O2 → CO + H2O --- (2)
Assume twice the stoichiometric amount of air needed for oxidation (all chemical reactions) is fed to the reactor. The conversion of methanol is 90% in the reactor. The outlet stream of the reactor was analysed and found to be 150 kg/hr of formaldehyde, 30 kg/hr of CO and other components.
