A petrochemical plant in Island C 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.(i) Determine the mass flowrate (kg/hr) of Stream A. (ii) Determine the molar flowrate (kg-moles/hr) of Stream B (iii) Determine the mass flowrate (kg/hr) of water in the outlet stream.
