2. Formaldehyde (FA) is produced by oxidation of Methanol (CH3OH) in a fixed bed reactor according to the reaction. CH;OH (g) + 1/202(g) → HCHO(g)+H2O(g) All of the HCHO (FA) is removed in condenser. Purge gas is 78 % N2 and 60 % single pass conversion of methanol takes place in reactor. Fresh feed is the mixture of air and methanol. a) Calculate the molar flow rate and composition of the purge stream b) Find the molar flow rate of recycle stream and each chemical compound in stream F. R 78 % N2 Air, 94 mol/h O2: 0.21 N2: 0.79 F Reactor Methanol, 6 mol/h Formaldhyde, 4.8 mol/h
