Extracted text: Formaldehyde (HCHO) can be formed by oxidation of methane. The oxidation process takes place by air (71% mole N2, 21 mole % 02) which is provided 20% excess. Methane is provided at the rate of 60 mol/s. CH4 + O -- --> HCHO + H20 CH4 +2 02 - CO2 +2H20 i) Sketch the flow chart and perform the material balance ii) Calculate the fractional conversion of methane if there are 15mol/s methane at product. iii) Calculate the fractional yield of formaldehyde if the produced formaldehyde amount is 25 mol/s.
