The exhaust gas of the combustion of liquid methanol with excess air is analysed and the following dry-basis mole percentages are determined: ch3oh 0.52%; co2 - 12 %; and co 1.55%. liquid methanol enters a burner at rate of 15 l min1 and density of 792 kg m3 write the chemical reaction equations of combustion [1 mark] (a) (b) draw the flow diagram of the burner showing all streams and their components. [2 marks] (c) calculate: the theoretical oxygen and air needed (i) (ii) the molar flow rate of the dry exhaust (ii) the flow rate of water in the exhaust (iv) the flue gas composition on a dry basis and the mole fraction of water [3 marks] [4 marks] [2 marks] [4 marks] 1 mark] 1 mark] (v) (vi) the percentage excess air used. the fractional conversion of methanol. (d) how would you process the exhaust gases of the combustion if the process is used for heating of a house?
