Question #93143

Liquid methanol is fed to a space heater at a rate of 12.0 L/h and burned with excess air. The product gas is analyzed and the following dry-basis mole percentages are determined: CH3OH = 0.45%, CO2 = 9.03% and CO = 1.81%, density of methanol = 0.792 g/mL

7.1 Write the equations for the process

7.2 Calculate the feed flowrate in mol/h

7.3 Draw and label the material flow diagram which describes the process.

7.4 Calculate the fractional conversion of methanol and the mole fraction of water in the product gas. (Hint- atom balances may assist)

7.5 Calculate the percentage excess air.

7.6 Suppose the combustion products are released directly into a room. List 2 potential problems and 2 measures to control or mitigate these problems.
