Methanol evapora$$on and combus$$on $$ MB

Methanol is burned as a fuel in device that uses evaporation to regulate the air to fuel ratio.

In the first part of the process, dry air is bubbled through a liquid methanol evaporator maintained

at $20$o

C$.$ Enough liquid methanol is fed to the evaporator to replace that lost by evaporation. The

methanol leaving in their air stream has $95\%$ relative saturation. The air and methanol is then fed to

a combustor at $1$ atm pressure.

Start by preparing a block flow diagram. Without doing any calculations, explain what calculations

you will do$,$ in what order. What components are you going to need?

Assuming complete combustion, calculate the molar composition of the combustor exhaust gas.

$($ answer : nitrogen mole fraction $=0\mathrm{.}654$
