Question $1$:

An advanced catalytic combustor is to be fed a premixed methanol$/$air gas stream containing $20\%$ excess

air, made by passing the air through a bubble$-$column "saturator" containing liquid methanol. The

stream $($at ambient pressure$)$ gains methanol in the unit and leaves with a methanol vapor composition

in equilibrium with the liquid methanol.

a$)$ If the combustor requires $4$ mole$/$minute of methanol, what will be the molar flowrate of feed air?

b$)$ What temperature do you recommend for the saturator to produce the desired gas composition?

c$)$ What model would you use to determine how much air is in the liquid methanol? Explain your

answer.

Note: for methanol, sat $,$ in $\{$:$mmHg]=7\mathrm{.}87863-\frac{1473\mathrm{.}11}{T+230\mathrm{.}0}$

$1$atm$=760mmHg$
