Question

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, $\log_{10} [P_{sat} (T(^{\circ}C), in mmHg)] = 7.87863 - \frac{1473.11}{(T + 230.0)}$ 1 atm=760 mmHg

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.

c) What model would you use to determine how much air is in the liquid methanol? Explain your
answer.
Note: for methanol, log10 [Psat (T(^∘C), in mmHg)] = 7.87863 - (1473.11)/((T + 230.0))
1 atm=760 mmHg
