Suppose you work for a specific consulting firm that specializes in designing propanol (C$_3$H$_8$O, MW = 60.1 g/mol) absorption columns. You are given a project to design a propanol scrubber operating at 17°C and 760 mmHg with 1.5 inch ceramic Intalox saddles. The incoming gas stream is saturated with water, has an 8 mol% propanol and 92% air mix. The mix is scrubbed with water to recover 95% of the propanol. The incoming water stream is pure, with additional data given below.
$S_{C_3H_8O, Air} = 0.69$
$S_{C_3H_8O, H_2O} = 947$
$\frac{L_M}{G_M} = 3.2$
$P^*_{C_3H_8O} = 132 mmHg$
$G_y = 1160 \frac{lb}{ft^2 \cdot hr}$
$D_{C_3H_8O, H_2O} = 1.14 \times 10^{-5} \frac{cm^2}{s}$
$x_{a, C_3H_8} = 0$
$x_{b, C_3H_8} = $
$y_{a, C_3H_8} = $
$y_{a, H_2O} = $
1 1/2" Ceramic Intalox Saddles
$y_{b, C_3H_8} = 0.08$
$y_{b, AIR} = 0.92$
A. Determine the height of the column. Assume the slope of the equilibrium line is constant with a slope of $P^*/P_{atm}$.
B. Calculate/determine the pressure drop at flooding for these 1.5 inch Intalox?
