HOMEWORK $2$

An ammonia gas stream from a reactor contains $25\%$ ammonia and the rest inert gas. The

total flow is $1000$kgmo$\frac{l}{h}$ to an absorption tower at $30C$ and $1$atm where water containing

$0\mathrm{.}5\%$ ammonia is scrubbing liquid. It is desired to reduce gas to an outlet concentration of $2\%$

ammonia. What is the minimum liquid flow? Using $1\mathrm{.}5$ times the minimum, plot the operating

line. Find the number of the theoretical trays.
