$5\mathrm{.}10.-$ It is necessary to calculate the diameter at the base of a distillation column that separates ethylene glycol $($EG$)$ and

diethylene glycol $($DEG$).$ The vapor and liquid flows in this area of $$the tower are $764$ kmol$/$h and $968$ kmol$/$h$,$

respectively. The bottom product has a composition of $98$ mol$\%$ DEG and $2$ mol$\%$ EG$.$ The spine

operates at $1$ bar and will use a $3"$ Intalox ceramic seat filler with a packing factor of $22$ ft$-1$

$.$ the fall

The maximum allowable pressure is $1\mathrm{.}5$ pumps of water per foot at water level. Obtain:

a$)$ The allowable speed of the steam, in m$/$s

b$)$ The diameter of the column, in m$.$

c$)$ The liquid load, in m$3$

$/($h m$2$

$)$

d$)$ Comment on the results obtained: Is the selected column type appropriate? it is appropriate

The size of the filling chosen? Please reply.

$-$ Temperature: $243\mathrm{.}8$C

$-$ Pressure: $1$ bar

$-$ Molecular weights: $103\mathrm{.}1$ kg$/$kmol $($vapor$)$; $105\mathrm{.}2($liquid$)$

$-$ Densities: $2,455$ kg$/$m$3$

$($steam$)$; $932\mathrm{.}6$kg$/$m$3$

$($liquid$)$

$-$ Surface tension: $26\mathrm{.}65$ dynes$/$cm

$-$ Kinematic viscosity: $3,526$ cSt $($vapor$)$; $0\mathrm{.}1647$ cSt $($liquid$).$
