The course : Separaion processes $($b$)$ Give reasons for each of the following:

$(10$ points$)$

$1-$ The increase in temperature during the gas absorption process should be removed.

$2-$ At minimum liquid to gas flow rates there is no separation.

$3-$ The presence of liquid seal at top & bottom of packed column.

$4-$ The layout of tray in plate column is different in gas absorption process than in distillation.
