Distillation stage calculations are usually performed with ideal stages, The number of ideal stages required for the separation is divided by the overall column efficiency (Sec, 7,1,1) to obtain the required number of trays. In packed towers, the number of stages in the column is multiplied by the HETP ( Height Equivalent of a Theoretical Plate

Consider as a base case, a 10 stage column. The feed is a binary mixture that has a composition of 0.5 mole fraction in terms of the more volatile component, and introduced at stage 5. The steady-state terminal compositions of about 0.65 at the top (stage 1) and 0.1 at the bottom (stage 10) are shown below:

Generally speaking, if the feed enters in higher tray the light components concentrations in overhead will be increased and in bottom outlet will be decreased; heat duty of reboiler and condenser will be increased. If the feed enters in lower tray all mentioned changes will be performed vice versa #3 push121072 Brand New Member Members 9 posts
