effect of feed tray location in distillation

Additionally you still need to use the Gilliland and subsequently the Kirkbride method to determine the feed tray location. Just briefly, 1. Fenske method estimates the minimum number of stages (at total reflux). 2. Underwood method estimates minimum reflux ratio. 3. Gilliland method estimates the number of theoretical stages required. 4.

How does feed location affect distillation? Placing the feed tray too high in the tower can result in excessive condenser duty (reflux ratio) to meet distillate product specification. Too low a feed

01/09/2005 · First we fix the N F, A at the bottom of the reactive zone and change the feed location of the B component from top to bottom. At constant volatilities systems, the feed

Moreover, the feed temperature and feed tray location of the HP column were presented, reflecting a major effect on the DMC process plant. 3.1.

or feed tray in the distillation column is the concern of this study • In general, the effects of changing feed plate location.

What are the effects of feed tray location in Distillation column ? - We know that we can find feed tray location by McCabe Thiele Method but this method is use only for binary component. So, for

15/10/  · The impact of altering feed tray locations (for the purpose of saving energy) on the controllability of double feed reactive distillation (RD) columns is evaluated for two case

01/11/1993 · The MINLP minimizes the total annual cost subject to a rigorous tray-by-tray model. The solution of this MINLP yields the optimal number of trays, the optimal feed rates, and the optimal feed tray locations. The liquid holdup per tray, the reflux ratio, and the temperature and composition profiles within the column are optimized as well.

01/02/  · The optimum feed tray location is tray 3 from top (N=3 and M=14 including reboiler). Table 4. Condenser and reboiler duty vs feed tray location . Figure 2. Condenser and reboiler duties as a function of feed tray location . The column temperature profiles as a function of feed tray location are shown in Figure 3. The optimum feed tray location

Generally speaking, if the feed enters in higher tray the light components concentrations in overhead will be increased and in bottom outlet
