2022. 5. 9. · Step by step procedure to determine the optimum location of feed tray.

Subject 103 - Optimum feed tray location in a fractionation tower: The column is simulated with 30 theoretical trays and the feed tray is initially set to #20. Start from a converged final

trays, and the goal is to select the optimal feed tray location. Figure 1 shows that a superstructure that can be postulated is one where simply the feed is 

1997. 2. 7. · When analyzing existing distillation systems, the actual feed entry point may not be at the optimum (the tray where the operating lines intersect). In this case, the tray stepping should switch from the rectifying line to the operating line at the actual feed tray location. An example of McCabe-Thiele analysis has been prepared.

Kirkbride s method is used to find the optimal feed tray location Np. The lower right graph in Figure 6.19 shows that there is an optimal feed tray location. Figure 6.21 shows the effect of feed tray locations on temperature and composition profiles. This optimum location is the top of the reactive section.

2013. 10. 11. · 4,844 posts. Posted 11 October - 12:46 AM. Hi, 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

As the feed stage is moved lower down the column, the top composition becomes less rich in the more volatile component while the bottoms contains more of the 

Answer (1 of 4): We know that we can find feed tray location by maccab and thiele method but this method is use only for binary component. But in actual there is a multicomponent distillation so we can’t use maccab and thiele method. So for the multicomponent distillation you have to

2016. 4. 11. · Optimum feed tray location is that where the operating cost of the column is minimum, and minimum operating cost means minimum condenser and re-boiler duty. From the graph we find out that for 1.25 Rmin the theoretical number of stages comes out to be 212 and feed tray location being 123rd tray for minimum operating cost. Table -4

2011. 6. 1. · Abstract. Selecting optimum feed location is critical to maximizing distillation column performance. An ideal feed location is feeding to a section of the distillation column where column internal

Answer: Hi No the feed isn’t always fed to the middle tray in a distillation column. Feed tray for a distillation column is optimised. For a given number of trays in a column with a given feed temperature, product specifications and operating pressure,
