Why does the result graph I made show that as the number of trays increases, the heat load at the bottom of the tower also increases?

As shown in the picture and description, I don't know where the problem lies. Can anyone help solve it?
Doesn’t it require an increase in energy to increase the number of plates to improve the separation accuracy? The separation accuracy of your separation tower with three plates and 30 plates is different? Isn’t it right to increase the energy?
One of the factors that has the greatest impact on hot and cold compliance is the reflow ratio. You can first look at the changes in the reflow ratio.
The separation accuracy has not changed. . . This figure is a figure obtained through sensitivity analysis. The effect of the number of trays and feed position on the heat load at the bottom of the tower was verified.
The tower is set to have no pressure difference, and the pressure of the entire tower is 250kpa.
The reflow ratio is set to a fixed value, so I don't know where the problem lies. Another related problem is that when the total number of plates is fixed and the impact of the feed position on the heat load at the bottom of the tower is separately considered, it is found that when the feed is the first plate, the heat load at the bottom of the tower is the lowest. . Are the causes of these two problems the same?
It is best to upload the file and take a look. Under normal circumstances, it should be the optimal feed plate with the smallest load (fixed tower top accuracy and flow rate), and the mixing effect at this time is the smallest.
See the attachment for the file. Take a look at the results in the sensitivity analysis
