The detailed results of the simplified calculation are as follows.: MINIMUM REFLUX RATIO 1.07745 FEED CONDITION Q 1.00000 FENSKE MINIMUM TRAYS 16.76383 OPERATING REFLUX RATIO 1.20 * R-MINIMUM TOTAL FEED R/R-MIN M/M-MIN REFLUX DUTY, M * KCAL/HR TRAYS TRAY RATIO CONDENSER REBOILER ----- ---- ------- ------- ------ ---------- ---------- 42 14 1.100 2.476 1.185 -5.246E-01 5.560E-01 39 13 1.150 2.349 1.239 -5.375E-01 5.689E-01 38 13 1.200 2.246 1.293 -5.505E-01 5.819E-01 36 12 1.250 2.156 1.347 -5.634E-01 5.948E-01 35 12 1.300 2.076 1.401 -5.763E-01 6.077E-01 But I don’t know where this result comes from. Can anyone give me some advice? Thank you.~

I'm confused. I've already given it to you. The actual reflow ratio is 1.2 times the minimum reflow ratio. You know the minimum reflow ratio. Just multiply it and you'll be fine.
Just calculate an initial value first, and then optimize it according to your purpose.
With SHOTCUT, the reflux ratio can be found by giving the number of plates.
What the 2nd floor said is right, study hard.* English, haha
in original report: MINIMUM REFLUX RATIO 1.07745. That is, the minimum reflux ratio Rmin=1.07745, so the actual reflux ratio can be 1.2-1.8Rmin.
