Optimal feed locations and number of trays for distillation columns Optimization of Distillation Separations Using Feed Splitting by a 

Abstract: - Determination of tray location in multicomponent distillation is important for the designing simplification to determine optimum separation.

by using the optimum feed tray locations for each feed composi-tion can be quite significant [Luyben, 1975]. In this case, for ex-ample, the V/F ratio calculated by using the 32nd feed tray is 10% higher than that using the 24th feed tray for the feed composition of 0.4. As shown in the middle curves of Fig. 6, the optimum feed tray location of

Feed tray location Particularly when the number of trays is small, the location of the feed tray has a marked effect on the separation in the column. An estimate of the optimum location can be made with the Under-wood-Fenske equation (13.116), by applying it twice, between the overhead and the feed and between the feed and the bottoms.The ratio of the numbers of rectifying Nr
