✦ Synopsis

A method is proposed for achieving the optimum design, in the sense of minimum plates, for conventional and complex distillation columns for any set of specifications directly dependent on product purity which might be imposed by the designer, The method uses the calculational procedure of Thiele and Geddes, the 0-method of convergence, and sequential-search procedures. Illustrative examples chosen from a large number of design problems solved by this method are presented. most approximate methods ( 2 , 3, 4). For example, in the use of the proposed method in the design of conventional columns, two of the inputs consist of the ranges of the Vol. 11, No. 4

## Abstract Plots of water‐rate and packing‐shape correction factors for four commonly used sizes of Raschig rings to use with a modified Fanning equation are given. These are for fluid rates commonly associated with distillation, as distinct from absorption. Experimental evidence is given to show
