Here is a listing of **sept**:

% sept: calculates the fractions to be used with frac
% function frac=sept(i1,x1in2,xs1,in)
% Argument Gives
% i1 index of compound that is known in the exit streams
% x1in2 mol or (mass) fraction of i1 in the second exit stream
% xs1 composition of the first exit stream, mol or (mass)
fractions
% in index of the inlet stream
% sept returns in frac, the fractions to be used in SEP
% For addtional help and picture, see PICSEPT
% Example: >> ti=sept(1,.1,[0.8333 0 0.1668],5);
% >> sep(ti,5,[4 3])
% OKB, TYLC
global ns
x1=xs1(i1);
n1=((x1in2*sum(ns(in,:)))-ns(in,i1))/(x1in2-x1);
frac=n1*(xs1./ns(in,:));
