5.8 Extraction of a solute with: phaseg

Here is a listing of phaseg:

  function er=phaseg(iw,ioil,isol,dis,in,out,x)
  % Phaseg: Calculates solute distribution in 2-phase separation using modules.
  % function er=phase(iw,foil,isol,dis,in,out,x)
  % Argument   Gives
  %   iw     index of the water in cnms.
  %   ioil   index of oil in cnms.
  %   isol   index of the solute in cnms.
  %   dis    distribution coefficient
  %   in     index of the inlet stream
  %   out    indices of the exit streams
  %    x     fraction of solute going into
  %          the top phase
  %  er returns the difference between dis and the
  %     ratio actually set for the solute in the exit streams.
  % For additional help and picture see PICPHASEG
  % See also PHASE, IPHASEG, IPHASEGIN
  % Example: >> ssec2([0.1 0.9],'phaseg(1,2,3,3.0,3,[4 5],x)');
  % revised help by TYLC
  global ns
  v([iw ioil isol])=[0 1 x];
  sep(v,in,out)
  temp=sum(ns(out,:)');
  xs=ns(out,isol)./temp';
  er=dis-xs(1)/xs(2);
