Notes:
A modification is presented of the Kb method described by Holland. This modified procedure exhibits substantially improved convergence characteristics when compared with the unmodified procedure or with the classical bubble point approach. Further, it provides by far the fastest algorithm known to the author. A second procedure for determining stage temperatures is also given. In this method, flow equations as well as equilibrium relations are satisfied by the temperature profile at each iteration. Next, an improved scheme for handling nonideal mixtures is given. Finally, it is shown that a positive solution to the convergence acceleration equations of Holland may not exist when this procedure is applied to a purity specification.
